Does anyone know the answer to this?

DENIUS [597]

Answer:

B

Step-by-step explanation:

-3/4y - 1/5y = 380 can be simplified to -19/20y = 380.

In order for the student to incorrectly get 361, they likely just multiplied the 380 by 19/20 rather than multiplying by the reciprocal (which would be -20/19).

This means the best answer should be B.

Terry goes to the store to buy a shirt. The original price is $32. The shirt is

Anton [14]

Answer:

The closest amount paid is $23

<em></em>

Step-by-step explanation:

Given

$Price = \$32$

$Mark\ down = 20\%$

Amount = 10% of Marked down price

Required

Determine the amount paid

First, we calculate the marked down price P2:

$P_2 = Price(1 - Mark\ down)$

Substitute values for Price and Mark down

$P_2 = \$32 * (1 - 20\%)$

Express percentage as decimal

$P_2 = \$32 * (1 - 0.20)$

$P_2 = \$32 * (0.80)$

Remove bracket

$P_2 = \$32 * 0.80$

$P_2 = \$25.6$

The payable amount is 10% off the marked down price,

This is calculated as:

$Amount = P_2 - P_2 * 10\%$

Substitute $25.6 for P2

$Amount = \$25.6 - \$25.6* 10\%$

Express percentage as decimal

$Amount = \$25.6 - \$25.6* 0.10$

$Amount = \$25.6 - \$2.56$

$Amount = \$23.04$

<em>The closest amount paid is $23</em>

2(5m-8)+3(m+2)=12+4(2m-1)

FrozenT [24]

Answer:

3.6

Step-by-step explanation:

2(5m-8)+3(m+2)=12+4(2m-1)

10m - 16 + 3m + 6 = 12 + 8m -4

13m - 10 = 8 + 8m

13m = 18 + 8m

5m = 18

m = 3.6

Factor completely: a^n+a^(n+1)<br> 100 Points!

zlopas [31]

Answer:

$a^n\left(1+a\right)$

Step-by-step explanation:

Considering the expression

$a^n+a^{\left(n+1\right)}$

Steps

$a^n+a^{n+1}$

$\mathrm{Apply\:exponent\:rule}:\quad \:a^{b+c}=a^ba^c$

$a^n+a^1a^n$

$\mathrm{Factor\:out\:common\:term\:}a^n$

$a^n\left(1+a\right)$

Therefore, factoring $a^n+a^{\left(n+1\right)}$ will bring $a^n\left(1+a\right)$ .
