Answer: 3/4x - 3

Step-by-step explanation:

Let his sister's sale be represented by x.

Since we are informed that Keiko sold 3 less than three-fourths of his sister's sales, the expression that represents what Keiko sold will be:

= (3/4 × x) - 3

= 3/4x - 3

What is the answer to thiss

Hi Student!

This question is fairly simple because it gives us an equation and they also give us a value for the variable that is within the equation and they tell us evaluate the expression. So let's plug in the values and solve.

Plug in the values

$m^2 + 5$

$(9)^2 + 5$

Factor out the exponent

$(9*9) + 5$

$81 + 5$

Combine

$86$

Therefore, the final answer that we would get when substituting m with 9 in the given equation is that we get 86.
