Okay i just pmed you, willing to help just can't see the picture at all that well
The answer is 6.5 and what I did is I took the mixed fraction (2 2/4) and I turned It into a decimal. After I knew it was 2.5 all I had to do was use the formula A=lw to get my answer on what the width was.
Step 1: Replace the variables with numbers
A=lw
A=2(1.25)
A= 2.5 (Fraction 2 2/4)
Step 2: Use the perimeter formula (P=l+w+l+w or P=(l+w)2)
P=(l+w)2
P=(2+1.25)2
P=(3.25)2
P=6.5
Answer is 6.5 I hope this helped ^^
Stack 1 : 2^0 = 1 quarter.
Stack 2 : 2^1 = 2 quarters.
Stack 3: 2^2 = 4 quarters.
Stack 4: 2^3 = 8 quarters.
Stack 5 : 2^4 = 16 quarters.
Stack 6: 2^5 = 32 quarters.
1 + 2 + 4 + 8 + 16 + 32 = 63
Answer: She used 63 quarters.
Answer at the bottom
Step 1: Simplify both sides of the equation.
4x−7x=34−55
4x+−7x=34+−55
(4x+−7x)=(34+−55)(Combine Like Terms)
−3x=−21
−3x=−21
Step 2: Divide both sides by -3.
−3x
−3
=
−21
−3
x=7
Answer:
x=7
