The length of a rectangular poster is 3 inches less than the width. The perimeter is 38 inches. Find the length
Answers
Answer: Breadth = 11 ; Length = 8
Step-by-step explanation:
Let the width of the rectangle be 'x'
Length of the rectangle = x - 3
Perimeter of the rectangle = 38
Perimeter of rectangle formula = 2 ( length + breadth )
Substitute:
2 ( x + x-3 ) = 38
2 ( 2x - 3 ) = 38
2x - 3 = 19
2x = 19 + 3
2x = 22
x = 11
Therefore, the breadth = 11
Length = x-3 = 11 - 3 = 8
To check, find the perimeter:
2( 11 + 8)
= 2 ( 19 )
= 38.
We get the same perimeter so the answer is correct.
Answer:
length =8
Step-by-step explanation:
x= width
x-3(3 inches less than the width)
x+x-3+x+x-3=38
4x-6=33. add 6 on both sides
4x=44 divide by 4
x=11. plug 11 in for x because 11 is the width. in the equation x-3. (x=width) 11-3= 8. The length is 8.

Find out the how many plants will be in each row.
To prove
Let us assume that the number of plants in each row be x.
As given
Gavin buys 89 blue pansies and 86 yellow pansies
he will plant the flowers in 5 rows with an equal number of plants in each row.
Total number of flowers Gavin buys = 89 + 86
= 175
The number of plants in each row
x = 35
Therefore the number of plants in each row be 35 .
The Answer is 35 because if you divide 89 by 5 it gives you 17.8 and 86 by 5 gives you 17.2. When you round 17.2 it is still 17 and 17.8 is 18. And 17+18=35
35*5=175
89+86=175
