Answer:
Step-by-step explanation:
1. Combine Like Terms
24 + 6a = 6 - 4a
+4a +4a
24 + 10a = 6
-24 -24
10a = -18
___ ___
10 10
a= -1.8
Answer:
Option B, random sample
That should be the answer
Answer
89x-7
Step-by-step explanation:
Set up a proportion like this
=
So your proportion would be:
We put x for offices because they are asking for the number o offices a crew can paint in 12 hours, and also we don't know the number of offices they can paint in 12 hours
so we cross multiply and we get
6x=60, we got 60 by multiplying 12 and 5
Now we divide both sides by 6 and we get
x=10
S the crew can paint 10 offices in 12 hours.
The number in question is equal to 2 times the temperature in degrees Celsius.
<h3><u>Equations</u></h3>
Since Alisha is working on a project about temperature conversion in her science class, and the formula for converting degrees Celsius to degrees Fahrenheit is F=C+32, to solve FC + 32 the following equation must be performed:
- CF + 32 = X
- F + F + 32 + 32 = X
- 2F + 64 = X
- F + 32 = 1/2X
- X = 2C
Therefore, the number in question is equal to 2 times the temperature in degrees Celsius.
