We have a sentence - "10 more than P is -3".
We have to determine the expression that represents the sentence.
Express the statement - "The difference of x and y is equal to n" in the form of expression.The expression representing the above statement is -
n = x - y
According to the question, we have -
10 more than P is -3
We can write it as a expression -
P + 10 = -3

To start the school year, a teacher spends $54.35 in school supplies for her classroom. During the course of the year, she will restock her supplies and will spend $22 each time she restocks the supplies. The expression below describes this situation.
22x+54.35
In this expression, what does the term 22x describe?
A. the amount she spends restocking her supplies
B. the total amount she spends money on restocking her supplies
C. the number of times she restocks her supplies
D. the amount she originally spends on supplies
Answer: B. the total amount she spends money on restocking her supplies
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
During the course of the year, she will restock her supplies and will spend $22 each time she restocks the supplies
22x+54.35
SO, the term 22x equals to $22 multiplied by the times she restocks the supplies. For example: if she restocks the supplies 5 times, the total amount will be:
22 (5)+ 54.35
So, the term 22x describes the total amount she spends money on restocking her supplies. option B
For what values of b does the value of the fraction 5−2b /4 belong to the interval [−2; 1]?
Answer: The required value of b lies in the interval [0.5, 6.5].
Step-by-step explanation: We are given to find the value of b so that the following fraction belong to the interval [−2, 1] :
[tex]f=\dfrac{5-2b}{4}.[/tex]
According to the given information, we can write
[tex]-2\leq f\leq 1\\\\\Rightarrow -2\leq \dfrac{5-2b}{4}\leq1\\\\\Rightarrow -8\leq 5-2b\leq 4\\\\\Rightarrow -8-5\leq-2b\leq 4-5\\\\\Rightarrow -13\leq -2b\leq -1\\\\\Rightarrow 13\geq 2b\geq 1\\\\\Rightarrow \dfrac{13}{2}\geq b\geq \dfrac{1}{2}\\\\\Rightarrow 6.5\geq b\geq 0.50[/tex]
Thus, the required value of b lies in the interval [0.5, 6.5].

Mia hiked along a 2,250-foot mountain trail. She stopped 4 times along the way to rest and then a fifth time at the end of the trail, and she walked the same distance between each stop,How far did Mia hike before the first stop?
Answer:
Mia hiked 450 ft before the first stop.
Step-by-step explanation:
Mia hiked along a 2250 foot mountain trail.
She stopped 4 times, she rested and after that stopped 5 times.
She walked the same distance between each stop.
It means 5 stops and the same distance with each time.
We need to calculate the distance between each stop. Total distance T = 2250 ft, and stops S = 5.
We can isolate the distance of each Stop E from:
T = S*E
E = T/S = (2250 ft)/(5)
E = 450 ft.
Finally, She hiked 450 ft before the first stop.
Mia hiked 450 feet before the first stop.
What is the distance?Distance is defined as the product of speed and time.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operations is called the arithmetic operator.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
Given that Mia hiked along a 2250-foot mountain trail.
She stopped 4 times along the way to rest and then a fifth time at the end of the trail,
And she walked the same distance between each stop.
It indicates 5 stops with a constant distance between them.
To determine the distance between each stop.
Total distance D = 2250 ft, and stops X = 5.
Each Stop Y's separation from the other can be determined.:
⇒ D = X×Y
⇒ Y = D/X
Substitute the value of D and X in the above equation,
⇒ Y = (2250 feet)/5
Divided by 5
⇒ Y = 450 feet.
Hence, Mia hiked 450 feet before the first stop.

An architectural drawing of a building shows the elevation of the basement floor to be –12 feet. The elevation of the roof is 32 feet. What is the total distance from the roof to the basement floor?
The total distance from the roof to the basement floor in the architectural drawing is 44 feet, found by adding the basement's distance from ground level (12 feet) to the roof's elevation (32 feet).
Explanation:In the given scenario, we need to find the total distance from the basement to the roof. Given the elevation of the basement is -12 feet and the elevation of the roof is 32 feet, we simply need to add these two distances together. Since the basement is below ground level, its elevation is negative. Therefore, its distance from the ground level is 12 feet, not negative 12. We can treat this as an absolute value.
To calculate the total distance, we add the absolute value of -12 (which is 12) to 32, which gives us 44 feet. Thus, the total distance from the roof to the basement floor is 44 feet.

