To find the percentage always multiply whatever decimal number you have by 100% <span>
1) 5 + 8 + 12 = 25 (total number in bag)
5/25 x 100% (because you're trying to find probability of red)
= 20%
2) 5 + 8 = 13 (# of red AND blue)
13/25 x 100% (divide out of the total)
=52%
3) 5/25 = 0.2 x 12/25 = 0.48 (find probability of drawing red and green)
0.2 x 0.48 x 100%
= 9.6%
4) 10 + 12 + 28 = 50 (to find total number of trials)
28/50 x 100%
= 56%
5) 5 x 7 (number of sections on first spinner multiply by # of sections on second spinner)
= 35</span><span>Its B 20%

Answer:
x = 5
Step-by-step explanation:
(2x - 1) / 9 = 3x / 15
Cross multiply
9(3x) = 15(2x - 1)
Distributive
27x = 30x - 15
Subtract 30x from both sides
-3x = -15
Divide by -3 on both sides
x = 5
The altitude of a shape or a polygon can be determined by drawing a perpendicular line from the base to the top most part of the polygon. In this case, the altitude is the segment BC where the ends are on the topmost of the cylinder and the base of the cylinder.
Solve for x:
Take the root of both sides and solve.
All real numbers Interval Notation
(-infinity, infinity)
(Don’t actually write infinity, write the infinity symbol)
X/3 > 7 <== ur equation
multiply both sides by 3
x > 7 * 3
x > 21 <== ur solution
