Answer:
x = 9 1/3
Step-by-step explanation:
We can use the ratios of similar triangles to solve
x 7
----------- = ------------
x+8 13
Using cross products
13x = 7(x+8)
Distribute
13x = 7x+56
Subtract 7x from each side
13x-7x = 7x+56-7x
6x = 56
Divide each side by 6
6x/6 = 56/6
x= 28/3
x = 9 1/3
Answer:
w=15
Step-by-step explanation:
The way I found the answer is dividing 120 by 8 which equaled 15 and I made sure it was correct as I multiplied 8 by 15 and the answer was 120.
Step-by-step explanation:
50-50+15d =125-50
15d = 75
15d/15=75/15
d=5
M + R + G = 119
G = 3M
M = R + 6 —> R = M - 6
1st equation: M + (M-6) + (3M) = 119
5M -6 = 119
5M = 125
M = 25
G = 3(25) = 75
R = (25) -6 = 19
