Step-by-step explanation:
To distribute the water equally, you divide the 5 gallons of H2O by 6 people. You will get the fraction 5/6 as your answer.
Answer:
Step-by-step explanation:
<u>We need to add up 4 angles to get 360.</u>
<u>Here is what you fill out for the missing boxes:</u>
- 70 + 70 = 130
- 70 goes into the smallest angle.
- 115 + 115 = 230.
- If we do 120 or 130, It would make 370 or 390.
- 130 + 230 = 360.
- 50 + 50 = 100.
- Missing 50 goes into smallest angle.
- 130 + 130 = 260.
- 260 + 100 = 360.
Answer:
x = - 6 or x = 2
Step-by-step explanation:
The absolute value function always returns a positive value. However, the expression inside can be positive or negative.
Given
| 2x + 4 | - 1 = 7 ( add 1 to both sides )
| 2x + 4 | = 8, thus
2x + 4 = 8 ( subtract 4 from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
OR
-(2x + 4) = 8
- 2x - 4 = 8 ( add 4 to both sides )
- 2x = 12 ( divide both sides by - 2 )
x = - 6
As a check
Substitute these values into the left side of the equation and if equal to the right side then they are the solutions.
x = 2 → | 4 + 4 | - 1 = | 8 | - 1 = 8 - 1 = 7 ← True
x = - 6 → | - 12 + 4 | - 1 = | - 8 | - 1 = 8 - 1 = 7 ← True
Hence the solutions are x = - 6 or x = 2
