Answer:
(2, 0)
Step-by-step explanation:
Given the simultaneous equation
2x-y = 4
3x+y = 6
Add both equation
2x+3x = 4 + 6
5x = 10
x = 10/5
x = 2
Substitute x = 2 into equation 1
From1 ;
2x-y = 4
2(2) - y = 4
4 - y = 4
y = 4-4
y = 0
Hence the solution to the system of equation is (2, 0)
Divide 2.48 by 10 to find the price of 1 slice. = 0.248
Do the same with the other price.
3.18 / 12 = 0.265
The best one to get would be the 10 cheese slices because a single slice is cheaper than the single slices for the 12 slices.
hope this helped! (:
A: apples
b: bananas
Your expression could be:
$0.80a + $0.60b = $10.00
----
$0.80 ( 8 ) + $0.60 ( 6 ) = $10.00
$6.40 + 3.60 = $10.00
$10.00 = $10.00
