Iam thinking of a number. multiplying it by 7 and adding 2 is equal to multiplying it by 2 and adding 7. what is the number?

The number you are thinking is 1

Solution:

Let the number you are thinking be = x

Multiplying the number by 7 = 7x

Adding the number 2 = 7x + 2

Multiplying the number by 2 = 2x

Adding the number 7 = 2x +7

Both these equation are equal to one another

7x + 2 = 2x + 7    

Simplify the equation,    

7x - 2x  = 7 - 2    

5x = 5

x = 1

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units

step-by-step explanation:

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
