Solve: -1/4 (2x + 8) = -6

vredina [299]

Answer:

x = 8

Step-by-step explanation:

-1/4 (2x + 8) = -6

Multiply both sides by -4.

2x + 8 = 24

Subtract 8 from both sides.

2x = 16

Divide both sides by 2.

Principal clements wants to buy a pencil for each of the 57 fourth graders in her school. The pencils come in packages of 6. How

Scrat [10]

Principal clements needs to buy 10 packages

Solution:

Given that, Principal clements wants to buy a pencil for each of the 57 fourth graders in her school

The pencils come in packages of 6

Therefore,

Total number of students = 57

Thus, divide 57 by 6 to get the number of packages clements need to buy

$\text{Number of packages } = \frac{\text{total number of students }}{6}$

Substituting the given values we get,

$\text{Number of packages } = \frac{57}{6} \\\\\text{Number of packages }= 9.5 \approx 10$

Thus principal clements needs to buy 10 packages
