Answer:
9.4 + p = 4.8
9.4 + p - 9.4 = 4.8 - 9.4
p = -4.6
Answer:
4:5
Step-by-step explanation:
If there are 12 boys and 15 girls, the ratio of boys to girls will be 12:15.
However, this can be simplified by dividing each number by 3. This can be done since both 12 and 15 are divisible by 3.
12:15
= 4:5
So, the ratio of boys to girls in Timara's class is 4:5
Answer:
Step-by-step explanation:
we know that
The expression Subtract 
from 
is equivalent to the algebraic equation
Group terms that contain the same variable
Combine like terms
R + d = 1750
r = d + 450
d + 450 + d = 1750
2d + 450 = 1750
2d = 1750 - 450
2d = 1300
d = 1300/2
d = 650 <=== what Dustin pays
r = d + 450
r = 650 + 450
r = 1100 ...Robert pays 1100
The probability it will take 20 minutes or more is about 6.3%.
