Eleanor and Max used two Rectangular wooden boards to make a set for the school play one board was 6 feet long,And other was 5 1
/2 feet long the two boards had equal widths. The total area of the set was 60 3/8 square feet. what is the width
1 answer:
The total area is the product of length and width
... total area = (length1 × width) + (length2 × width)
... = (length1 + length2) × width
... 60 3/8 = (6 + 5 1/2) × width
... (60 3/8)/(11 1/2) = width = 5 1/4 . . . . feet
The width of the boards use for the set was 5 1/4 feet.
_____
A suitable calculator can give you this answer directly. Others may ask you to convert to or from decimal feet.
___
The method conventionally taught to do division with mixed numbers is to convert them to improper fractions:
... 60 3/8 = (60·8 +3)/8 = 483/8
... 11 1/2 = (11·2 + 1)/2 = 23/2
Then, invert the denominator and multiply:
... (483/8)/(23/2) = (483/8) × (2/23) = 483/(4·23)
... = 483/92 = 5 23/92 = 5 1/4 . . . . . . . . remembering that 92 = 4·23
_____
It isn't clear whether this is a problem about areas, or a problem about mixed-number arithmetic. It is a good idea to get comfortable with arithmetic using numbers in any form: integers, decimals, mixed numbers, fractions, percents.

Answer:
A = 3/2
B = 3
C = 6
D = 12
Step-by-step explanation:
Simply plug it in. When you have a negative exponent, you basically switch the sign of the exponent and put a one over the number itself.
- So we have 2^-1. This is the same as
= a
- Now do
= b
- Then do
= c
- Finally do
= d
Answer:
#6 is 17 days
Step-by-step explanation:
This is how I answered it
1) 2750 = 550 + 125x
2) subtract 550 from each side
2750-550=2200
so the left over equation is:
2200 = 125x
3) divide each side by 125 to get x by itself
2200÷125= 17.6
4) you are left with: x = 17 days
