Determine the total number of markers
First, we need to determine the ratio of black to blue such that
Multiply the ratio by 5
By direct comparison:
The above shows that:
So:
Answer:it's 1/625
Step-by-step explanation:
You times the denominator 5 from 1/5 by 5 4 times to get 1/625
The answer that you should get is D
Answer:
together they have 60
Step-by-step explanation:
B= number of balloons billy has
A =adams balloons
Adam had 30 less balloons than Billy
A = B-30
After Billy gave 5 balloons to Adam, the number of Adam's balloons was half of the number of Billy's balloons.
1/2(B-5) = A+5
1/2 (B-5)-5 =A
set the two equations equal A = B-30 equal to 1/2(B-5)-5 = A
B-30 = 1/2(B-5)-5
add 5 to each side
B-30 + 5 = 1/2 (B-5)
B - 25 = 1/2 ( B-5)
multiply by 2
2(B-25) = 2* 1/2 (B-5)
distribute
2B-50 = B-5
subtract B
2B-50 -B =B-B -5
B-50 = -5
add 50
B-50+50 = -5+50
B = 45
Now we need to find out A
A = B-30
A = 45-30
A = 15
Billy has 45
Adam has 15
together they have 45+15
together they have 60
Answer:
A
Step-by-step explanation:
a^3 is a * a * a, b^2 is b * b, so we can write that in the numerator.
a^2 is a * a. So we can change that in the denominator.
The denominator cancels out with part of the numerator, and leaves us with just a*b, which is ab, which is answer A.
