set up a ratio to find the length:
15/12 = DE/16
cross multiply the 15 & 16:
15 * 16 = 240
divide that by 12 to get DE
240 / 12 = 20
DE = 20
5*4*6=120
4+(6+9)=19
675+9=75
Answer:
3p+10=28
-10 -10
3p=28-10
3p=18
p=18/3
p=6
Step-by-step explanation:
Answer:
40 minutes
Step-by-step explanation:
You can simply make 200/5 = 40 5 minute calls per month.
This works because every call is a 5-minute call. So then we just have to find how many times we can make a 5-minute call up to 200 minutes. We already have an operation for this: Division. This acts as the opposite of multiplication and speeds our process up.
I don't know if this will help but the 2 on the right are not parallelograms there
