artcher [175]

Answer:

14(y + 2).

Step-by-step explanation:

32 +2/3(21y - 6)

Distributing the 2/3 over the parentheses:

= 32 + 2/3*21y + 2/3 * -6

= 32 + 14y - 4

= 14y + 28

= 14(y + 2).

Americans who are 65 years of age or older make up 12.9% of the total population. If there at 30.3 million american in this age

telo118 [61]

Total population of US is 234.88 million.

Step-by-step explanation:

Given,

Number of people are 65 or older = 30.3 million

This represents 12.9% of total population.

Let,

x represent the total population.

12.9% of x = 30.3 million

$\frac{12.9}{100}x=30.3\ million\\0.129x=30.3\ million$

Dividing both sides by 0.129x

$\frac{0.129x}{0.129}=\frac{30.3}{0.129}\ million\\\\x=234.88\ million$

Total population of US is 234.88 million.

Amal and Salma share some money in the

Oksi-84 [34.3K]

$315, i cant give a thorough explanation since i did it all in my head but basically amal gets 5 portions of the money and Salma gets 9, meaning she gets 4 more, so if 4 portions is $252 then it cant be any of the others since they are too low or way too high, $315 is the only reasonable one.

Ms. Wilson invested $34000 in two accounts, one yielding 8% interest and the other yielding 9%. If she received a total of

Digiron [165]

Answer:

Amount invested at 8 % rate = x = $ 15000

Amount invested at 9 % rate = 34000 - x = 34000 - 15000 = $ 19000

Step-by-step explanation:

Total Amount = $ 34000

Let amount invested at 8 % rate = x

Amount invested at 9 % rate = $ 34000 - x

Total interest = $ 2910

$2910 = \frac{x (8) (1)}{100} + \frac{(34000-x) (9) (1)}{100}$

291000 = 8 x + 306000 - 9 x

x = 306000 - 291000

x = 15000

So amount invested at 8 % rate = x = $ 15000

Amount invested at 9 % rate = 34000 - x = 34000 - 15000 = $ 19000
