Step-by-step explanation:

Answer:

The shorter piece is 4 in. long.

Step-by-step explanation:

The length of the shorter piece can be represented using x.

Thus, you can say that the longer piece is 2x (since it is twice as long as the other piece).

Since, the length of both the pieces will, for sure, add up to 1 ft, then we can say:

x + 2x = 1 ft

Which will simplify into:

3x = 1 ft  (Divide both sides by 3)

x = 4 in. (Since 1 ft = 12 in., we can express it in different units unless you want a non-terminating decimal)

x = 4 in. is the length of the shorter piece since we established that x is the length of the shorter piece earlier on.

Natalija [7]
Answer: It took 18 Months for Michelle to collect 59 dolls.


Explanation:
First, let’s right an equation for this. Michelle started with 5 dolls in a bar collection (I have no clue what that is but i’ll roll with it), and each month she bought 3 more, so 5 dolls plus the 3 dolls per month equals 59 at some point.

5 dolls + 3 dolls per month = 59 dolls
OR
5 + 3m = 59

The point of this question is to find how many months (m) it took in order to get to 59 dolls and there’s multiple ways you can do this:

1) just plug in random numbers into m to see how long it takes to get to 59 [this option might take a while]

2) Try to isolate m (get every number out of the equation) to find out the value of m. [I’m most familiar with this way]

First, subtract 5 from 5 in the equation in order to get rid of it, since we’re trying to get all whole numbers out of the equation and only have m left. You subtract 5 from 59 since the equal sign is kind of like a mirrror, whatever you do to one side you have to do to the other. So, 5-5 is 0, and 59- is 54.

Now you’re left with 3m=54. In order to isolate the m, divide 3 by 3 to get rid of the 3, then divide 54 by 3, which is 18.

In order to check your work, plug 18 into m just to see if it works or not:

5+3m=59 —-> 5+ 3(18)= 59

3 times 18 is 54, plus 5 is 59. So, Mi hells took 18 months to collect her 59 dolls. Hope this helped!

-2x = -34

x= -34/-2
