Who made more choices commission this month? How much did she make? Salesperson A made 11% of $67,530. Salesperson B made 8% of $85,740.

Answers

Answer Step-by-step explanation:

$Salesperson~A=$ $11$ % $of~67,530=(11)/(100) *67530=0.11$

$=0.11*67530=7,428.3$

$Salesperson~B=$ $8$ % $of~85,740=(8)/(100)*85740= 0.08$

$=0.08*85740=6,859.2$

$7,428.3$ > $6,859.2$

$Thus,~Salesperson~A~made~more~commission~than~Salesperson~B.$

Which number is between 0.6 and 7/9

A 23/27
B 31/45
C 14/27
D 1/3

Answers

The best way to find the answer is to convert the fractions to decimals using a calculator.
(7/9) is (0.7777). This means that we are looking for a number between 0.6 and 0.7777.
A. (23/27) is .8519. This is not the answer.
B. (31/45) is .6889. This falls in between 0.6 and 0.777 because 0.6 is less than 0.6889 and 0.7777 is greater than 0.6889.

There is no reason to look at C and D because we know that B is the answer.

-1(x+2)=2(3x-6)
Please solve

Answers

$-1(x+2)=2(3x-6)$
$-1(x+2)=2(3x-6)$ distributhing -1 through parantheses
$-1x+(-1)*2=2(3x-6)$
$-x-2=2(3x-6)$ distributhing 2 through parantheses
$-x-2=2*3x-2*6$
$-x-2=6x-2*6$
$-x-2=6x-12$ add x
$-2=6x-12+x$
$-2=7x-12$ add 12
$-2+12=7x$
$10=7x$ divide by 7
$x= (10)/(7)$
Answer : x= 1 3/7

-1(x + 2) = 2(3x - 6)

First, simplify 1 × (x + 2) to (x + 2) / Your problem should look like: $-x - 2 = 2(3x - 6)$
Second, expand. / Your problem should look like: $-x - 2 = 6x - 12$
Third, add x to both sides. / Your problem should look like: $-2 = 6x - 12 + x$
Fourth, simplify 6x - 12 + x to get 7x - 12. / Your problem should look like: $-2 = 7x - 12$
Fifth, add 12 to both sides. / Your problem should look like: $-2 + 12 = 7x$
Sixth, add -2 + 12 to get 10. / Your problem should look like: $10 = 7x$
Seventh, divide both sides by 7. / Your problem should look like: $(10)/(7) = x$
Eighth, switch your sides. / Your problem should look like: $x = (10)/(7)$

Answer: x = $(10)/(7)$
