Hey there!

Let's write this as a system of equations.

m+b=22

b= 4m-3

Let's plug our value for b into the first equation and solve for m.

m+4m-3=22

We combine like terms.

5m-3=22

We add 3 to both sides.

5m=25

We divide both sides by 5.

m=5

Therefore, Maggie is 5 years old.

I hope this helps!

It is A. 2^12.
The question asks for the value of 8 to the x-power. Divided by 2 to the y-power. the trick to solving this is to rewrite 8^x as 2^3x. so you will have 2^3x divided by 2^y. since the bases are now the same , you can subtract the exponents to get the result of 2^3x-y. since it is given the 3x-y is 12. your final answer is 2^12
