Answer:
1514
Step-by-step explanation:
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:
Before going to the bakery, Lisa had more than $32.40.
Step-by-step explanation:
Hi there!
Let x be Lisa´s savings.
She brings half of her savings to the bakery and expends $14.20. What is left is more than $2.00. Then:
x/2 - 14.2 > 2
Let´s solve the inequality:
x/2 - 14.2 > 2
Add 14.2 to both sides of the inequality.
x/2 > 2 + 14.2
x/2 > 16.2
Multiply by 2 both sides of the inequality.
x > 32.4
Before going to the bakery, Lisa had more than $32.40.
-5, work backwards. you know 2 + 4 * ? = -18.
start by subtracting 2 from both sides giving you 4 * ? = -20.
now you divide 4 from both sides giving you ? = -5
i used ? to represent the missing number btw!!
