Answer:
27 Units
I just took the test and got 100 percent
It isn’t, because the numbers on the x are going up by 4 while the numbers on the y (x,y) are going up by 3, so it isn’t a 2:1 ratio
Answer:
20%
Step-by-step explanation:
Use the formula:
The "|" symbol represents absolute value and the dashed line represents a division line.
| Theoretical Value - Actual Value |
Percent Error = -------------------------------------------------- × 100
| Theoretical value |
- 100 students is the theoretical value
- 120 students is the actual value
100 - 120 = -20
-20 / 100 = -0.2
|-0.2| = 0.2
0.2 × 100 = 20
The answer is 20%
Answer:
<em>15</em>
<em> + 7x + 12</em>
Step-by-step explanation:
(6x^2 + 7x + 2) - (-9x^2 - 10)
Flip the sign:
- (-9x^2 - 10) becomes + 9x^2 + 10
Combine like terms:
6x^2 + 7x + 2 + 9x^2 + 10
6x^2 + 9x^2 = 15x^2
2 + 10 = 12
Put it all together:
15x^2 + 7x + 12
