Sawyer owns a bicycle shop. During one week, he sells b bicycles for

mihalych1998 [28]

To find the total revenue for any object, you simply multiply the price of the object by the number of units sold.

In this case, the revenue for helments would be 3*14, and the revenue for bicycles would be 125*b.

Knowing that total revenue was 917, we can form an equation:

125b + 3*14 = 917

125b + 42 = 917

Subtract both sides by 42:

125b = 875

b = 7

Sawyer sold 7 bicycles

Check my work 3(x+1)-8=14-2(3x-4)

jeyben [28]

The value of x is 3

Step-by-step explanation:

Equation:

3(x+1)-8=14-2(3x-4)

1. Open the brackets

3(x+1)-8=14-2(3x-4)

3x + 3 - 8 = 14 - 6x + 8

2. Bring all x variables on the left side

3x + 6x = 14 + 8 + 8 - 3

3. Solve

9x = 27

x = $\frac{27}{9}$

x = 3

Therefore, the answer of x is 3.
