Answer:
y = 3x -31
Step-by-step explanation:
y=mx+b
m=3
5 = 3*12 +b
b = 5 - 36
b = -31
y = 3x -31
Answer:
B
Step-by-step explanation:
x+4 is double of 16 so multiply 16 by 2 then subtract by 4 to get x which is 28
Answer:
A little less than 5.
Step-by-step explanation:
An estimate means you should be able to do it in your head.
400/80 = 5 So the answer should be about 5
Can we get it a little closer? Maybe.
Divide 375 in your head by 25. It's about 15
Divide 80 by 25 which is about 3.2
15/3.2 It's under 5. but not by much. Only now can you use a calculator. The rounded answer is 4.6
For this question you want to take 83 and subtract 56 which would give you 27. So 33 couldn't be the number of cows still in the barn.
