5(x + 2) + 6(x - 3) = 25

Simplify.

5x + 10 + 6x - 18 = 25

Add like terms.

(5x + 6x) + (10 - 18) = 25

Simplify.

11x - 8 = 25

Add 8 to both sides.

11x = 25 + 8

Simplify.

11x = 33

Divide both sides by 11.

x = 3

~Hope I helped!~

Perimeter of a triangle = add all sides

Both the legs of the isosceles triangle are always EQUAL.

Three people split an amount of money. 1 268 dollars and 1 gets 200 dollars. The third gets 40 percent. What is the amount?
Maksim231197 [3]

The total amount is $ 780

<em><u>Solution:</u></em>

Let the total amount be "x"

Given that,

First person gets $ 268

Second person gets $ 200

Third person gets 40 %

This means, third person gets 40 % of total amount

Third person = 40 % of x

Third\ person = 40 \% \times x\\\\Third\ person = \frac{40}{100} \times x\\\\Third\ person = 0.4x

We know that, total amount is equal to sum of amount got by all three persons

Total amount = first person + second person + third perosn

x = 268 + 200+ 0.4x\\\\x - 0.4x = 268 + 200\\\\0.6x = 468\\\\x = \frac{468}{0.6}\\\\x = 780

Thus the total amount is $ 780
