A. 5y = x
b. 5(6.5) = $32.50
c. 47.50/5 = 9 hours and 30 minutes
d. 9y = x
e. 9(8.5) = $76.50
f. 49.50/9 = 5 hours and 30 minutes
Answer: y= 8x + 7
y-7 = 8 ( x)
y-7= 8x

Answer:
BC = 28
Step-by-step explanation:
Since the triangle is equilateral then all 3 sides are congruent.
Equate AB and AC and solve for x, that is
12x + 4 = 8x + 12 ( subtract 8x from both sides )
4x + 4 = 12 ( subtract 4 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2, thus
AC = 8x + 12 = (8 × 2) + 12 = 16 + 12 = 28
Since the 3 sides are congruent then BC = 28
Answer:
<u>The taxi ride was for 23 miles.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Function of total cost (C)ₙ = 10 + 1.50n
n = Miles of the taxi ride
C = Cost in dollars of the taxi ride
Total cost = $ 44.50
2. For how many miles was the taxi ride?
Let's replace the cost of the taxi ride in the function given for solving for n, this way:
10 + 1.50n = 44.50
1.50n = 44.50 -10
1.50n = 34.50
n = 34.50/1.50
n = 23
<u>The taxi ride was for 23 miles.</u>
Answer:
x= -7
Step-by-step explanation:
2x+16+7=x+16
2x+23=x+16
x= -7
