Mr. Anders was three times as old as Kate 5 years ago. Their total age now is 42 years. How old is Kate now?
katrin [286]
We can write this as two equations. Call Mr. Anders' age A and Kate's age K:
A-5=3(K-5)
A+K=42

Then solve for A in the second equation:
A=42-K

Substitute this into the first equation:
(42-K)-5=3(K-5)
-K+37=3K-15
52=4K
K=13

A ratio of boys to girls in the classroom is 4 to 5 if there are 20 girls how many boys would there be
Viktor [21]

Answer:

16 to 20

Step-by-step explanation:

Let's do our math.

4 to 5

8 to 10

12 to 15

16 to 20

In order to get to 20, you'd have to multiply 5 by 4. So in order to get an equal ratio, you multiply 4 by 4 and get 16.

I hope this helps!

Number 4 is C because when you do 28 times 5 your get 140 then you do 140 divided by 20 to get 7 when you do proportions to find the missing number you cross multiply with the numbers there and divide with the number that is across from the missing
Number 5 is $6 because to find the missing number you have to see which way makes sense you could do 4 divided by 3 but you get a really long number so if you do 3 divided by 4 you get .75 and you get .75 for all cost is usually the y-axis so you do y divided x so then do .75 times 8 to get the answer
Number 6 to plot them you just go in the middle of the line for the first because it is not directly 2
Number 7 to change a fraction to decimal do the numerator divided by denominator even if the denominator is bigger so 6 divided by 25 is .24 for decimal form to get the percent move the decimal point two places to the right so it will be 24%
