One spool contains ​ 4 2/3 ​ yards of twine. A second spool contains 11 feet of twine.
frez [133]

Answer: The correct answer is option (C); 25 feet

Step-by-step explanation: The standard of conversion between feet and yards is given as;

3 feet = 1 yard.

In other words, in every yard you will find times 3 feet. So in a spool of twine that contains four and two-thirds (4 2/3) yards of twine, conversion to feet would be given as;

X feet = (4 2/3) x 3

X feet = (14/3) x 3

X feet = 14

For the second spool the measurement is 11 feet of twine, so the total measurement would be derived as,

Spool 1 + Spool 2 = Total

14 + 11 = Total

25 = Total

Hence, the total measurement of twine would be 25 ft.

What are the coordinates of the image of vertex D after a reflection across the x-axis?
Elena-2011 [213]

Answer:

(-3,5) ia the answer

Step-by-step explanation:

It is because when you reflect it across the x axis the first coordinate will be negative and the second number is positive since its in the second square of the graph, so it is more of a resonable guess.

If (x+3)divided by 3 = 9 what is x
defon

Answer:

x = 24

Step-by-step explanation:

Given that:

(x+3)/3 = 9

multiplying both sides by 3

(x+3) = 9*3

(x+3)= 27

Subtracting 3 from both sides

x= 27-3

x=24

I hope it will help you!
