PLEASE HELP I WILL MARK BRAINLIEST Jack is putting up new shelves. He is using pieces of wood as shown below.

Each piece of wood measures meters long. Jack has 8 pieces of wood that are the same length.

A. Write an equation to show how to find the total length, in meters, of the 8 pieces of wood.

Jack said that the total length of the 8 pieces of wood is meters. Is Jack correct? Why or why not?

B. Along with the wood, Jack is also using some nails to build the shelves. One box of nails has a mass of kilograms (kg).

Jack used between and of the nails in the box.

How many kilograms of nails did Jack use to build the shelves? Show your work or explain your answer.
Type your answer in the box below. Make sure to label each part with A and B.

answer:

your answer is: c. 196 7/8 in^3.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.

i think it’s c i believe

step-by-step explanation:

given the 2 equations

- x + y = - 2 → (1)

2x - 3y = 4 → (2)

multiplying (1) by 2 and adding to (2) will eliminate the x- term

- 2x + 2y = - 4 → (3)

add (2) and (3) term by term

(2x - 2x) + (- 3y + 2y) = (4 - 4), simplifying gives

- y = 0 ⇒ y = 0

substitute y = 0 in either of the 2 equations for corresponding value of x

substituting in (2) gives

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 ) → a
