Santa has many toys to deliver on Elm Street. If there are 48 kids that live on Elm
kobusy [5.1K]

Answer: 3 : 1

Step-by-step explanation:

We know that there are 48 kids in Elm street.

12 of them are boys, then the number of girls will be:

48 - 12 = 36

So there are 12 boys and 36 girls.

Then the ratio of girls to boys is 36:12

We can divide both numbers by the same number and we will get an equivalent ratio, if we divide by 12 in both sides, we have:

36/12 : 12/12

3 : 1

Then the ratio is 3 to 1.

If x/2+ 7 = 4<br> , what is the value of 5x - 7?
horrorfan [7]

Answer:

-37

Step-by-step explanation:

for the first equation to equal 4 the x must equal -6.

because something plus 7 had to equal 4. and we know that -3 + 7 equals 4. Now, -6 ÷ 2 equals -3 and that gives us the right answer.

So now plug -6 into the new problem so now it is

5 × (-6) - 7 so according the PEMDAS, we do 5 × -6 first which is -30. and -30 - 7 equals -37!!

hope this helps :)
