Answer:
0.87 which is 13/15
Step-by-step explanation:
6/5 becomes 18/15
3/3 becomes 15/15
18/15-15/15 is 13/15
13 divided by 15 is about 0.87
She used the area of a square formula instead of area of a rectangle. she should have done A =(1/2)(19)(18) and gotten 171 in^2

Answer:
see explanation
Step-by-step explanation:
Part 1
Obtain the equation in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (1, 80) and (x₂, y₂ ) = (2, 110) ← 2 points from the table
m =
= 30
Given the point (0, 50 ) ⇒ c = 50
D(g) = 30g + 50 ← linear equation
A
D(6.5) = (30 × 6.5) + 50 = 195 + 50 = 245
B
D(4.25) = (30 × 4.25) + 50 = 127.5 + 50 = 177.5
C
D(50) = (30 × 50) + 50 = 1500 + 50 = 1550
