It cost Naomi $7.70 to send 154 text messages. How many text messages did she send

s2008m [1.1K]

You have to find the unit rate

SO..

7.70 / 154 = 0.05

So it cost her 0.05 cents for each text.

So then you divide $ 5.25 by the unit rate to get the number of text

5.25 /0.05 = 105

so she sent 105 text

To check it you just multiply the unit rate by the number of text you got and you show come up with $ 5.25

0.05 x 105 = 5.25

What is the value of x in simplest radical form?

Ostrovityanka [42]

In this case, we will use our Pythagorean Theorem.

a = 84
b = 13
c = x

$\sqrt{84^2 + 13^2} = 85$

Thus, x = 85.

Mrs. Huynh bought a bag of 3 dozen toy animals as party favors for her son’s birthday party. The bag of toy animals cost $28.97.

Luda [366]

Answer: $price\ of\ each\ toy\approx\$1$

Step-by-step explanation:

Knowing that Mrs. Huynh bought a bag of 3 dozen toy animals. The total number of animals in the bag is:

$3*12=36$

The cost of the bag was $28.97, so you must divide 36 by $28.97 in order to know the price of each toy animal.

To estimate this quotient, the first round the numbers so that they are easier to work with.

We can say that:

$28.97\approx30\\\\36\approx30$

Then:

$30\div30\approx1$

Therefore, you can estimate that the price of each toy animal is:

$price\ of\ each\ toy\approx\$1$
