X2-64=0
x2=64
x=8 because when multiplied by itself, and plugged back in, it works
3.6 / 0.2 = 18 liter glasses :))
The slope of the equation would be 7/3 since the original slope was -3/7. We already know y int (b) so the eqn is
y = 7/3x + 2
If there are 3 more girls than boys then you can divide 29 by 2 and have 1 get 3 more so girls= 13 boys= 16 16+13=29
Answer: 9 envelopes
Step-by-step explanation:
Divide the 45 checks into 9 groups of 5.
------------------------------------------------------------------------
| 5 | 5 | 5 | 5 | 5 | 5 | 5 | 5 | 5 |
------------------------------------------------------------------------
45 checks divided into 9 envelopes equals 5 checks per envelope
45 ÷ 5 = 9
Take away one group of 5 checks from the 45 checks. Then take away another group of 5 checks, and another, and another. When there are no more checks, count how many groups you took away. You can take 9 groups away from 45, so that is your answer.
To tell that the answer is 9 groups of 5 checks, follow these steps.
Look at the equation. 45 ÷ 5 = 9.
The amount of groups is what 45 ÷ 5 equals. What the 45 checks is divided by is the amount in each group.
This means that there are 9 groups of 5 checks.
