Answer:
exact form: -17/8
decimal form: -2.125
mixed number form: -2 1/8
Step-by-step explanation:
cmon this is freaking addition
B) -8 + (-12)
Because you just have to use the distributive property and distribute -1 to (8+12)
<span>3(7 + 4)2 − 14 ÷ 7
First do the parenthesis
7 + 4 = 11
so the question looks like: 3(11)2 - 14/7
Then multiply 3, 11, and 2 together
3 x 11 x 2 = 66
66 - 14/7
14/7 equals to 2
66 - 2
Then just simplify
66 - 2 = 64
64 is your answer
