Jack is putting up new shelves. He is using pieces of wood as shown below. measures 3 1/5 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 24 1/5 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 2 3/4 kilograms (kg). Jack used between 1/2 and 3/4 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.

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
