Answer:

48 miles

Step-by-step explanation:

On Monday, Elliot rode 6 miles on a bike. On Tuesday, he rode 6 miles. On Wednesday, he rode 3 times farther than he did Monday and Tuesday combined.

How many miles has Elliot ridden so far this week?

This is calculated as:

Number of miles he rode on Monday + Number of miles he rode on Tuesday + Number of miles he rode on Wednesday

= 6 miles + 6 miles + 3(6 + 6)miles

= 12 miles + 3(12 miles)

= 12 miles + 36 miles

= 48 miles

Therefore, Elliot has ridden 48 miles so far

[tex]-2.6x-(-5.9x)[/tex] is equivalent to [tex]-2.6x+5.9x[/tex] and [tex]5.9x+(-2.6x)[/tex]

[tex]-2.6x+(-5.9x)[/tex] is equivalent to [tex]-2.6x-5.9x[/tex] and [tex]-5.9x+(-2.6x)[/tex].

The expressions which are equivalent to neither:

[tex]-5.9x+2.6x[/tex] and [tex]5.9x-(-2.6x)[/tex]

Step-by-step explanation:

Given the expressions:

1) [tex]-2.6x-(-5.9x)[/tex]

2) [tex]-2.6x+(-5.9x)[/tex]

To find:

The expressions equivalent to the given expressions.

or the expressions which are not equivalent to any of the given expressions.

Solution:

First of all, let us solve the brackets from the given expressions.

[tex]-2.6x-(-5.9x)[/tex] can be written as [tex]-2.6x+5.9x[/tex] (because when we multiply a negative sign with negative, it becomes positive.)

Similarly [tex]-2.6x+(-5.9x)[/tex] can be written as [tex]-2.6x-5.9x[/tex] (because when we multiply a positive sign with negative, it becomes negative.)

Therefore, the answer is:

[tex]-2.6x-(-5.9x)[/tex] is equivalent to [tex]-2.6x+5.9x[/tex] and [tex]5.9x+(-2.6x)[/tex]

[tex]-2.6x+(-5.9x)[/tex] is equivalent to [tex]-2.6x-5.9x[/tex] and [tex]-5.9x+(-2.6x)[/tex].

The expressions which are equivalent to neither:

[tex]-5.9x+2.6x[/tex] and [tex]5.9x-(-2.6x)[/tex]

What are the values of the veriables?

Answer:

4.) Choice B

    &

5.) Choice A

Step-by-step explanation:

Question 4:

First you have to solve for y to get slope intercept form.

[tex]2x-5y=6\\5y=-2x+6\\y=-\frac{2}{5}x+\frac{6}{5}[/tex]

The slope is a fraction but you need it to convert it to a decimal so that'll be Choice B.

Question 5:

For this one I we will use this formula [tex]m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

I will choose the easy pairs to plug it in [tex](-12,-2) (20,6)[/tex]

[tex]\frac{6--2}{20--12}\\\\\\\frac{8}{32}=\frac{1}{4}[/tex]

The slope is a fraction again but you can convert it and that'll be Choice A.

Answer:

Step-by-step explanation:

Answer: It would cost $17.5 travel 25 miles.

Step-by-step explanation:

Given: Flat rate = $15

Charge per mile = $0.10

Total cost = Flat rate + (Charge per mile) (Number of miles)

Let x= Number of miles traveled.

So Total cost = 15 +0.10x

Put x= 25 miles

Total cost = 15 +0.10(25)

= 15+2.5 = $17.5

Hence, it would cost $17.5 travel 25 miles.

The slope of the function is 10. The y-intercept is (0,5).

The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.

The slope of the line is calculated as follows:

m = Δy/Δx

Given that  the function y= 10x - 5.

To find the slope  and y-intercept of the function y= 10x - 5.

Therefore, the slope of the line is;

m = 10

The y-intercept of the function is (0,5)

Hence,C. The slope is 10.

The y-intercept is (0,5).

Answer:

x = 29

y = 10

Step-by-step explanation:

x - 3y = -1

Add 3y to both sides;

x = 3y - 1

2x - 5y = 8

Substitute x

2x - 5y = 8

2(3y - 1) - 5y = 8

Distribute;

6y - 2 - 5y = 8

Collect like terms;

y - 2 = 8

Add 2 to both sides;

y = 10

Substitute y

x - 3y = -1

x - 3(10) = -1

x - 30 = -1

Add 30 to both sides;

x = 29

Answer:

5. 27 + 21 = 48

6. 21 - 3 = 18

7. 12 + 9 = 21

Step-by-step explanation:

I could only see these three but I hope this helps :)

Answer:

4) x = 11

5) x = -6

6) x = 18

7) x = 21

Step-by-step explanation:

(the equations and the answers are bolded)

x + 9 = 21

subtract 9 from both sides of the equation

x + 9 - 9 = 21 - 9

x = 21 - 9

x = 11

21 - x = 27

add x to both sides

21 - x + x = 27 + x

21 = 27 + x

subtract 27 from both sides

21 - 27 = 27 - 27 + x

-6 = x

21 = x + 3

subtract 3 from both sides

21 - 3 = x + 3 - 3

21 - 3 = x

21 - 3 = 18

18 = x

x - 9 = 12

add 9 to both sides

x -  9 + 9 = 12 + 9

x = 12 + 9

x = 21

Answer:

x = -1

Step-by-step explanation:

add 9.5 to both sides to get x by itself and to keep both sides equal.

x = -1

Answer:

12 lunches.

Step-by-step explanation:

Theresa:

$8.50 * 11 = $93.50 so she can buy 11 lunches with her gift card.

Colin:

$6 * 12 = $72 so he can buy 12 lunches with his gift card.

So Colin can buy one more lunch than Theresa. Therefore, if Theresa buys 12 lunches, she will go over her gift card.

Answer:

The answer is C

Step-by-step explanation:

y = 4x + 12

y = 4(3) + 12

y = 12 + 12

y=24

y = 4x + 12

y = 4(5) + 12

y=20+12

y=32

y = 4x + 12

y = 4(8) + 12

y=32+12

y=44

the correct option for the given Equation at the different values of x will be C.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given y = 4x + 12, using the x-values, 3, 5, and 8.

To find the value of y, at x = 3, 5, and 8

Thus,

For x = 3

y = 4 * 3 + 12

y = 24

For x = 5,

y = 4 * 5 + 12

y = 32

for x = 8

y = 4 * 8 + 12

y = 44

therefore, the correct option for the given Equation at the different values of x will be C.

Step-by-step explanation:

1kg of grapes = $1.50

=> 3.5kg of grapes = $1.50 * 3.5 = $5.25

1kg of carrots = $1.00

=> 2.25kg of carrots = $1.00 * 2.25 = $2.25

Total cost = $5.25 + $2.25 = $7.50.
