Cloud [144]

Answer: x=15

Step-by-step explanation:

Equation: 107=(9x-115)+(4x+27)

Step 1: 9x+4x-115+27=107

Step 2: 13x-115+27=107

Step 3: 13x-88=107

Step 4: 13x-88+88=107+88

Step 5: 13x=195

Step 6: 13x/13=195/13

x=15

If you take half my age and add 7, you get my age 13 years ago. How old am I?
mestny [16]

Answer:

You are currently 40 years old

Step-by-step explanation:

Let's say the current age is represented by the variable x.

x = current age

The question says that "if you take half my age and add 7, you get my age 13 years ago"

This can be represented like this:

1/2(x) + 7 = x - 13

Now we solve for x using basic algebra:

1/2(x) = x - 20

-1/2(x) = -20

x = 40

To check if this is correct, plug it back into the equation and see if both sides equal each other:

1/2(40) + 7 = (40) - 13

20 + 7 = 27

27 = 27

Hope this helps (●'◡'●)

Megan made a paper chain that was 4m long. Mason’s chain was 479 cm long. Who’s was the longest? By how much?
Mekhanik [1.2K]

Answer:

Look below

Step-by-step explanation:

Let's start by converting 4 m into cm:

4m * \frac{10^{2}cm}{1m}= 4*10^{2}cm=400cm

Since Megan's chain is only 400 cm long, Mason's chain is longer by 79 cm.
