Mary runs in the Chicago marathon and it takes her 5 hours to complete it. Write a
or unit rate that could describe Mary's run if a marathon is 26.2 miles long.



Answers

Answer 1
If you want to keep it technical, the normal “/unit rate” for running is minutes per mile. You can use dimensional analysis like I did below to find the answer. You should get 11.45 min/mile or about 11 min 25 sec per mile

: Brianna’s teacher asks her which of these three expressions are equivalent to each other. Expression A: 6x + 4 Expression B: 12x + 4 Expression C: 5x + x + 4 Briana says that all three expressions are equivalent because the value of each one is 4 when x = 0. Do you agree or disagree with Brianna?

Answers

Answer:

I disagree with Brianna.

Step-by-step explanation:

Expression A: 6x + 4

6(0) + 4

4

6(1) + 4

6 + 4

10

6(2) + 4

12 + 4

16

Expression B: 12x + 4

12(0) + 4

4

12(1) + 4

12 + 4

18

12(2) + 4

24 + 4

28

Expression C: 5x + x + 4

5(0) + (0) + 4

4

5(1) + (1) + 4

5 + 1 + 4

10

5(2) + (2) + 4

10 + 2 + 4

16

It is true that when you substitute the “x” in each expression with 0, you get 4. However, when you sustitute a different number, like 1 or 2, you get completely different answers. In order for these expressions to all be equal, they have to all get the same answer each time. Yet, notice how both expressions A and C got the same answer every time. This is because when you simplify expression C, you get 6x + 4 (when you add together 5x and x). Therefore, expressions A and C will always be equivalent.

what is 23 – 7x + 6 + 8x = 26

Answers

Answer: x = -3

Step-by-step explanation: hope this helps

23 – 7x + 6 + 8x = 26

x + 29 = 26

x +  29 - 29 = 26 - 29

x = 26 - 29

x = -3

Answer:

x=-3

Step-by-step explanation:

23 – 7x + 6 + 8x = 26

Add the numbers to get,

29-7x+8x=26

Move the constant to the right,

29+x=26

Add the numbers to get,

x=26=29

Calculate the difference

x=26-29

Calculate,

x=-3

Barbara have after the 30 weeks?
$684
$660
B.
$636
$404

Answers

It would be $636 because 30 times 22 is 660 and since it’s $4 interest for every hundred you do 6 times 4= 24 and 660-24=636.

y-intercept: (0,-4)

x-intercept: (-9,0)

Step-by-step explanation:

To find the y and x intercepts, simply plug in 0 for x or y in the equation.

y-intercept:

[tex]-\frac{4}{3} x - 3y = 12[/tex]

[tex]-\frac{4}{3} (0) - 3y = 12[/tex]

[tex]0 - 3y = 12[/tex]

[tex]-3y = 12[/tex]

[tex]y = -4[/tex]

(0,-4)

x-intercept

[tex]-\frac{4}{3} x - 3y = 12[/tex]

[tex]-\frac{4}{3} x - 3(0) = 12[/tex]

[tex]-\frac{4}{3} x - 0 = 12[/tex]

[tex]-\frac{4}{3} x = 12[/tex]
