X=grams of protein you need daily.
Remember (4%=4/100=0.04).
x=4% of x + 48 g
therefore, we can suggest this equation:
x=0.04x+ 48
x-0.04x=48
0.96x=48
x=48/0.96
x=50
Answer: 50 grams of proteins you need daily.
Other method:
the remaning is equal to =100%-4%=96%
Therefore: 96% of x=48
Remember (96%=96/100=0.96)
we can suggest this equation too.
0.96x=48
x=48/0.96
x=50
Answer:50 grams of proteins you need daily.
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!
