Carlotta subscribes to the HotBurn music service. She can download no more than 11 song files per week. Carlotta has already downloaded 8 song files this week. Write, solve, and graph an inequality to show how many more songs Carlotta can download.
Answers
The number of songs that can be downloaded is no more than 3.
i.e
Number of songs ≤ 3
What is inequality?It is a statement of an ordered relationship
- greater than,
- greater than or equal to,
- less than,
- less than or equal to between two numbers or algebraic expressions.
We have,
The number of songs that can be downloaded per week = S
S = No more than 11 songs.
This can be written as:
S ≤ 11
The number of songs already downloaded = 8
The number of songs that can be downloaded per week is:
S ≤ 11 - 8
S ≤ 3
Thus,
The number of songs that can be downloaded is no more than 3.
i.e
Number of songs ≤ 3

Answer:
The right answer is C I took the assessment
The solution is:
x = (z - y)/(a - b), represents the formula that could be used to find x, from the expression ax - bx + y = z.
What is simplification?Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
here, we have,
given that,
the expression is:
ax - bx + y = z
now, we have to : Solve for x
Subtract y on both sides:
ax - bx = z - y
Factor GCF:
x(a - b) = z - y
Isolate x:
x = (z - y)/(a - b)
Hence, The solution is:
x = (z - y)/(a - b), represents the formula that could be used to find x, from the expression ax - bx + y = z.

Whats 95 closer to 64 or 125
Answers
95-64=31
so it would be 125
To find out if 95 is closer to 64 or 125, we compare the absolute differences. 95 is 31 units away from 64 and 30 units away from 125. Therefore, 95 is closer to 125.
To determine whether 95 is closer to 64 or 125, we need to calculate the absolute differences between 95 and each of the two numbers:
Difference between 95 and 64: |95 - 64| = 31Difference between 95 and 125: |125 - 95| = 30Since 30 is smaller than 31, 95 is closer to 125 by 1 unit.

A high school had 740 students at the start of the year, but then some students left the school. After that, the school had 726 students. If s = the number of students who left the school, which mathematical sentence expresses the information above? A. 740 - s = 726 B. s - 740 > 726 C. s - 740 = 726 D. 740 - s > 726
Answers
Answer:
A. 740 - s = 726
Step-by-step explanation:
The equation states: the original number of students, subtracting the number of students that left, represents the number of students now.
Correct option is (A) 740 - s = 726
Given that a high school had 740 students at the start of the year.
However some students left the school. After that, the school had 726 students.
Let 's' be the the number of students who left the school
Thus as 's' students left the school, there will be deduction of 's' students from the school
Now this deduction 's' would be from the 740 students which were present in the school and the resultant students after deduction is given to be '726'
Thus we can form the mathematical expression as follows,
[tex]740 - s = 726[/tex]
Thus '740 - s = 726' is the requires expression
A student wants to find the density of an egg as part of an experiment. If the weight of the egg is 57 g, and its volume is 48.25 mL, which measurement could be the most precise value of the density of the egg, in g/mL?
Answers
[tex]density=\frac{mass}{volume}[/tex]
We have a mass of 57g and a volume of 48.25mL, so then:
[tex]density=\frac{57g}{48.25mL}[/tex]
The most precise value of the density of the egg will be 1.18 g / mL.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Weight of the egg = 57 g
Volume = 48.25 mL
Now,
Since, Weight of the egg = 57 g
Volume = 48.25 mL
We know that;
⇒ Density = Mass / Volume
Substitute all the values, we get;
⇒ Density = 57 g / 48.25 mL
= 1.18 g / mL
Thus, The density of the egg = 1.18 g/mL

To solve for a variable, you have to isolate the variable that you want to solve. In this case, we want to solve for "x," so we must isolate "x."
So, subtract 1/5y from both sides.
3x = -1/5y + 7
Then, divide both sides by 3.
3x ÷ 3 = (-1/5y + 7) ÷ 3
Simplify.
x = -1/15y + 7/3

For your summer babysitting jobs you have 10 weeks to work before your family vacation and before you return to school in the fall. You are planning on earning and saving at least $1500 for your future car. Mrs. Harris is paying you $8.00 an hour to babysit during the day and Mrs. Sanchez is paying you $6.00 per hour to babysit her child in the evening.
• Let x = the number of hours you babysit for Mrs. Harris
• Let y = the number of hours you babysit for Mrs. Sanchez
1. Write an inequality describing the number of hours you want to work each week to reach your summer goal of at least $1500. Remember you have 10 weeks to work. How much do you want to average per week?
Answers
The inequality that represents the given situation is (8x + 4y [tex]\geq[/tex] 1500) and this can be determined by using the given data.
Given :
You have 10 weeks to work before your family vacation and before you return to school in the fall. For your future car you are planning on earning and saving at least $1500.$8 per hour is paid by Mrs. Harris.$6 per hour is paid by Mrs. Sanchez.The following steps can be used in order to determine the inequality that describes the number of hours you want to work each week to reach your summer goal of at least $1500:
Step 1 - Let the number of hours you babysit for Mrs. Harris be 'x' and the number of hours you babysit for Mrs. Sanchez be 'y'.
Step 2 - So, the inequality that represents the given situation is given below:
8x + 4y [tex]\geq[/tex] 1500
Now, the average per week can be determined by dividing 1500 by 10. So, you have to make $150 per week.

The length of a rectangle is five times its width. The perimeter of the rectangle is at most 96 cm. Which inequality models the relationship between the width and the perimeter of the rectangle?
2w+2⋅(5w)>96
2w+2⋅(5w)<96
2w+2⋅(5w)≤96
2w+2⋅(5w)≥96
Answers
Let
L--------> the length of the rectangle
W-------> the width of the rectangle
we know that
the perimeter of the rectangle is equal to
[tex]P=2L+2W[/tex]
[tex]P\leq 96\ cm[/tex]
so
[tex](2L+2W)\leq 96[/tex] ---------> equation [tex]1[/tex]
[tex]L=5W[/tex] ---------> equation [tex]2[/tex]
Substitute equation [tex]2[/tex] in equation [tex]1[/tex]
[tex]2*(5W)+2W\leq 96[/tex]
therefore
the answer is the option
2w+2⋅(5w)≤96
Answer:

Answers
Answer: [tex]59.8^{\circ} F[/tex]
Step-by-step explanation:
Given : Joaquin recorded a temperature of 62°F this morning for science class.
The temperature increased [tex]6\dfrac{1}{2}^{\circ}F[/tex] in the afternoon before decreasing 8.7°F in the evening.
We can write [tex]6\dfrac{1}{2}[/tex] as [tex]6+\dfrac{1}{2}=6+0.5=6.5[/tex] .
Now According to the question , the temperature at evening will be :-
[tex]62^{\circ}F+6\dfrac{1}{2}^{\circ}F-8.7^{\circ}F\\\\=62^{\circ}F+6.5^{\circ}F-8.7^{\circ}F\\\\=(62+6.5-8.7)^{\circ}\ F=59.8^{\circ}\ F[/tex]
Hence, the evening temperature was [tex]59.8^{\circ} F[/tex] .
