julia saw 5 times as many cars as trucks in a parking lot. if she saw 30 cars and trucks altogether in the parking lot, how many were trucks?

How do u do this step by step

Answers

You need to use PEMDAS or the Order of Operation. P is parentheses, E is exponents, M is multiplication, D is division, A is addition, and S is subtraction. 8+5 is 13. There are No exponents or multiplication. Divide 13 by 1 and you get 13. So far, you have 1 + 13 - 3 - 13 + 4. If you do the addition you get 18 - 3 -13. 18 - 3 is 15. 15 - 13 is 2. Your answer is 2.

In a group of 48 children there are three times as many boys as girls. how many girls are there

Answers

if x=girls,
then we have 3x boys.

We know that all children are boys+girls, so x+3x, which is 4x and 4x is 48, so one x is 12.

So there are 12 girls and 36 boys.

There are x girls in the group.
There are three times as many boys as girls, so the number of boys is 3x.
There are 48 children in the group.

$x+3x=48 \n4x=48 \nx=(48)/(4) \nx=12$

There are 12 girls in the group.
