If Gabrielle takes 19 minutes to run 2 miles then how much time does he take to complete 1 mile.

The above is the ‘b’ question.

We can get to know who long he takes to complete 1 mile taking the mean of the two in the double number line.

In this case it would be, the mean if 2 to get 1 and the mean of 19,

The mean of 2 is,

2miles / 2 = 1 mile.

And the mean of 19 mins is,

19 mins / 2 = 9.5 mins.

Hence, Gabrielle takes 9.5 mins to complete 1 mile.

Hope this helps you. Plz let me know if you have any doubts.

9.5 minutes because if she ran 2 miles in 19 minutes you would divide them both by 2 and 19/2=9.5

5+k/4=3 please explain thoroughly

Answers

To solve this equation, you must multiply by a denominator and then subtract to isolate a variable.

Remove the Denominator

Multiply by 4 on both sides of the equation.

[tex]\displaystyle 4(5 + \frac{k}{4}) = 4(3)[/tex]

[tex]\displaystyle 20 + k = 12[/tex]

Simplify

Subtract 20 from both sides to isolate the k.

[tex]20 - 20 + k = 12 - 20[/tex]

[tex]\boxed{k = -8}[/tex]

The final answer is k = -8.

The answers are:

Question 23: 140

Question 24: 25

Step-by-step explanation:

Question 23:

Since 25% is 1/4 of the total amount of members in the club, we need to multiply the amount of drum player (35), by 4.

35 x 4 = 140

Question 24:

The absolute value of -25 is 25, since the absolute value is the value without any signs.

Therefore, the answers are:

Question 23: 140

Question 24: 25

Question 23 is 140 because since there is 25% that would be 1/4 and you would divide by 4.

Question 24 is 25 I think.

Rachel bought 2.5 pounds of cookies for $13.40. Her friend buys 4.5 pounds of crackers for $24.75. Which is less
expensive per pound? By how much? (HINT: Find the unit rate for each, then find the difference)

Answers

Cookies: $13.40 divided by 2.5 = $5.36
Crackers: $24.75 divided by 4.5 = $5.50
Therefore, Cookies are less.
the answer would be the crackers are more expensive per pound and by $0.14. if you divide the price of the cookies by the amount of pounds you would come up with about $5.36 per pound. and if you do the same with the crackers it would be about $5.50 per pound.

i need to know the rest of the equation just letter R

Notice that 2/3 times 12 is...

(2/3)*12 = (2/3)*(12/1)

(2/3)*12 = (2*12)/(3*1)

(2/3)*12 = 24/3

(2/3)*12 = 8

So that explains the 8 on the right hand side.

For the blank, we'll multiply 2/3 by the 9y term like so

(2/3)*9y = ((2/3)*(9/1))y

(2/3)*9y = ((2*9)/(3*1))y

(2/3)*9y = (18/3)y

(2/3)*9y = 6y

This means 6y goes in the blank.

If your teacher only cares about the coefficient, aka number out front of the variable, then you'd just go for 6. That's my guess as to what your teacher wants. It seems to fit with the template you show and that would mean R goes in the second to last slot.

Also, for those types of worksheets you can ALWAYS find the answer key just by googling the the puzzle name!
