Complete the missing value in the solution to the equation.

Answer:

x + y = 5

12x + 8y = 48

x = -y + 5

12(-y + 5) + 8y = 48

-12y + 60 + 8y = 48

-4y + 60 = 48

-4y = -12

y = 3

x + 3 = 5

x = 2

12(2) + 8(3) = 48

24 + 24 = 48

x = 2 hours of washing cars

y = 3 hours of landscaping

Hope this helps!!

The value of x and y should be 2 and 3.

Since Gianna is working two summer jobs, making $12 per hour washing cars and $8 per hour landscaping. Last week Gianna worked a total of 5 hours and earned a total of $48.

So here the equation should be

x + y = 5

12x + 8y = 48

we can write as

x = -y + 5

So,

12(-y + 5) + 8y = 48

-12y + 60 + 8y = 48

-4y + 60 = 48

-4y = -12

y = 3

Now

x + 3 = 5

x = 2

Therefore, The value of x and y should be 2 and 3.

Answer:

The unit rate for miles per gallon is 33.75. 33.75 as a fraction 135/75

Step-by-step explanation:

35.5 divided by 1.75 is 33.75

33.75 as a fraction is 135.75 which is an improper fraction

So you have to divide the numerator by the denominator

135 divided by 75 is 1.8 as a decimal

Answer:

28.4

Step-by-step explanation:

35 1/2 miles over 1 1/4 gallons of gasoline. 1 1/4 converted into an improper fraction is 5/4, so you multiply the numerator and denominator by 5/4. You need to multiply by 5/4 because you need to get to miles per gallon, which equals to 1. (A fraction multiplied by its reciprocal will always equal 1) once you've multiplied the numerator and denominator by the reciprocal, your answer will be 28.4 - hope this helped!

Step-by-step explanation:

-28x + 10y = -120

 40x + 10y = 180

12x = 60

x = 5: D is the answer

8(5) - 2y = 36

y = 2: A is the other answer

Slope is the change in y over the change in x:

Slope = (-7 - 1) / (2 - 5)

Slope = -8/-3

Slope = 8/3

Answer:

1.11w

Step-by-step explanation:

Let initial wage = w

Percentage increase in wage = 11%

Using the relation :

New Amount = initial * (1 + % increase)

New Amount = w * (1 + 0.11)

New amount = w * (1.11)

New amount = 1.11w

Answer:

The equation of the line in the slope-point form is y - 7 = 10(x + 6)

The equation of the line in the slope-intercept form is y = 10x + 67

Step-by-step explanation:

The slope-point form of the linear equation is y - y1 = m(x - x1), where

The slope-intercept form of the linear equation is y = m x + b, where

∵ The slope of the line is 10

∴ m = 10

∵ The line passes through the point (-6, 7)

∴ x1 = -6 and y = 7

→ Substitute them in the slope-point form above

∵ y - 7 = 10(x - -6)

∵ (-)(-) = (+)

∴ y - 7 = 10(x + 6)

∴ The equation of the line in the slope-point form is y - 7 = 10(x + 6)

→ Substitute m in the slope-intercept form

∵ y = 10x + b

→ To find b substitute x by -6 and y by 7 in the equation

∵ 7 = 10(-6) + b

∴ 7 = -60 + b

→ Add 60 to both sides to find b

∴ 67 = b

→ Substitute the value of b in the equation

∴ y = 10x + 67

∴ The equation of the line in the slope-intercept form is y = 10x + 67

Answer:

Students altogether liked cola the best 26

Step-by-step explanation:

Total no of pupils = 60

Boys = 32

girls = 28

we will make a table

Gender         cola             milk               water       total

Boys             12                                         4              32

Girls                                                          9                28

we can find the missing numbers

Let x be for milk

In boys  12 + x + 4 = 32

                 x  = 16

In girls

          as 21 liked milk altogether

so girls = 21 - 16 = 5

Gender         cola             milk               water       total

Boys             12                 16                      4              32

Girls                                   5                      9                28

For cola let y

in girls

y + 5 + 9 = 28

y = 14

Gender         cola             milk               water       total

Boys             12                 16                      4              32

Girls              14                   5                      9            28

Altogether cola = 14 + 12 = 26

Answer:

Fixed expences are expences that don't change month-to-month, whereas variable expences are things that are needing to budgeted for every month, but may vary a bit and are therefor usually estimated on a budget.

Step-by-step explanation:

For example, rent would be a fixed expense because you know it will be X amount due on the same day every month.  Food, on the other hand, would be a variable expense because it likely won't be the same amount month-to-month.

Answer:

Fixed expenses are expenses that stay the same for a person or a business. An example of a fixed expense is rent/mortgage. This expense doesn't change if you are only using the building for 2 weeks or the entire month, it's a set rate. A variable expense is an expense that changes like an electric bill, it varies based on the month and usage. When you budget, you can easily budget for your fixed expenses but you need to allow some room in your budget for expenses that change.

Answer:

7.04% decrease

Step-by-step explanation:

Lets use 5 example

5*0.17=0.85

5-0.85=4.15

4.15*0.12=0.498

4.15+0.498=4.648

7.04% of 5 is 4.648

Answer:

See Below.

Step-by-step explanation:

Let:

[tex]0.\overline{5}=n[/tex]

If we multiply both sides by 10, we get:

[tex]5.\overline{5}=10n[/tex]

Now, we will subtract n from both sides:

[tex]5.\overline{5}-n=10n-n[/tex]

On the left, we can replace the n:

[tex]5.\overline{5}-.\overline{5}=10n-n[/tex]

Subtract:

[tex]5=9n[/tex]

Divide both sides by 9:

[tex]n=\frac{5}{9}[/tex]

Hence:

[tex]n=0.\overline{5}=\frac{5}{9}[/tex]

Answer:

Step-by-step explanation:

Let [tex]n[/tex] and [tex]A[/tex] the number of jugs and the area of flowers, measured in jugs and square feet. We assume that exists a direct relationship between both variables. That is:

[tex]A \propto n[/tex]

[tex]A = k\cdot n[/tex] (1)

Where [tex]k[/tex] is the proportionality constant, measured in square feet per jug.

If we know that [tex]n = 1\,jug[/tex] and [tex]A = 140\,ft^{2}[/tex], then the proportionality constant is:

[tex]k = \frac{A}{n}[/tex]

[tex]k = 140\,\frac{ft^{2}}{jug}[/tex]

Then, the relationship between both variables is represented by:

[tex]A = 140\cdot n[/tex]

If we know that [tex]A = 175\,ft^{2}[/tex], then the minimum number of jugs needed to treat the area is:

[tex]n = \frac{175\,ft^{2}}{140\,\frac{ft^{2}}{jug} }[/tex]

[tex]n = 1.25\,jugs[/tex]

Since jugs represents a discrete set, then we round this number up to the next integer. In other words, we find that 2 jugs are needed to treat an area of 175 square feet.

Lastly, we present a graph to estimate the minimum value of jugs:
