A pizza party will have 30 kids. A pizza has 12 slices, and each kid will eat 4 slices. How many pizzas will be needed?16 pizza
10 pizza
12 pizza
8 pizza

Answers

Answer:

10 pizzas

Solution:

We know that:

1 pizza = 12 slices
Pizza party = 30 kids
1 kid = 4 slices

This means that 3 kids will finish a pizza.

=> 3 kids = 1 pizza
=> 30 kids = 1 x 10 pizza
=> 30 kids = 10 pizzas

Hence, 10 pizzas will be needed.

Which number line represents the solutions to |x + 4| = 2?

Answers

Answer:

The solution is represented by the first number line, wich has the solutions x=-6 and x=-2.

Step-by-step explanation:

We have an absolute value function for the equation. This means that we should have two differents solution in the real number line. As the equation is

$|x+4|=2$

when we clear out the absolute value, we will have two possible solutions:

$x+4=2$

and

$-(x+4)=2$

now we clear x from both equations

$x+4=2 \Leftrightarrow x=2-4 \Leftrightarrow x=-2$

$-(x+4)=2 \Leftrightarrow -x-4=2 \Leftrightarrow -2-4=x \Leftrightarrow x=-6$

Then, we have that x=-2 and x=-4 are the solutions for the equation, and therefore the number line that represents the solution is the first one, where the points -6 and -2 are highlighted.

the first number line

given | x + 4 | = 2

removing the bars from the absolute value gives

x + 4 = 2 or x + 4 = - 2

x = 2 - 4 or x = - 2 - 4

x = - 2 and x = - 6 ← solutions

these are indicated on the number line by a solid circle at - 2, - 6
