Question

Evaluate 7xy ÷ w + 4z when w = 10,x = 2,y = 5, and z = 9

Answer 1

First,, we need to insert the numbers in before we can start solving. This will change the expression to the following:
7(2)(5) ÷ 10 + 4(9)
We are first going to begin solving this by calculating the expression 7 × 2 × 5 ÷ 10. We can start this solving this by multiplying 2 by 5.
7 × 10 ÷ 10
Any expression divided by itself equals 1,, so the expression changes to:
7 × 1 
Any expression multiplied by 1 remains the same,, so add 7 back into the equation.
7 + 4 × 9
Multiply the numbers together.
7 + 36
Lastly,, add the numbers together to find your final answer.
