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

PLEASE HELP ASAP. SOLVE FOR X AND Y. SHOW ALL WORK.

The solution to the system of equations is (-3.88, 0.66) and (3.04, 1.09)

<h3>How to determine the solution to the system of equations?</h3>

The system of equations is given as:

x^2y + yx^2 = 20

1/x + 1/y = 5/4

Multiply through the equation 1/x + 1/y = 5/4 by 4xy

So, we have:

4x + 4y = 5xy

So, we have the following system of equations

4x + 4y = 5xy

x^2y + yx^2 = 20

Next, we plot the graph of the system of equations

4x + 4y = 5xy

x^2y + yx^2 = 20

See attachment for the graph of the system

From the attached system, we have the point of intersection to be

(x, y) = (-3.88, 0.66) and (3.04, 1.09)

Hence, the solution to the system of equations is (-3.88, 0.66) and (3.04, 1.09)

Jared is redoing his bathroom floor with tiles measuring 6 in. by 14 in. The floor has an area of 8,900 in. What is the least nu
Bond [772]
Firstly we need to find an area of a single tile:

6 * 14 = 84 square inches

Now we just need to find out how many tiles of 84 square inches will fit in an area of 8900 square inches:

8900 ÷ 84 = 105,952380952381

Assuming we can't cut a tile into pieces, we may round the result to 106.

Answer: The least number of tiles Jared will need is <u>106</u>.
