Answer:
18
Step-by-step explanation:
The ~ indicates that ∠ABC is similar<em> </em>to ∠QRS. In other words, their proportions are the same, even if their size is different.
So AB has the same proportions as QR. 4 can be multiplied by 2.25 to get to 9. So multiply 8 by 2.25 to get n.
8 * 2.25 = 18 so n = 18
10^-8 because e-8 is 10^-8
You may express it as :
-18+24x+5x-40=8-20x
49x=56
x=56/49
By substitution is how to solve
2x-3y=21
y=3-x
2x-3(3-x)=21
2x-9+3x=21
5x=30
x= 6
now substitute our x value into y=3-x
so we get
y=3-6 = -3
so x=6 and y=-3 hope this helps!!!!! Thank you!
Answer:
2x + 3y - 24 = 0
Step-by-step explanation:
2x + 3y = 18
3y = -2x + 18
y =
x + 6
m = -2/3
y - 4 = -2/3(x - 6)
3y - 12 = -2x + 12
2x + 3y - 24 = 0
