Answer:
X = 0 4 8 12
Y = 10 7 4 1
Step-by-step explanation:
Given:
Cost of one T shirt = $15
Cost of one sweater = $ 20
To find :
The graph that will represent both number of T-shirts and sweatshirts = ?
Solution:
Let the number of t-shirts be x
The number of sweaters be y
They want to rise a found of $200
Then the equation to represent this situation is
15x + 20y = 200
By trial and error method
15(12) + 20(1) = 200
15(8) + 20(4) = 200
15(0) + 20(10) = 200
15(4) + 20(7) = 200
Answer with Step-by-step explanation:
A 3 foot wide brick sidewalk is laid around a rectangular swimming pool.
The outside edge of the sidewalk measures 30 feet by 40 feet.
Length of swimming pool=(30-3-3) feet
=24 feet
Breath of swimming pool=(40-3-3) feet
= 34 feet
Perimeter of swimming pool=2(24+34) feet
(since perimeter of rectangle=2(l+b) where l is the length and b is the breath of the rectangle)
Perimeter of swimming pool=116 feet
Hence, Perimeter of swimming pool is:
116 feet
