10x + 16 + 54 = 90

10x + 70 = 90

Answer:

Step-by-step explanation:

We know that these angles HAVE to add up to 90°.

First lets eliminate the extra number (16). To do so, we just need to add it to 54.

54 + 16 = 70

Now there is 20 degrees missing.

So we just need to divide 20 by 10

20 ÷ 10 = 2

So 2 is the answer

The height of a stack of 12 pennies is 18.24 millimeters. What is the thickness of each penny.

Helga [31]

I’m not great at math so I could easily be wrong, but

I divided the 18.24 millimeters by 12 pennies and got 1.52

So if the pennies are all the same size, each penny should 1.52 millimeters.

To show work:

18.24/12=1.52
