<span>d=420-65t. Geometric figure: Straight Line. Slope = -0.031/2.000 = -0.015; d-intercept = 420/1 = 420.00000; t-intercept = 420/65 = 84/13 = 6.46154. Rearrange: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : d-(420-65*t)=0.</span>
Answer:
7.5$
Step-by-step explanation:
This is because 11.25*3 = 33.75
and 8.25*5 = 41.25
41.25-33.75=7.5
9(n+3)=7n-3
1) distribute 9 into (n+3)
9n+27=7n-3
2) subtract 7n on both sides
2n+27=-3
3) subtract 27 on both sides
2n=-30
4) divide by 2
n=-15
Answer:
A= 24 m
Step-by-step explanation:
The formula for the area of a trapezoid is A= 
x h.
Using the formula you plug in the values:
A= 
x 3
2. Now you simplify the equation and solve
A = 
x 3
A = 8 x 3
A = 24
