Substitute first Y for the second Y
So it would be x + x + 6 = -2
Then it would be 2x +6 = -2
Move the 6 over so it would be 2x =-8
Divide by 2 your answer is x = -4
1. true.
2. false.
3. false.
4. true.
these should be correct.
To convert radians to degrees, make use of the fact that pi<span> radians equals one half circle, or 180º.</span>
<span>This means that if you divide radians by </span>pi, the answer is the number of half circles. Multiplying this by 180º will tell you the answer in degrees.
<span>So, to convert radians to degrees, multiply by <span>180/</span></span>pi, like this:
Degrees= radians X 180/pi

Answer:
20/7 days (just less than 3 days)
Step-by-step explanation:
Recall that (1 job) = (rate)(time), so time = (1 job) / (rate).
Set up and solve the following equation:
1 job
------------------------------- = time required for 2 pumps working together
1 job 1 job
---------- + -------------
4 days 10 days
This comes out to:
1 job
------------------------------------------- = time required
10 job-days 4 job-days
------------------ + -----------------
40 days 40 days
or:
1 job
-------------------- = (40/14) days, or 20/7 days (just less than 3 days)
14 job·days
-----------------
40 days
