100 feet
To find the total length of the entire string you multiply 8 times 5 and get 40.
To convert into feet multiply by 3 and get 120 feet. 
To find the total amount of string he uses, multiply 4 times 5 and get 20. It is already in feet.
Next you subtract 120 - 20 and get 100 feet, the total amount of string he has left.

7 1⁄5 – 6 2⁄5 = ? <br><br> A. 4⁄5<br> B. 1 4⁄5<br> C. 1 1⁄5<br> D. 13 3⁄5
STatiana [176]

Answer:

A

Step-by-step explanation:

Change the mixed numbers to improper fractions

7 \frac{1}{5} = \frac{36}{5}

6 \frac{2}{5} = \frac{32}{5}

The subtraction is then

\frac{36}{5} - \frac{32}{5}

Both fractions have a common denominator so subtract the numerators leaving the denominator

= \frac{36-32}{5} = \frac{4}{5} → A

Help meeee!!!!!!!!!!!!!!!!!!!
Ivenika [448]

Answer:

Y=-2x

When x= -6 then y =12

Step-by-step explanation:

If y and x in direct variation then y=c*x for some constant c.

We are told

-4=c2

——> c= -2

So y= -2x

When x= -6 this becomes

Y= (-2) * (-6)

——> y = 12
