Percent means parts out of 100
85%=85/100=0.85
'of' means multiply
therefor
85% of x equals 17 means
0.85 times x=17
divide both sides by 0.85
x=20
the number is 20
Answer:
Step-by-step explanation:
There are several words that might well fit this sentence:
"supplemental"
"entrepreneural"
"earned"
1. To find the square root, you have to square root them both.
Square root of 324 is 18, so x=-18, 1818
2. Divide 49 by 9. 49/9=5.44 then find the square root of 5.44 which is 2.3, x=-2.3, 2.3.
3. To do this one it is one of either 2 or 4 because it is not a perfect square, it can break down to square root of 16 and square root of 6, which then makes it +-4 square root 6.
4. This one is simple the square root of 34 is 5.8
5. Subtract each by 5 to get 6y^2=215 then divide each by 6. Y^2=34.8 then square root. Which makes y=+-5.9. Hope this helped.
The Answer is 8. B 18 is D
B is the correct answer i believe
