Answer:
672
Step-by-step explanation:
a+b / 2 times h
They are vertical angles, thus they are equal to each other:
5x + 12 = 6x - 10
22 = x
x = 22
Answer:
Petra would need to save for 12 weeks to get 126
126+34.75=160.75
3(n - 5) = 24
Distributive property
3*n = 3n
3*5 = 15
3n - 15 = 24
+ 15 +15
3n = 39
3n/3 = 39/3
x = 39/3
x = 13
Answer: x = 13
1/3 x 4/4 = 4/12
4/12 + 5/12 = 9/12
12/12 - 9/12 = 3/12
3/12 = 1/4
