Answer:
1 cubic meter equals 1000 liters
Step-by-step explanation:
i think this is right
-15v-40=23-8v
We're trying to isolate the v so...
1) -15v= 63-8v add the 40 on both sides
2) -7v=63 add the 8v on both sides
3) divide -7 on both sides to solve for v
4) v= -9
Answer: x=2
Step-by-step explanation:
Expand
8x−24x+16=−6−5x
simplify
−16x+16=−6−5x
add 16 to both sides
16=−6−5x+16x
simplify
16=−6+11x
regroup the terms
16=11x−6
add 6 to both sides
16+6=11x
simplify
22=11x
divide
22/11=x
simplify
2=x
switch sides
x=2
Answer:
20 mins.
Step-by-step explanation:
A babysitter charges a rate of $15 per hour. How long was the babysitter there if she makes $5?
x = hours she babysat
Equation:
15x = 5
Divide to isolate x:
15x = 5
/15 /15
x = 1/3 hrs.
Now, we convert into minutes, since she didn't work for a whole hour, to earn the $15
We know that there are 60 mins. in an hour
60 * 1/3
60/3
20 mins.
Therefore, the babysitter was there for 20 mins.
Hope this helps!
