63.8, subtract 24.2 from 90 to get your answer since complementary means 90 degrees and supplementary means 180 degrees. Hope this helped! :)
18 students are 100%-37,5%-40%=22,5%
So we know that 18 students equal to 22.5. And we are looking for the anwser what 100% of students is.
SO:
x students - 100%
(22 + 1/2)x =18×100
(22 + 1/2) can be represented as just 25.5
-//- = 1800
we need to divide bot sides by 25.5
x = 1800 / 25.5
... x = 80
79 percent i believe hope this helps
Answer:
b=1
Step-by-step explanation:
<u>First, let's regroup, terms,</u>
<u>Add 11 to both sides,</u>
<u>Simplify, 7+11 = 18,</u>
<u>Now, divide both sides by 3,</u>
<u>Simplify, 18/3 = 6,</u>
Subtract 5 from both sides,
Hope it helps! :)
