I got it right on the test

2/11 is lower than 2/9, therefore the equation that will represent a lower unit rate (k) of both relationships given is: D. y=2/11

A proportional relationship between variable y and x can be expressed as:

y = kx

k is the unit rate/constant of proportionality.

k = y/x

Thus, find the equation for the table and the graph respectively in order to determine which equation represents the lower unit rate.

Equation for the table using a pair of coordinates, say (11, 2):

Find, unit rate (k) by substituting x = 11, and y = 2 into k = y/x

k = 2/11

Plug in the value of k = 2/11 into y = kx

The equation for the table is:

y = 2/11x

Equation for the graph using a point on the line, say (9, 2):

Find, unit rate (k) by substituting x = 9, and y = 2 into k = y/x

k = 2/9

Plug in the value of k = 2/9 into y = kx

y = 2/9x

In conclusion, 2/11 is lower than 2/9, therefore the equation that will represent a lower unit rate (k) of both relationships given is: D. y=2/11

Answer:

A. x=35

B. C= 59 degrees

Step-by-step explanation:

Since both angles have the same measurement you set them equal to each other as so & solve for x

3x+16=5x-54

16=2x-54

70=2x

x=35

Now we plug 35 into one of the equations

3(35) + 16

105+ 16 = 121 degrees

Since angle C is a supplementary angles you do 180-121= 59 degrees

Answer:

5 months

Step-by-step explanation:

Make the question into an equation where the cost of one gym equal to the cost for the other.

60x = 100 + 40x

x represents how many months

20x = 100

x = 5

It would take 5 months of membership for the costs to be the same.

The answer is 5 months.

The linear equation is made using the constraints given in the question, examining whether the data is added, subtracted, divided, or multiplied.

To solve the linear equation we group the variable on the LHS and then equate it with the constant and this is done by transposing, or using an arithmetic operator on both sides.

Let the number of months taken be 'x'

SO the community fitness takes 60x money for x months

The fitness center where she works takes an amount of 100+40x for x months as registration fees are only charged once.

so equating the equation to find the value of x.

100+40x = 60x

Transposing 40x from LHS to RHS

100=60x-40x

20x = 100

Dividing the equation by 20 on both sides

x = 5

The membership costs will equal in 5 months.

Answer:

The general rule for estimating is to look at the digit to the right of the digit you want to estimate. Estimating or rounding to the nearest whole number means looking at the digit to the right of the decimal. If you see a digit greater than 5, round up, and if it's less than 5, round down.

Step-by-step explanation:

Let the missing number be x .

Then :-

[tex]4(11 + 7) = x + 28[/tex]

[tex]4 \times 18 = x + 28[/tex]

[tex]72 = x + 28[/tex]

[tex]x + 28 = 72[/tex]

[tex]x = 72 - 28[/tex]

[tex]x = 44[/tex]

Therefore , 4 ( 11 + 7 ) = 44 + 28 .

Answer:

5a.

Step-by-step explanation:

The HCF is short for Highest Common Factor.

Write the 2 expressions in factor form:

5a = 5 * a

15a = 5 * 3 + a

Note that 5 and a are common to both sets of factors, so the HCF = 5a.

Given:

A rectangular rug in her living room that is 6 feet wide and 8 feet long.

She orders a new one that covers twice as much area.

New rug is 1.5 times as wide as the original rug.

To find:

The length of new rug.

Solution:

We have,

Length of rug = 8 feet

Width of rug = 6 feet

Area of rug is

[tex]Area=length \times width[/tex]

[tex]A_1=8 \times 6[/tex]

[tex]A_1=48\text{ sq. feet}[/tex]

Area of new rug is twice of area of original rug.

[tex]A_2=2\times A_1[/tex]

[tex]A_2=2\times 48[/tex]

[tex]A_2=96\text{ sq. feet}[/tex]

New rug is 1.5 times as wide as the original rug.

Width of new rug = 1.5 × 6 = 9 feet

Let the length of new rug be x feets. So, area of new rug is

[tex]A_2=x\times 9[/tex]

[tex]96=x\times 9[/tex]

Divide both sides by 9.

[tex]\dfrac{96}{9}=x[/tex]

[tex]\dfrac{32}{3}=x[/tex]

[tex]x=\approx 10.67\text{ feet}[/tex]

Therefore, the length of new rug is about 10.67 feet.

Hi friend! The answer is D. 10

Answer:

B) 10

Step-by-step explanation:

Assign variables to each person:

A=Alina's Age

M=Amy's Age

G=Greg's Age

Set up a system of equations given the information:

A=6+G

M=2.5A

M=40

Notice that M is already given, so we can plug that into the second equation:

40=2.5A

16=A

So Alina is 16 years old, but the problem asks for Greg's age, so we plug Alina's age in the first equation:

16=6+G

10=G

So Greg is 10 years old, therefore B is the correct answer.

Answer:

41.94

Step-by-step explanation:

12 divided by 2 is 6 and six times 6.99 gets you your answer of 41.94

Answer:

$72.00

Step-by-step explanation:

Lets round $6.99 to $7.00. Now we have an easier number to work with.

To find the total price of 12 , we need to multiply $7.00 by 12.

⇒ $7.00 x 12 = $84.00

Since we added 1 cent to $6.99 and multiplied by 12, we need to sutract 1 times 12.

1 x 12 = 12

$84 - $12 = $72.00
