Answer:
4
Step-by-step explanation:
Substitute -3 for x.
-3 + 7 = 4
make improper fractions first. Then look for a common denominator (7*9) you will get something like this:
((73*9 + 9*19*7)/(63))
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.
$6.75 + $4.25 = $10.00
$15.95 - $10.00 = $5.95
The answer is $5.95
