What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Cost of the computer = $356.75
The value of the computer decreases by 11(3/4) every year.
= 11(3/4)
= 47/4
= $11.75
After three years.
The change in the value of the computer.
= 3 x $11.75
= $35.25
The expected value of the computer after 3 years.
= $356.75 - $35.25
= $321.5
Thus,
The expected value of the computer after 3 years is $321.5

Painting:
Lisa is painting a fence that is 26 feet long and 7 feet tall. A gallon of paint will cover 350 square feet. Write and solve a proportion to determine how many gallons of paint Lisa will need
(Also can you explain how you solved it? Just in case I've been doing all the other ones wrong)
Answer:
Step-by-step explanation:
First we need to find the area of the fence, since paint covers square feet and squared units refers to area. The area of the fence is 26 x 7, which is 182 sq ft. If one gallon of paint will cover 350 sq ft, your proportion will look like this, with gallons of paint on top and square feet on the bottom. 1/350 = x/182 Cross multiply to get 350x = 182 and x = .52, just a bit over a half of a gallon of paint.
Anthony wants to limit the class sizes to 24 students per class. If there are 192 students in each grade, what is the minimum number of classes per grade?

Answer:
(x, y) = (no solutions, 0)
Step-by-step explanation:
2x - 4y = -10
2x + y = 10
(2x - 4y) - (2x + y) = -10 + 10
-3y = 0
y = 0
x has no solutions.

Question 10 (2 points)
An economist creates a scatter plot comparing years of experience to yearly salary (in dollars) at a particular company. The trend line through the data can be described by the equation y = 9,000x + 25,000.
What is the slope and what does it mean?
Question 10 options:
9,000; For their every year of experience an employee has, their salary goes up by this amount.
25,000; For their every year of experience an employee has, their salary goes up by this amount.
25,000; Regardless of how much experience an employee has, this is the minimum amount the employee will earn at this company.
9,000; Regardless of how much experience an employee has, this is the minimum amount the employee will earn at this company.
Answer:
Question 6: The slope is 5/3 because the y-intercpet is your rise and it rose up 5 units and x-intercept is your run so it shifted 3 units to the right which means the whole thing is also positive.
Question 9: $135
Question 10: Its either the first or last option
Step-by-step explanation:
Answer:
The answer for question 6 would be 5/3
and for question 9 the answer would be 135
and I believe question 10 is 9,000; For their every year of experience an employee has, their salary goes up by this amount.
Step-by-step explanation:
Slope (also can be called rate of change) is solved by change in the y variable/change in the x variable or also known as rise/run

Answer:
[tex] \underline{ \underline{ \boxed{ \text{Subtract \: 2 \: from \: both \: sides}}}}[/tex]
Step-by-step explanation:
Since we want constants only on the right hand side , we have to remove 2 which is on the left hand side. The opposite of +2 is -2 and whatever we do to one side , we must do to the other side. So, The first step that would be used to solve the equation should be Subtract 2 from both sides.

What is the value of the expression shown below?
10 + (2 x 3) to the power of 2 ÷ 4 × 1/2 to the power of 3
11 and 1/8
25 and 1/6
69
82
Answer:
11 and 1/8
Step-by-step explanation:
We can do this in the format of PEMDAS
Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction
10 + (2 × 3[tex])^{2}[/tex] ÷ 4 × [tex]\frac{1}{2} ^{3}[/tex]
Let's do the parenthesis first
10 + [tex]6^{2}[/tex] ÷ 4 × [tex]\frac{1}{2} ^{3}[/tex]
Now we can do the fraction with the exponent second
10 + [tex]6^{2}[/tex] ÷ 4 × [tex]\frac{1}{8}[/tex]
Now we can do the other exponent
10 + 36 ÷ 4 × [tex]\frac{1}{8}[/tex]
Now we can divide the 36 and 4
10 + 9 × [tex]\frac{1}{8}[/tex]
Now we can multiply the 9 and [tex]\frac{1}{8}[/tex]
10 + [tex]\frac{9}{8}[/tex]
And we can convert the improper fraction to a mixed number
10 + 1 1/8
And now we can add them up, the 2 whole numbers and the fraction stays the same
11 1/8

Oscar has a $2,500 balance on his credit card that accumulates 14.5% interest compounded annually. Which of the following could be used to find the balance on the card after 5 years?
A. A = 2500(1 + 0.145)5
A. , A... equals... 2,500... 1 plus 0 point 1 4 5 to the 5th power,
B. A = 2500 × 0.145 × 5
B. , , A.... equals... 2,500 times 0 point 1 4 5 times 5, ,
C. A = 2500(1 + 0.05)14.5
C. , , A... equals... 2,500.... 1 plus 0 point 0 5 to the 14 point 5 power, ,
D. A = 0.145(1 + 2500)5
Answer:
a
Step-by-step explanation:
2500 x 1 = 2500
2500 x .145 = 362.5
2500 + 362.5 = 2,862.5
2,862.5 x 5 = 14,312.5

The equation |x| = 100 has two solutions. x = -100 and x = 100 Write two solutions for each variable in the equations
a = 7 a = __________ and a = __________
p = 41 p = __________ and p = __________
y = 256 y = __________ and y = __________
I think you meant |a|=7, |p|=41, and |y|=256. In that case, a=7 or -7, p= 41 or -41, and y=256 or -256.