In if 5/7 of students are wearing jeans today and there are about 27 students in the class how many students are wearing the jeans today
Final answer:
By calculating 5/7 of 27, we find that approximately 19 students are wearing jeans today after rounding down to the nearest whole number.
Explanation:
To find out how many students are wearing jeans, we need to calculate 5/7 of the 27 students in the class.
First, we determine the value of one seventh of the class by dividing the total number of students by 7:
27 ÷ 7 = 3.8571 (we can round this to 3.86 for simplicity)
Next, we multiply this result by 5 to find five sevenths:
3.86 × 5 = 19.3
Since we cannot have a fraction of a student, we round down to the nearest whole number. Therefore, approximately 19 students are wearing jeans today.
It's important to understand and apply fractions and division to solve such mathematical problems. This example showcases the practical application of these concepts.

Abebe is saving money from work and his Mom will give him an extra
1919
of whatever he saves. If Alejandro saves $23, how much will his mom give him?
$5.26
$2.56
$5.11
$6.52
Abebe's mom will give him ¼ of whatever he saves. If Abebe saves $23, his mom will give him 0.25 times $23, which is $5.75.
Explanation:The question asks how much money Abebe's mom will give him if she gives ¼ of whatever he saves, and he saves $23. To find out how much his mom will give him, we must calculate ¼ of $23.
If Abebe saves $23, and his Mom will give him an extra $19.19 of whatever he saves, you can calculate the total amount he will have as follows:
Total amount = Savings + Mom's extra contribution
= $23 + $19.19
= $42.19
Therefore, Abebe will have a total of $42.19. None of the provided options ($5.26, $2.56, $5.11, $6.52) match this amount. It seems there might be an error in the answer choices or the problem statement. Please double-check the values or context provided.
Step 1: Convert the fraction ¼ to a decimal by dividing the numerator (1) by the denominator (4), which is 0.25.
Step 2: Multiply the decimal equivalent of ¼ (0.25) by the amount saved by Abebe ($23).
Step 3: Perform the calculation: 0.25 × $23 = $5.75.
Therefore, Abebe's mom will give him $5.75.
Final answer:
Abebe's mom will give him 19% of $23, which is calculated by multiplying 0.19 by $23, resulting in $4.37.
Explanation:
The subject of the question is Mathematics, specifically it deals with a percentage problem that involves finding what fraction of an amount will be added to it. To find out how much money Abebe's mom will give him based on the extra 19% of whatever he saves, we simply need to calculate 19% of $23. The calculation is as follows:
Convert the percentage to a decimal: 19% = 0.19.
Multiply this decimal by the amount saved: 0.19 × $23 = $4.37.
Therefore, Abebe's mom will give him an additional $4.37.

In triangle QRS, QR = 2x + 5, RS = 3x - 1, and SQ = 5x. Solve for x.
To solve for x in triangle QRS, set up an equation using the given information. However, there is no unique solution for x.
Explanation:To solve for x in triangle QRS, we need to set up an equation using the given information. Firstly, observe that the sum of the lengths of the three sides of a triangle is equal to the perimeter of the triangle. So, we have (2x + 5) + (3x - 1) + (5x) = perimeter of QRS. Simplifying this, we get 10x + 4 = perimeter of QRS. Next, we need to consider the fact that the perimeter of a triangle is equal to the sum of the lengths of its sides. So, we can set up the equation 10x + 4 = QR + RS + SQ. Substituting the given lengths, we have 10x + 4 = (2x + 5) + (3x - 1) + (5x). Solving this equation will give us the value of x.
10x + 4 = 2x + 5 + 3x - 1 + 5x
10x + 4 = 10x + 4
When we simplify this, we see that both sides of the equation are equal. Therefore, x can take on any value and there is no unique solution for x in this case.
