Maya is making dream catchers with her family. Each dream catcher takes 1.53 feet of string. She has 6 people in her family. How much string does Maya need total?

1.53*6=9.18

You know where to put the decimal because you count how many places in the decimal is for the two numbers being multiplied (the only decimal in the two numbers being multiplied is in the number 1.53 and that’s is two places in) and then go that many places in on the product (918 two places in from then right would be 9.18)

N- 0.125= 4.1 what is N?
guajiro [1.7K]
Well, lets add 0.125 to 4.1.

We would get 4.225.

Finally we can check.

4.225-0.125= 4.1

How did we get it? What i did is I did the opposite. Instead of subtracting 0.125 I added it.

N= 4.225

Four gallons of gasoline weigh 25 pounds . find the unit rate in pounds per gallon.
notka56 [123]
There are several information's that are already given in the question. Based on those information's the answer to the question can be easily deduced. 
Weight of 4 gallons of gasoline = 25 pounds
Then
Weight of 1 gallon of gasoline = 25/4 pounds
                                                = 6.25 pounds
From the above deduction, we can easily conclude that the unit rate in pounds per gallon of gasoline is 6.25 pounds/gallon. I hope the answer helps you.

Answer:

4,096

Step-by-step explanation:

It goes like this 4 * -4=-16, 16*4=64, -64*4=256, etc.

You use the sum of the last number but flip the sin to make it opposite like if your some was + make it a negative to get your next product. Hope that made sense!!!!
