A factory makes rods by cutting plastic pipes that are 4 feet long into 7 equal-sized rods. How long is each rod? (enter your answer as a fraction or a mixed number) What is the total length of 15 rods? (enter your answer as a fraction or a mixed number)

4/7

Step-by-step-- It is given that we have cut the 4 ft long.

We have to make it into 7 times it's original piece.

To determine this Is the length of the new rods.

Let the length of each new rod be x.

We need 7 rods-

7x = 4 ft

1 = 4/7x

x = 4x/7x

So, x gets cancelled. Now, we get the answer as . 4/7

hope this helped..:))

4/7

Step-by-step explanation:

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
