Let's set up a proportion.
3/20=x/100
Because 20*5=100, you can determine x by multiplying the numerator by 5 as well.
3*5=15
x=15
15%
Answer:
x = 20
Step-by-step explanation:
The angles that are marked are called "vertical angles" (I think of a pair of scissors) The two angles are equal to each other. (They get bigger or smaller together, like a pair of scissors)
So, set them equal to each other and solve.
3x + 50 = 6x - 10
SUBTRACT 3x from both sides.
50 = 3x - 10
ADD 10 to both sides.
60 = 3x
DIVIDE both sides by 3.
20 = x
I think it’s 18 and I will explain how I got that
Explanation: so first I added all the marbles she took out to see the total she took out which was 50 and if she did it 90 times I need to see how much time 50 she did it more and that was so 90 divided by 50 is 1.8 and that times 10 (times because we want to see how many times the red marble would come out) and that’s 18
