Answer:
1010
Step-by-step explanation:
There are a whole class of questions that rely on the method to this one.
First add up what you know
1270 + 1150 + 870 + 1450 = 4740
Now add on the 5th month (which you don't know. Call it x)
4740 + x
Divide by 5
(4740 + x)/5 = 1150 and that is your equation
Solution
Multiply both sides by 5
5*(4740 + x) / 5 = 1150 * 5
4740 + x = 5750
Subtract 4740 from both sides
4740 - 4740 + x = 5750 - 4740
x = 1010
Which seems kind of low, but that's what the numbers come to.
A+(-1.3)=-4.5
Add 1.3 to both sides of the equation
a=-3.2
Answer:
A does not have any proportional relationship.
Step-by-step explanation:
All of the other tables have obvious relationships, leaving A to be the answer.
36 divided by12 is three
so the answer is $3 dollars per month
