Joe is taking part in a run for charity. He has earned $250 in pledges just for running and $40 in pledges for every mile he run

Harlamova29_29 [7]

im in middle school taking algebra 1 rn, but im pretty sure the equation is similar to 40x(40 pledges every mile) + 250(how much he already has from running) = y(the unknown variable).

so the equation would be 40x+250=y and you solve that to get the expression of how much he makes per mile

3 over the power of 2 multiply by 3 over the power of 5

Nostrana [21]

Answer:

$3^2 \times 3^5 = 3^7$

3^2 * 3^5 = 3^7

Step-by-step explanation:

I assume you mean this:

$3^2 \times 3^5$

If so, then the rule is that when you multiply two numbers with the same base, you give the same base and add the exponents.

$3^2 \times 3^5 = 3^{2 + 5} = 3^7$
