Answer:
54 foot long pieces
Step-by-step explanation:
Jack has 18 yards of fabric that he wants to cut into pieces that are each 1 foot long. How many one-foot long pieces can Jack create? Come up with two different strategies for solving. (1 yd = 3 ft)
Step 1
Convert yards to foot
1 yd = 3 ft
18 yards = x
Cross Multiply
x = 18 × 3 ft
= 54 ft
Step 2
He wants to cut into pieces that are each 1 foot long. How many one-foot long pieces can Jack create?
This is calculated as:
1 foot = 1 piece.
54 feet = x
x = 54 × 1 piece
x = 54 pieces
Answer:
Step-by-step explanation:x+y+z=100(let x ,y,z represent the first second and third numbers respectively)
Therefore,y=2z
z=x-8
y=2x-16
substituting the values of x,y and z into the question,we have
x+(2x-16)+(x-8)=100
Simplifying,we have
4x-24=100
adding 24 to both sides of the equation,
4x=100+24
4x=124
dividing both sides of the equation by the co-efficient of x,we have
4x/4=124/4
4.31=124
therefore,x=31.
I am not positive for the factoring of each expression but for the distributive property you do 8 TIMES x then 8 times 7 so you would get blank plus blank and so on for the next ones.
