So first you have to do PEMDAS (Parenthesis, Exponent, Multiply, Divide, Add, Subtract). Now, when you do PEMDAS, you need to go from left to right in the order I just described to you.
So in this situation, first multiply 5 times 3 to get 15. Next is addition. 15+4=19.
PS sorry for taking so long.
You cant parentheses in that sentecne
Do 12 2/3+10 2/3 which is 23 1/3 than subtract 8 2/3 for your answer.
Answer:
(#14 - supplementary) x = 10.5
(#15 - supplementary) x = 10
Explanation:
For these problems, we must know that a supplementary angle can be viewed as a sum of angles that add to 180 degrees. With this known, we can write our equations to find x.
(#14)
15x - 12 + 5x - 18 = 180
20x - 30 = 180
20x = 210
x = 10.5
(#15)
6x + 13 + 14x - 33 = 180
20x - 20 = 180
20x = 200
x = 10
Hope this helps.
Cheers.
