M=20
You isolate the variable by dividing each side by factors that don’t contain the variable
Answer:
area of the polygon=1/2×(28+18)×12
=276unit²
Y=4
Don’t judge if I’m wrong
Simplifies it would be 18.34-6y-6
Jason is buying 2 hats and 3 scarves for each of his 4 children
so he is actually buying 8 hats and 12 scarves.
a hat costs 8.50 and a scarf costs 5.50
so you put it into a equation
8.50(h)+5.50(s) = P h = hat, s = scarf, P = pay
8.50(8)+5.50(12) = P
68 + 66 = P
P = 134
hope this helps
2×+y=0,
×-y=6
Add the 1st to the 2nd equation==> 3x +y-y=6+0==> 3x=6 & x=2
Plug 2 into any of the equation & you will get y=-4
