Answer:

The answer is 25.

Step-by-step explanation:

A way to solve this problem is to set up a proportion: 64/100 x 16/x.

Cross multiply 64 with x to get 64x. Cross multiply 16 with 100 to get 1600.

Divide 1600 by 64 to get 25.

I hope this was clear! :)

The answer to the problem i asked

guapka [62]

8(4x+5)=136
Multiply the number outside of the parenthesis(8) with the numbers inside the parenthesis(4x and 5).
32x+40=136
Subtract 40 from both sides
32x=96
Divide both sides by 32 so the only thing remaining on the side of the variable is only the variable itself.
Final Answer: x= 3

Triangle ABC, with vertices A(5,2), B(7,6), and C(2,5), is drawn inside a rectangle, as shown below.

natka813 [3]

Answer:

9 units²

Step-by-step explanation:

calculate the area of Δ ABC as

area of rectangle - area of 3 outer right triangles

area of rectangle = 5 × 4 = 20 units²

area of left Δ = $\frac{1}{2}$ × 3 × 3 = 4 $\frac{1}{2}$ units²

area of Δ on right = $\frac{1}{2}$ × 2 × 4 = 4 units²

area of top Δ = $\frac{1}{2}$ × 5 × 1 = 2 $\frac{1}{2}$ units²

Then

area of Δ ABC = 20 - 4 $\frac{1}{2}$ - 4 - 2 $\frac{1}{2}$ = 20 - 11 = 9 units²
