Answer:
17
Step-by-step explanation:
These two angles add up to 180, so we can set up an equation. 5x-23+7x-1=180. Now we combine like variables, getting 12x-23-1=180. We add 23 to both sides, and get 12x-1=203. Then we add 1 to both sides, getting 12x=204. Finally we divide by 12 on both sides, with our result as x=17.
Answer: 87.5%
Explanation: Since Janice answered correctly 21 questions out of 24 questions, you would divide 21 from 24
21/24 = 0.875
0.875 as a percentage would mean moving the decimal point two places to the right as 87.5%
Answer:
566
Step-by-step explanation:
We can solve this equation using PEMDAS, first solving the exponent.
24^2 = 576
Now we can move onto the subtraction
576 - 3 = 573
573 - 7 = 566
Answer:
is there an equation for this or simple math?
