Answer:
Therefore the required result is 9x-2y =0.
Step-by-step explanation:
Given equation are
x-3y =6.....(1)
-8x-y=6 .....(2)
Subtracting equation (2) from (1)
x - 3y = 6
-8x - y= 6
+ + - [ The sign of equation (2) will be change in case of
_________ subtraction and in case of plus the signs remains same ]
(x+8x)-3y+y=6-6 [ adding the like terms]
⇒9x-2y =0
Therefore the required result is 9x-2y =0.
First set up a proportion
240/160 = 320/200
Cross multiply and if the left equals the right it is similar.
X = k x y
21 = k x 3
k = 7
x = 7y
x = 7(10)
x = 70
Answer: Food Saver
Step-by-step explanation:
A 5-pound bag at Bargain Mart costs $6.45. The coat per pound will be:
= $6.45 / 5
= $1.29
A 2-pound bag at Food Saver costs $2.50. The cost per pound will be:
= $2.50 / 2
= $1.25
A 7-pound bag at Grocery Surplus costs $9.45. The cost per pound will be:
= $9.45 / 7
= $1.35
A 10-pound bag at Economart costs $12.89. The cost per pound will be:
= $12.89 / 10
= $1.289
Therefore, the shop which sells flour for the lowest unit price is Food Saver.
