12(1-x) = 36<br> what’s the equation
maks197457 [2]

Answer:

-12x + 12 = 32............................. the equation

Step-by-step explanation:

to determine the equation in this 12(1-x) = 36 expression is quite simple, you only need to open the bracket .

solution

12(1-x) = 36

12 - 12x = 32

-12x + 12 = 32............................. the equation

we  can further evaluate for the value of x  

-12x = 32 - 12

-12x = 20

divide both sides by the coefficient of x which is -12

-12x = 20

-12x/-12 = 20/-12

x =  -1.67

Alicia earned d dollars baby-sitting. Her friend earned twice as much. You earned $2 less than Alicia's friend earned. Write an
Semenov [28]

Answer:

Total = \$5d - 2

Step-by-step explanation:

Represent Alice with A, her friend with F and you with Y.

From the question, we have:

A = \$d

F = 2 * A --- Twice as much Alice means 2 times Alice's earnings

Y = F - 2 --- 2 less than her friend

Required

Determine the total amount

A = \$d

Substitute \$d for A in F = 2 * A

F = 2 * \$d

F = \$2d

Substitute \$2d for F in Y = F - 2

Y = \$2d - 2

The total amount is calculated by adding the earnings of Alice, her friend and you

Total = A + F + Y

Total = \$d + \$2d + \$2d - 2

Total = \$5d - 2

<em>Hence, the total earnings is 5d - 2</em>
