Let,
the no. of adults be "x"
then, the no. of childern = total people - total adults
= (30 - x)
Now,
According to the quesiton,
2 (30 - x) + 5x = 87
60 - 2x + 5x = 87
60 + 3x = 87
3x = 87 - 60
3x = 27
x = 27 / 3
x = 9
So, there were 9 adults in the group
we are given
Since, we have to solve for b
so, we will isolate b ony one side
so, we will add 60 on both sides
so,
Answer:
Maureen should have added 60 to both sides.
Answer:
You can only simplify it down to -6y+1
Step-by-step explanation:
Since there is nothing past the equals sign, there is no way to solve it, only a way to simplify it. Hope this helps!
<span>I know because 2:3 is the ratio for the first and when he gets 9 that is 3* more. So we multiply 3*2 of the red paint and we will get 6 </span>
Answer:
The second one
Step-by-step explanation:
x+6=2x (picture shows)
x=6 (algebra)
3x+1=19
2x+7=19
PQ=QR
