Answer:
12.5 minutes
Step-by-step explanation:
it takes 5 minutes to cool 10 degrees
after ten minutes it would be 20 degrees less
then after 2.5 minutes it would be 5 degrees less
so it would take you 12.5 minutes to get 25 degrees less
Answer:
so 20*5=100 and a percent is out of 100
so we just multiply 18*5 which equals
90 so 18/20=90%
we could also figure this out because if we simplify we get
9/10 which is also 90%

Answer:B
Step-by-step explanation:if it's a negative 3/4x then in be there is a -4 and there is a -7 so we can do -7 -4 but 4 is a negative so it turns into a positive so it's _
-7+4 and it become a smaller negative so -7+4 = -3. So it has to be B. Hope this gets brainliest
Answer: 17 and 25
Step-by-step explanation:
Let X and Y be the two numbers.
---------------
X + Y = 42 [sum of two numbers is 42]
X - Y = 8 [their difference is 8]
-------------------
Rearrange the last equation to
X = 8 + Y
Now enter that into the 1st equation:
X + Y = 42
(8+Y) + Y = 42
2Y = 34
<u>Y = 17</u>
Since X - Y = 8,
X = 8 + 17
<u>X = 25</u>
===
X + Y = ?
17 + 25 = 42 <em>Checks</em>
X - Y = ?
25 - 17 = 8 <em>Checks</em>
