Question

What is the value of the expression below when w=4 and x=2 ? 8w-5x

Answer 1

Answer: 12

Explanation:

So we have our equation 8w-5x

We know that w=4 and x=2

8w is the same as 8 times w and 5x is the same as 5 times x

w=4 so 8 times 4 is 32

x=2 so 5 times 2 is 10

32-10=12

Your answer is 12

Answer 2

Answer: 12

Explanation:

We need to calculate the value of the expression when w = 4 and x = 2.

So what we do is we substitute these values into the expression, and simplify:

8w - 5x {given expression}

8(4) - 5(2) {multiply}

32 - 20 {subtract}

12

Therefore, the value of this expression is 12.
