Answer: 34 degrees
Step-by-step explanation:
The starting temperature was -5 degrees at 5am, and after two hours, the temperature was 34 degrees at 7am. The temperature increased by 39 degrees, how did we get this answer?
You add -5 and 39
-5 + 39 = 34
A tip for adding negatives:
When you get a problem similar to -5 + 39, you can actually flip them around if you need an easier understanding. So it would be 39 - 5. Both equations still equal 34 as long as you keep the values of each number!
Answer:
The answer is $206,451
Step-by-step explanation
This scenario is asking to subtract 19 percent away from 229,390 .
Step one : Divide 229,390 by 10 ( take away the zero behind the 9 )
Step 2 : Subtract 22,939 from 229,390 since we know ten percent of 229,390 is 22,939 = 206451
3a + 4bc - d = 5a - 8j
<em><u>Add d to both sides.</u></em>
3a + 4bc = 5a - 8j + d
<em><u>Subtract 4bc from each side.</u></em>
3a = 5a - 8j + d - 4bc
<em><u>Subtract 5a from both sides.</u></em>
-2a = -8j + d - 4bc
Divide both sides by -2
a =
