Answer:
18 boys
Step-by-step explanation:
we add 2 and 3 because they are equal parts:
2+3=5
Then we divide 45 by 5 because we want to find what 1 part equals"
45/5=9
We now do 9*2 to get an answer of:
9*2=18
hope this makes sense!
Answer: 2x - 30
then x = 2.
4 multiplied by 2 = 8
8 divided by 2 equals 4
Putting it together:
4(2)/2=4
