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.
Yes.
Why?
They worked hard to get that answer by typing things and typing requires work.

Answer:
In mathematics, an nth root of a number x is a number r which, when raised to the power n, yields x.Where n is a positive integer, sometimes called the degree of the root.
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.
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.
