Answer:
GH = 15
Step-by-step explanation:
14. BC = 19
GH = 9x - 3
FE = 5x + 1
Given that GH is the midsegment of the trapezoid, therefore:
GH = (BC + FE)/2
Plug in the values
9x - 3 = (19 + 5x + 1)/2
9x - 3 = (20 + 5x)/2
Multiply both sides by 2
2(9x - 3) = 20 + 5x
18x - 6 = 20 + 5x
18x - 5x = 20 + 6
13x = 26
Divide both sides by 13
x = 2
✔️GH = 9x - 3
Plug in the value of x
GH = 9(2) - 3 = 18 - 3
GH = 15
Answer:
Length = 22cm
Step-by-step explanation:
Perimeter of a rectangle, P = 2(L + W)
Also, from the question, P = 80 cm
Therefore, P = 2(L +W) = 80
The length is 4 cm longer than the width
then, length, L = 4 + W
Slot in the value of L
2 {(4+W) + W} = 80
2(4 + 2W) = 80
8 + 4W = 80
Subtract 8 from both sides
8 - 8 +4W = 80 -8
4W = 72
Divide both sides by the coefficient of W which is 4
W = 18 cm
Recall,
L = 4 + W
L = 4 + 18
L = 22cm
Start with 21 cups , substract 5.5 (5 and one half) , 2.25( 2 and one fourth), and then divide by two (divided into 2 equal portions) and the result is 6.625 and if you divide the options as an improper fraction, you'll get 6 and five eights... so your answer is D.
Slope: constant rate of change
Since one time = 7, it would stay 7
As it’s $4 per game, the slope is the rate of change. “Per game”
Solution: 4
