Solve the equation using the inverse operation: x/4 = 12

Question

A). Inverse operation is multiplication; x = 48

B). Inverse operation is division; x = 48

C). Inverse operation is addition; x = 16

D). Inverse operation is subtraction; x = 8

Answer 1

To solve the equation \( \frac{x}{4} = 12 \) using the inverse operation, we need to multiply both sides of the equation by 4 (the inverse of division by 4):

\[ x = 12 \times 4 \] \[ x = 48 \]

Therefore, the correct answer is:

A). Inverse operation is multiplication; x = 48

Answer 2

Bill goes to the market to buy some apples. The cost of the apples that he likes is $1.25 per pound. If he has $5 to spend on apples, how many pounds (x) can he buy?

Set up an equation to solve the problem.

Answer 3

To determine how many pounds of apples Bill can buy with $5 when the cost is $1.25 per pound, we can set up the equation as follows:

Let \( x \) represent the number of pounds of apples Bill can buy.

The total cost of the apples can be expressed as: \[ 1.25x \]

Since Bill has $5 to spend, we can set up the equation: \[ 1.25x = 5 \]

To solve for \( x \), you can divide both sides of the equation by 1.25: \[ x = \frac{5}{1.25} \]

Calculating that gives: \[ x = 4 \]

So, Bill can buy 4 pounds of apples.
