Step-by-step explanation:
Answer:
x =5
Step-by-step explanation:
We can use proportions to solve this problem. Put the side of one triangle over the same side of the other triangle.
x 4
------ = ----------
40 32
Using cross products
32x = 4*40
32x = 160
Divide each side by 32
32x/32 =160/32
x =5
Answer:
x = -16
Step-by-step explanation:
2/3 x + 1 = 1/6 x -7
Multiply both sides of the equation by 6 to eliminate the fraction
6*(2/3 x + 1) =6( 1/6 x -7)
4x +6 = x -42
Subtract x from each side
4x-x +6 = -42
3x +6= - 42
Subtract 6 from each side
3x+6-6 = -42-6
3x = -48
3x/3 = -48/3
x = -16
