-1.5(4-n)+2.8
multiply 4-n by -1.5
multiply to both the 4 and -n
-6+1.5n+2.8
add -6+2.8 since they are similar
-3.2+1.5n
1.5n-3.2
I believe this is the simplest form
Answer:
Step-by-step explanation:
The area is the product of the length and width
- The area = 7 1/6 m² = 43/6 m²
- The length = 3 1/3 m = 10/3 m
Width = ?
- A = lw
- w = A/l
- w = 43/6 ÷ 10/3 = 43/6 × 3/10 = 43/20 = 2 3/20 m
The width is 2 3/20 m
Answer:
6/5 or 1 1/5
Step-by-step explanation:
Each piece is 2/5 so you add it up 3 times or multiply by 3 to get 6/5 or 1 and 1/5.
Answer:
14 bags
Step-by-step explanation:
Dimension of lawn : 230 feet by 180 feet
area of rectangle is given by length * width
Since lawn is rectangular area of lawn = 230 feet * 180 feet = 41,400 sq. feet
Given that one bag of fertilizer covers 3000 square feet of lawn.
Thus , to find no. of bags required to cover whole lawn will be
total area of lawn/area which one bag of fertilizer covers
no. of bags required to cover whole lawn = 41,400 sq. feet/3000 sq. feet
= 13.8 bags.
As no. of bags cannot be fractional , hence rounding bag to nearest unit place is 14 bags.
Answer:
4.5
Step-by-step explanation:
4n - 6 = 12
add +6 to both sides
4n = 18
divide by 4
4/4n = 18/4
n = 4.5
