Question

Complete each expression to

make its value equal to 9
(24 - ?)=2
29-(?x 5)
?(2 x 3)

Answer 1

The first unknown value is 6.

The second unknown value is 4.

The third unknown value is 54.

Explanation:

Step 1:

To determine the unknown values, we assign variables to each expression.

Assume the first unknown value is x, the second unknown value is y, and the third unknown value is z.

We solve the expressions for x, y, and z.

Step 2:

Since all the expressions equal 9, we substitute the values with 9 on the RHS.

`(24-x)/(2) =9.`

`24-x = 2(9) = 18.`

`-x = 18-24 = -6.`

`x=6.`

`29-(5y) = 9.`

Step 3:

`-5y = 9-29=-20.`

`y= (-20)/(-5) = 4.`

`y=4.`

`(z)/(6) =9.`

`z = 54.`

So the unknown values are 6, 4, 54.
