Giselle pays $210 in advance on her account at the athletic club. Each time she uses the club, $15 is deducted from the account. Model the situation with a linear function.
b = 195 – 15x
b = 210 + 15x
b = 195 + 15x
b = 210 – 15x
Solve the linear equation 2(3x + 2) = 2x – 1 + x. State the property that justifies your first step and why you
chose it.
Answer:
x = -5/3
Step-by-step explanation:
2(3x + 2) = 2x - 1 + x
2 × 3x + 2 × 2 = 2x + x - 1
6x + 4 = 3x - 1
3x = -5
x = -5/3
Hayley loves to shop for make up. She went to her favorite store and bought eye shadow for $5.99, 2 bottles of nailpolish for $7.50 each and a tube of mascara for $8.50.

Vedant runs around a square park of side 42m, three times. Rehan runs around a rectangular park of length 40m and breadth 18m, five times. Who covers more distance? By how much?
Answer:
Rehan;
76m
Step-by-step explanation:
Distance covered by running around square park :
Perimeter of square = 4s ; s = side length of square
Perimeter = 4 * 42m = 168 m
Total distance covered = 168m * 3 = 504m
Distance covered by running around rectangular park :
Perimeter of rectangle = 2(l + w) ;
Perimeter = 2(40 + 18) = 2(58) = 116 m
Total distance covered = 116m * 5= 580m
580m - 504m = 76m
Rehan covered more distance

Step-by-step explanation:
The value of W is inversely proportional to m. If w=8 then m=25, What is m when W is 20?Show me all the steps please?
Answer:
m = 10
Step-by-step explanation:
The values of w is inversely proportional to m
Mathematically the above statement is expressed as:
w ∝ 1/m
w = k × 1/m
w = k/m
Where k is the Proportionality Constant
First step
Solve for k
If w=8 then m=25
w = k/m
8 = k/25
Cross Multiply
k = 25 × 8
k = 200
Second step
what is m when w=20? Show me the steps please
We solve for m
w = k/m
k = 200
20 = 200/m
Cross Multiply
20m = 200
m = 200/20
m = 10

Savannah has $92,637 in a savings account that earns 9% annually. The interest is not compounded. How much interest will she earn in 5 years
Answer:
$41686.65
Step-by-step explanation:
Given data
Principal = $92,637
Rate= 9%
Time= 5 years
The simple interest expression is given as
SI= PRT/100
Substitute
SI= 92637*9*5/100
SI= 4168665/100
SI=$41686.65
Hence the interest is $41686.65

What are Linear Equations?An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution
On a graph, a linear equation forms a straight line. On a graph, a nonlinear equation produces an S-curve, a bell curve, or another nonlinear shape.
Given data ,
Let the linear function be represented as A
Now , the value of A is
The total cost for the SUV is given by
y₁ = 2,840x + 17,980
And , the total cost for the car is
y₂ = 3,210x + 17,980
when x = 2 years
y₁ = $ 23,660
y₂ = $ 24,400
The cost of the car is greater than cost of the SUV
Hence , the linear equations are solved

If you are being paid $55 for a days work which is an 8 hour shift how much would you get paid if you only worked 6 hours?
Answer:
You would get paid $41.25 if you only worked 6 hours.
Step-by-step explanation:
In order to find the answer, first you have to find the amount you are paid per hour by dividing the amount paid per day by 8 hours:
$55/8=$6.875
Then, you have to multiply the amount per hour for 6 to determine the amount you would get paid if you only worked 6 hours:
$6.875*6=$41.25
According to this, the answer is that you would get paid $41.25 if you only worked 6 hours.
