Answer: $0.95 each

Step-by-step explanation:

The price of the oranges needs to be subtracted from the total cost before tax of $22.02.

The result will then be divided by 20 to find out the cost per juice box.

Equation is:

jj = (22.02 - 3.02) / 20

Solving it:

= (22.02 - 3.02) / 20

= 19 / 20

= $0.95 each

Write as a mixed number in lowest terms 7.25
Verizon [17]
7.25 is the same as 7 \frac{25}{100} written as a mixed number. However, .25 is \frac{1}{4} of 100.

In this case, while rewriting your mixed number, 7.25 is the same as 7\frac{1}{4}, so that would be your answer.

7.25 ⇒ 7 1/4

Answer:

Multiply the first equation by 3 and multiply the second equation by -2.

This is justified by the multiplication property of equality

Step-by-step explanation:

we have

2x+5y=7 ----> first equation

3x+4y=6 ----> second equation

step 1

Multiple the first equation by 3 both sides

3(2x+5y)=3(7) -----> by multiplication property of equality

6x+15y=21 ----> new first equation

step 2

Multiple the second equation by -2 both sides

-2(3x+4y)=-2(6)  -----> by multiplication property of equality

-6x-8y=-12 ----> new second equation

step 3

Solve the system of equations by elimination

Adds new first equation and new second equation

6x+15y=21\\-6x-8y=-12\\-------\\15y-8y=21-12\\7y=9\\y=\frac{9}{7}

Find the value of x

substitute the value of y in any equation and solve for x

6x+15y=21

6x+15(\frac{9}{7})=21

6x=21-\frac{135}{7}

6x=\frac{12}{7}

x=\frac{2}{7}

The solution is the point (\frac{2}{7},\frac{9}{7})

therefore

Multiply the first equation by 3 and multiply the second equation by -2.

This is justified by the multiplication property of equality

Spencer bought 3 books of stamps and mailed a package. it cost $4.50 to mail the package. define a variable and write an express
vladimir2022 [97]
X = The cost of each book of stamps

There for your expression would be:
3x + 4.50

3x is 3 book of stamps times x cost of each book.
Your 4.50 is your one time fee to mail the package.

Hope this helps! (:
