mafiozo [28]

Answer:

9 months

Step-by-step explanation:

$500 - $240 = $260

$260/$30 = 8.67(3s.f.) ≈ 9 months

Recheck:

Balance after 9 months = 240 + (30×9) = 240 + 270 = $510

                                      ∴ $510 > $500

Which One Doesn't Belong?<br> 3x - 5<br> 12x<br> 1 + x<br> x2 + 5x + 6
lesya692 [45]
3x-5 does not belong

Reasoning :

Plug in “1” to each X unit

3(1) -5 = -2
12(1) = 12
1 + (1) = 2
(1)2 + 5(1) + 6 = 13

all are positive except 3x-5

so 3x-5

One serving of granola provides 4% of the protein you need daily. You must get the remaining 48 grams from other sources. How ma
Inessa [10]
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.
