Step-by-step explanation:
step 1. 4x + 27 + 3x = 90 (definition of a rectangle)
step 2. 7x = 63 (collect like terms. subtract 27 from both sides)
step 3. x = 9 (divide both sides by 7)

Answer:
FV= $34,222.33
Step-by-step explanation:
<u>First, we need to calculate the weekly interest rate:</u>
Weekly interest rate= 0.0289/52= 0.00056
<u>To calculate the future value (FV), we need to use the following formula:</u>
FV= {A*[(1+i)^n-1]}/i
A= weekly deposit
n= 15*52= 780
A= $35
FV= {35*[(1.00056^780) - 1]} / 0.00056
FV= $34,222.33
Answer:
y= 250 - 2x
Step-by-step explanation:
She spends $2 per bottle, which is my it's 2x.
She has a total of 250, and she spends $2 per bottle, so you subtract 2x from 250, which leaves the equation at y = 250 - 2x
