Alice has $560 in the bank. She uses 1/4 of it to buy a coat and 2/3 of the remaining money to buy a present for her mother. How
Alex

Answer: $140

Step-by-step explanation:

1/4 × 560 to buy a coat

= 0 25 x 560 = $140

Remaining balance after purchase of coat will be $560 - $140 = $420

Next, he uses 2/3 of $420 for present

2/3 × 420

0.667 x 420

= $280 for present

Alice's balance will be remaining balance after purchase of coat - money for present

= $420 - $280

=$140

I hope this is clear, please mark as brainliest answer. Thank you.

Choose the correct way to end the sentence.

Answer:  B) neither

================================================

Let's isolate y in the first equation. This way we can find the slope.

x-2y = 4

-2y = 4-x

-2y = -x+4

y = (-x+4)/(-2)

y = -x/(-2) + 4/(-2)

y = (1/2)x - 2

This matches with y = mx+b form with m = 1/2 being the slope.

The slope of y = 2x-2 is m = 2

------------------------------

The slope of the first line is 1/2 and the slope of the second line is 2.

Since the two slopes (1/2 and 2) are not equal, this means the lines are not parallel.

Also, the two slopes do not multiply to -1, so the lines aren't perpendicular either.

This leads to B) neither as the final answer.

Jacob spends 60 minutes in the gym every day doing freehand exercises and running on the treadmill. He runs on the treadmill 30
elixir [45]

Answer:

a.

x + y = 60

x = y + 30

b.

substitution:

(y + 30) = y = 60

2y + 30 = 60

2y = 30

y = 15

15 minutes for freehand

c.

No, because if he spends 40 minutes on the treadmill, he would have spent 10 minutes for freehand exercises. His total time in the gym would be 50 minutes, not 60.
