Evren used 24 centimeters of tape to wrap 3 presents. How many presents would Evren be able to wrap with 112 cm of tape?

Paul [167]

Answer:

Step-by-step explanation:

Since we're given the conversion 24 cm for every 3 presents wrapped, we can divide our total amount of tape by this conversion, assuming a constant proportion.

Evren has 112 cm of tape. We can write the following proportion:

$\frac{112}{x}=\frac{24}{3}$ , where $x$ is the number of presents he can wrap with 112 cm.

Cross-multiplying, we have:

$24x=336,\\x=\frac{336}{24}=\boxed{14\text{ presents}}$

The boundary lines for the system of inequalities is given in the graph.

diamong [38]

Answer:

region C

Step-by-step explanation:

We have to use what is called the zero-interval test [test point] in order to figure out which portion of the graph these inequalities share:

$\displaystyle y ≤ -x + 2$

0 ≤ 2 ☑ [We shade the portion of the graph that CONTAIN THE ORIGIN, which is the bottom portion.]

$\displaystyle y ≥ 2x - 3$

0 ≥ −3 ☑ [We shade the portion of the graph that CONTAINS THE ORIGIN, which is the left side.]

So, now that we got that all cleared up, we can tell that both graphs share a region where the ORIGIN IS VISIBLE. Therefore region C matches the above inequalities.

I am joyous to assist you anytime.

There are a few boxes with 12 red pens in each and a few boxes with 10 blue pens in each. If 10 red pens and 5 blue pens are rem

jolli1 [7]

Answer with explanation:

x=the number of boxes containing red pens and

y = the number of boxes containing blue pens.

The expression which describes the number of red pen and blue pen in Boxes is

= (12 x-10)+(10 y-5)

The equivalent expression are

1.By Adding like terms

=12 x +1 0 y -10 -5

=12 x +1 0 y -15

or Using Associative Property of addition of three numbers which is

⇒a+(b+c)=(a+b)+c=(a+c)+b

= 10 y +12 x -15

= -15 +10 y +12 x

= 12 x -15 +10 y
