- 8/9x - 4/45x + 1/5x = - 70

lara31 [8.8K]

Answer:

x = 90

Step-by-step explanation:

- $\frac{8}{9}$ x - $\frac{4}{45}$ x + $\frac{1}{5}$ x = - 70

Multiply through by 45 ( the LCM of 9, 45, 5 ) to clear the fractions

- 40x - 4x + 9x = - 3150 , that is

- 35x = - 3150 ( divide both sides by - 35 )

x = 90

One side of a triangle is twice as long as a second side. The third

natta225 [31]

Answer:

The longest possible values of the other two sides are 7 ft and 14 ft

Step-by-step explanation:

Let one side of the triangle be x and the other, 2x

Perimeter of a triangle = sum of all sides; i.e x+2x+33

Therefore, x+2x+12=33

Solve for x;

3x=33-12

3x=21

Divide both sides by 3; x=21/3

therefore, x=7 and

2x= (2*7) = 14

The longest possible values of the other two sides are 7 ft and 14 ft
