Question

Write a variable expression for a number q decreased by 7

Answer 1

Hey there!
We're going to be writing an expression, which means there's no equals sign, and no values are being compared or set equal to each other.
When we say decreased by seven, we really mean you're subtracting seven from that quantity because to decrease is to take away.
Therefore, if we have our number q decreased by seven, we have:
q - 7
Hope this helps!

Answer 2

Hey there,

The expression would be: q-7

Hope I helped :)
