Answer:

Step-by-step explanation: PEMDAS is an easy way to remember the order of operations. In the image provided, I attached what the letters actually mean so you can take a look at that.

I'll show an example of a problem using PEMDAS.

8 + 2 × 3

The first thing you need to know about the order of operations is that multiplication and division always come before addition and subtraction.

So in this problem, we will multiply before we add.

Since 2 × 3 is 6, our next step will read 8 + 6 which simplifies to 14.

Salsk061 [2.6K]

<u>Statement:</u>

Two angles are supplementary. One angle measures 2x, and the other angle measures 3x - 15.

<u>To </u><u>find </u><u>out:</u>

The equation to find the measure of each angle.

<u>Solution</u><u>:</u>

  • Supplementary angles are angles which sum up to 180°.
  • While, complementary angles are angles which sum up to 90°.
  • Here, the sum of the two angles, i.e., 2x and 3x - 15, should be 180°.
  • So, the equation will be: 2x + 3x - 15 = 180°.

<u>Answer:</u>

2x + 3x - 15 = 180°

Hope you could understand.

Answer:

x= 8

Step-by-step explanation:

(17x + 14)+(4x - 2) = 180

21x + 12 = 180 : add like terms

21x = 168 : subtract 12 from both sides

x = 8 : divide by 21 to get x alone
