The first onee
because you have to multiply the 3 by x &’ 5
First, divide the fractions into a decimal format.
8/3=2.667
-11/3=-3.667
Second, find the placement of the decimal.
The total length was 6 m.
One of the tables was 1.8 m
Subtract 1.8 from 6 to find the total length of the other two tables:
6 - 1.8 = 4.2m
The other two tables are the same size, so now divide 4.2 m by 2:
4.2 / 2 = 2.1
The other tables are 2.1 m long.
499 - 100%
599 - x
x = 599*100/499 = 120.04
x-100% = 120.04-100 = 20.04
Answer: The price increased by 20%.
This is a problem using the Pythagorean theorem.
The square of the length required is 122 + 122 + 302 = 1188
The length is the square root of this number; I will leave it to you to extract the square root.
