X is Maggie's age
y is the brother's age
x+y=24
y=2x-3
Use substitution method
x+(2x-3)=24
3x-3=24
3x=27
x=9
Maggie is 9. (Her brother is 15)
Answer:
A.) 101
B.) 121
Step-by-step explanation:
If two angles are supplementary, that means they add up to 180 degrees. If you have an angle, and want to find it's supplement, you would subtract the given angle from 180.
180 - 79 = 101
180 - 59 = 121
Hope this helps!

I dont need brainliest
Brainley patrol took down my question :(
Answer:
a) m∠3=113°
b) x=8 (but check below)
Step-by-step explanation:
a) we know m∠1=m∠5
6x-5=5x+7
x=12
we also know m∠1+m∠3=180°
plug x into the formula for m∠1
m∠1=67
m∠1+m∠3=180°
67+m∠3=180°
m∠3=113°
b) Again, we know since those lines are parallel that m∠4=m∠8
x²-4x=32
x²-4x-32=0
(x-8)(x+4)=0
x=8 or x=-4
i think (not 100% sure about this part lol) but x cannot be negative so it's 8
again i'm not sure but it is either 8 or 8,-4.
How u solve it is you follow you signs and you go step by step and you will have your answer if that makes sense
