Answer: Michael is 72.
hope this helps
Step-by-step explanation:
Let Brandon be b. Then Michael is 3g.
3g-18=9(b-18)
3g-18=9g-162
6g=144
b=24
3g=72
So to solve for y, we need to get y alone on one side of the equation. So we are going to subtract 9x from both sides of the equation to get:

And since y is negative, we are going to divide both sides by -1 in order to make the y positive:

5(1+9v) = 5+ 45v
20b+12= 4(5b+3)
And the last one is r=2

Answer:
102,100 decigrams
Step-by-step explanation:
(564 dag + 458 dag) = 1021 dag
1021 dag × 100 dg/dag = 102100 dg
