Answer:
1 hour 13 min
Step-by-step explanation:
Given data
Start time= 6:35 PM
Finish time= 7:22 PM
Hence the time spent is
=7:22-6:35
=1:13
Hence the time spent is 1 hour 13 min
Answer:
The answer is b.) -5.2 degrees
Step-by-step explanation:
to find the mean of this problem you have to add all numbers and then divide it by how many numbers there is.
so you have to add -42+ -17+14+-4+23 and that'll equal -26
so you take -26 and divide it by 5 because thats how many numbers their are to divide
-26 divided by 5 is (-5.2)
The expression you have is already in its simplest form. However, there is another way to write it.
m - n/4
This expression is the same as the original, apart from the fact that we wrote the division as a fraction.
5x - 14y = 22 ⇒ 5x - 14y = 22
-6x + 7y = 3 ⇒ <u>12x - 14y = -6</u>
<u>-7x</u> = <u>28</u>
-7 -7
x = -4
5x - 14y = 22
5(-4) - 14y = 22
-20 - 14y = 22
<u>+ 20 + 20</u>
<u>-14y</u> = <u>42</u>
-14 -14
y = -3
(x, y) = (-4, -3)
Answer:
My own answer to your question is x=10
