Answer:
The value of the expression is [tex]-17x[/tex].
Step-by-step explanation:
Consider the provided expression.
[tex]4x - 2x -20x + x[/tex]
To solve the above expression we need to add the like terms as shown.
[tex]4x+x - 2x -20x[/tex]
[tex]5x - 22x[/tex]
[tex]-17x[/tex]
Hence, the value of the expression is [tex]-17x[/tex].

What is the perimeter of triangle PQR? Show your work.
Answers
According to CPCTC, corresponding parts of congruent triangles are congruent, which means that PR and SU are equal.
3y-2=y+4
3y=y+6
2y=6
y=3
3(3)-2=9-2=7
7+4+6=17
The perimeter is 17 feet.
Hope this helps!
Answer:
PQR= 17 ft
Step-by-step explanation:
1. PQ ≅ ST = 4 ft (Given)
2. ∠PQR ≅ ∠STU (Given)
3. QR ≅ TU = 6 ft (Given)
Which makes the two triangles congruent by SAS postulate.
Now, from CPCTE, PR = SU
3y-2=y+4
Solve for y and simplify
Subtract Y from both sides.
Add 2 to both sides
3y-y=4+2
Add
2y=6
Divide both sides by 2
Y=3
Now, side PR is given by plugging in 3 for Y. PR = 3(3) - 2 = 9 - 2 = 7 ft. The perimeter of a triangle PQR is the sum of all of its sides. Perimeter = PQ + QR + PR = (4 + 6 + 7) ft = 17 ft. The perimeter of triangle PQR is 17 ft.

You miss 3 out of 10 questions on a science quiz and 4 out of 15 questions on a math quiz. Which quiz has a higher percent of correct anwsers?
Answers
The quiz with a miss of 3 questions out of 15 has the higher percentage.
As mentioned in the question,
You miss 3 out of 10 questions on a science quiz and 4 out of 15 questions on a math quiz.
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
here,
Percentage of correct answer in 1st quiz = 100% - 3/10 × 100% = 70%
Percentage of correct answer in 2nd quiz = 100% - 4/15 × 100% = 77%
The percentage of 2nd quiz is greater than 1st quiz.
Thus, the quiz with a miss of 3 questions out of 15 has the higher percentage.

How to solve a system of equations using elimination
Answers
To solve a system of equations by addition, also called elimination, the goal is to cancel out one of the variables by adding the equations together. However, in some cases, you will need to multiply one or both of the equations by a number in order to create a scenario where one of the variables will cancel out when the equations are added together. As long as you cancel a variable out, you will be able to add the equations together and solve for the variable. If you find one variable, you can find the other one easily.

Answers
5x7= 35sqft
20x28= 560sqft
If 1 bag makes 35sqft, 560sqft is how many bags;
This is how I write the equation;
1x bag 35sqft
X 560sqft
Solution: (560x1) : 35 = 16bags
I solved this based on my way of logic. I'd appreciate if you let me know if the answer is correct.
area of 5 x 7 porch = 5*7 = 35 sq. ft.
area of 20 x 28 porch = 20 *28 = 560 sq. ft.
560 / 35 = 16
so 16 bags are needed
I need help with number 24. It says is it possible that Lauren answered more questions correctly on the second math test than Antoine did? Explain.
Answers
Calculating the probability of getting more than 75% of answers right with random guessing is unlikely to yield a count higher than 24 correct answers. Therefore it is improbable for Lauren to have answered more questions correctly than Antoine. However, without specific data on Lauren's and Antoine's test results, we cannot say with absolute certainty.
Explanation:To ascertain if Lauren could have answered more questions correctly on her second math test than Antoine, we need to understand the concept of probability. In this case, we want to find P(x > 24) which means we want to find out if getting more than 75 percent (or more than 24 correct answers) out of 32 questions is possible. That is, did Lauren score more than 24? However, the probability of getting more than 75 percent of the 32 questions correct when randomly guessing is practically zero. Mathematically, we express this as P(x > 24) = 0.
This suggests obtaining a score higher than 24 is very difficult, and therefore it's unlikely that Lauren answered more questions correctly than Antoine, especially if answering was based on random guessing. However, without specifics about Lauren's or Antoine's performance, we can't say definitively.

Suppose point J has coordinate of -2 and JK=4. Then what is the possible coordinate(s) for K? 4 2 or -4 -4 2 or -6
Answers
Given that point J is at -2 and the distance between J and K is 4, the possible coordinates for K are -6 (if you count 4 steps to the left) or 2 (if counted to the right on the number line).
Explanation:The given information tells us that point J has a coordinate of -2 and the distance JK equals 4. In a number line, distances can be counted to the left (negative direction) or to the right (positive direction). Therefore, point J will be 4 points to the left or right of, which means the coordinates for K could be -2-4 = -6 or -2+4 = 2.

At Algorithms Pizza they have the exponential pizza, which is a 24-inch cheese pizza that costs $17.50. Each topping for the pizza costs $2.35. If Connor ordered the exponential pizza and was charged $29.25, how many toppings were on his pizza? Justify your answer by using an algebraic equation to solve this problem step by step
Answers
Answer:
5 toppings.
Step-by-step explanation:
Let there were x toppings on the exponential pizza ordered by Connor.
Then charges for toppings = $2.35x
If the cheese pizza costs = $17.50
Total charges for the pizza = (17.5 + 2.35x)
Total cost of the cheese pizza with toppings = $29.25
Equation to find the number of toppings will be
29.25 = 17.5 + 2.35x
2.35x = 29.25 - 17.5
2.35x = 11.75
x = [tex]\frac{11.75}{2.35}[/tex]
x = 5
Therefore, number of toppings on the pizza will be 5.
Which situation is represented by the inequality? 3x + 5 > 2x + 15
Answers
Final answer:
The inequality 3x + 5 > 2x + 15 represents a situation in which x is greater than 10.
Explanation:
The inequality 3x + 5 > 2x + 15 represents a situation in which one side of the equation is greater than the other. To solve this inequality, we need to isolate x on one side of the equation. Here are the steps:
Subtract 2x from both sides of the equation: 3x + 5 - 2x > 2x + 15 - 2xSimplify both sides of the equation: x + 5 > 15Subtract 5 from both sides of the equation: x + 5 - 5 > 15 - 5Simplify both sides of the equation: x > 10So, the inequality 3x + 5 > 2x + 15 represents a situation in which x is greater than 10.
