C+a+b=p
move a to the other side
sign changes from +a to -a
C+a-a+b=p-a
C+b= p-a
move +b to the other side
C+b-b= p-a-b
Answer:
C= p-a-b
Answer:
a. <u>y = $3 + $2.50x,</u>
b. <u>$23</u>
Step-by-step explanation:
y is the total cost of x gallons of gasoline at $2.50/gallon.
a. The total cost of one car wash ($23 each) plus x gallons of gas is:
<u>a. y = $3 + $2.50x</u>
<u></u>
b. The cost of a car wash and 8 gallons (x=8) is:
b. y = $3 + $2.50*(8)
y = $3 + $20
<u>y = $23</u>
Answer:
A D E
Step-by-step explanation:
the figure shows that ABC is 90 degrees. So the two smaller angles add to 90 making A correct. (B isn't for obvious reasons - 180 is not 90.)
x + 4x - 85 = 90 Solve this to find the other 2 correct statements
5x - 85 = 90 Add 85 to both sides.
5x = 90 + 85 Combine
5x = 175 Divide by 5
5x/5 = 175/5
x = 35
Since ABD is a single x, that statement (D) is true.
4x - 85 = 4*35 - 85 = 140 - 85 = 55 which makes E true as well
Answer:
x = -2
