Answer:

B.) 1\frac{7}{12}

Step-by-step explanation:

2\frac{1}{4} -\frac{2}{3} Then multiply 4 by 2, then add 1.frac{9}{4} - \frac{2}{3} \\

Then find the Least Common Denominator(LCD); simply just multiply 4 by 3 to get 12; then multiply using the opposite number.

\frac{3}{3} *\frac{9}{4} - \frac{4}{4} * \frac{2}{3}

to get: \frac{27}{12} - \frac{8}{12}.

now the denominators is the same on both sides, just subtract the numerator.

27 - 8 = 19

Now simply: \frac{19}{12} = 1\frac{7}{12}.

Your final answer is 1\frac{7}{12}[/tex].

Y_Kistochka [10]

Answer:

A. $27.23

B. $467.77

Step-by-step explanation:

Lin is shopping for a couch with her dad and heard him ask the salesperson “how much is your commission?” The salesperson says that her commission is 5 1/2% of the selling price. A.How much commission will the salesperson earn by selling a couch for $495?

B.How much money will the store get from the sale of the couch?

Salesperson commission = 5 1/2%

Price of couch = $495

A. Amount earned by the salesperson = 5 1/2% of $495

= 5.5% × 495

= 0.055 × 495

= 27.225

Approximately

Amount earned by the salesperson = $27.23

B.How much money will the store get from the sale of the couch?

Amount the store get = Total price - amount earned by salesperson

= $495 - $27.23

= $467.77

Ted practices two types of swimming styles for a total of 50 minutes every day. he spends 20 minutes more practicing the breast
cluponka [151]

Answer:

see below

Step-by-step explanation:

butterfly = x minutes

breast = y minutes

total is 50 minutes

breast stroke = butterfly +20

Part A

x+y = 50

y = x+20

Part B

Substitute the second equation into the first

x+ (x+20) = 50

2x+20 = 50

2x+20-20 = 50-20

2x = 30

2x/2 = 30/2

x = 15

y = x+20

y = 20+15

y = 35 minutes

35 minutes on the breast stroke

Part C

45 minutes on the butterfly is not reasonable

We only have a total of 50 minutes

50-45 = 5

But he spend more time on the breast stroke ( 20 minutes more), but if he spend 45 minutes on the butterfly, he would have to spend less on the breast stroke.
