Y= 42. 3(3+7)+12
3(10)+12
30+12
42
y=42
Answer:
1)
2x = 16
16 ÷ 2 = 8
x = 8
2)
2 + x = 28
28 - 2 = 26
x = 26
3)
3 ÷ 6 = 0.5 (I'm not sure about this one)
4)
27 - 10 = y
27 - 10 = 17
y = 17
5)
1/3 = 400 cal
400 + 400 + 400 = 1, 200
whole pizza = 1,200 calories
6)
$287 - $175 = $112
Answer:
Im going to use the Pythagorean theorem.
a^2+b^2=c^2
Line AB is A, line CB is B, and line AC is C.
4^2+2^2=c^2
4^2=16 and 2^2=4
16+4=20^2=4.5
4.5 shoudl be your answer.
