Two teachers purchase supplies for their classrooms.

inna [77]

Answer:

Cost of One Journal = $3.99

Cost of One pen = $0.59

Step-by-step explanation:

Let

Cost of One Journal = x

Cost of One pen = y

We can make equation from given statements.

Mr. Bowden purchases 18 journals and 40 pencils for $95.42.

$18x+40y=95.42$

Ms. Jacinto purchases 11 journals and 16 pencils for $53.33.

$11x+16y=53.33$

Now solving these equations to find the value of x

$18x+40y=95.42--eq(1)\\11x+16y=53.33--eq(2)$

Multiply eq(1) with 2 and eq(2) with 5

$36x+80y=190.84\\55x+80y=266.65\\-\:\:\:\:-\:\:\:\;\:\:\:\:\:\:\:-\\---------\\-19x=-75.81\\x=\frac{-75.81}{-19}\\x=3.99\\$

We get the value of x is: x=3.99

Now, putting value of x in equation 1 to find value of y.

$18x+40y=95.42\\18(3.99)+40y=95.42\\71.82+40y=95.42\\40y=95.42-71.82\\40y=23.6\\y=\frac{23.6}{40}\\y= 0.59$

So, we get the value of y: y = 0.59

Now, finding the costs:

Cost of One Journal = x = $3.99

Cost of One pen = y = $0.59

11.15+11.75+10.70 I need some help with this problem

Nina [5.8K]

Answer:

33.60 is your answer

Step-by-step explanation:

Remember to add based on place value.

Note that 10.70 is the same as 10.7

11.15 + 11.75 = 22.90

22.90 + 10.7 = 33.60

we know that

A gallon of white paint must mixed with 2 gallons of brown paint

using proportion

$\frac{1}{2}\frac{gallon\ white}{gallons\ brown} =\frac{x}{8}\frac{gallons\ white}{gallons\ brown}\\\\x=8/2\\x=4\ gallons\ white$

Sage has 3 strip-mats, 3 mats, and 2 units. Tristan has 2 mats, 8 strips, and 5 units. Andre had twice as many strip-mats, mats,

sladkih [1.3K]

The question is an illustration of equivalent equations.

<em>There are 11 units in all</em>

The given parameters are:

<u>Sage</u>

$\mathbf{Strip-mat = 3}$

$\mathbf{Mat = 3}$

$\mathbf{Units = 2}$

<u>Tristan</u>

$\mathbf{Strip-mat = 8}$

$\mathbf{Mat = 2}$

$\mathbf{Units = 5}$

Andre has twice of what Sage has

So, the total unit is:

$\mathbf{Total = Sage + Tristan + Andre}$

<em>Sage has 2 units</em>

<em>Tristan has 5 units</em>

<em />

Because, Andre has twice of what <em>Sage has,</em>

Andre's number of units would be 4

So, we have:

$\mathbf{Total = 2 +5 + 4}$

$\mathbf{Total = 11}$

Hence, there are 11 units in all
