Part A: 680-960d= 52,000
Part B: Answer $54.875
Do inverse operation
Add 680 to both sides
Then divide 960 to both sides
-32 = 4c -12
add -34 by 12 which is -20
divide it by 4
c = -5
Answer:
700 teens
Step-by-step explanation:
If five out of 7 teens do homework every night
There are 980 teens
How many out of 980 teens would do homework every night?
Firstly divide 980 teens by 7
Which is 980/7=140
Next is,
Out of 7 teens, there are 5 who do homework every night
So, multiply 140 by 5
140×5=700 teens
This means, the reasonable prediction of teens who do homework every night out of 980 is 700 teens
