Answer:

17 units

Step-by-step explanation:

2{(2x + 3) + (3x + 2)} = 60

5x + 5= 60/2

5x + 5 = 30

5x = 30 - 5

5x = 25

x = 25/ 5

x = 5 units

PQ = 3x + 2 = 3*5+ 2 = 15 + 2 = 17 units

Lubov Fominskaja [6]

Answer:

0.5 liters of milk are available per child.

Step-by-step explanation:

Amount of milk available per children:

The amount of milk, in liters, available for x children is given by:

$m(x) = \frac{25}{x}$

50 children are present on a day

This means that $x = 50$

How much milk is available per child?

This is m(50). So

$m(50) = \frac{25}{50} = 0.5$

0.5 liters of milk are available per child.

Factor 21c+24.<br> Write your answer as a product with a whole number greater than 1.<br> use ()

Lera25 [3.4K]

Answer:

The required answer as a product with a whole number greater than 1 will be:

$21c+24=3\left(7c+8\right)$

Step-by-step explanation:

Given the expression

$21c+24$

Determining the factor

$21c+24$

Rewrite 24 as 3 · 8

Rewrite 21 as 3 · 7

so the expression becomes

$21c+24=3\cdot \:\:7c+3\cdot \:\:8$

Factor out the common term 3

$=3\left(7c+8\right)$

Therefore, the required answer as a product with a whole number greater than 1 will be:

$21c+24=3\left(7c+8\right)$
