Answer:
We cannot find a solution to the system of equations.
a+b = 5.30
2a + 2b = 14
Step-by-step explanation:
Let a = the price of an apple
let b = price of an orange
a+b = 5.30
2a + 2b = 14
Multiply the first equation by 2
2a+ 2b = 10.60
Subtract the second equation
2a+2b = 10.60
-2a+2b = 14
---------------------------
0 = -3.40
This is never true so there is no solution
31/52 is greater because the pie as I imagine it would be cut into bigger slices than 37/64 because then the pie has to be cut into 64 pieces instead of 52
Therefore, 31/52 is bigger and greater
Answer:
One
Step-by-step explanation:
First, we need to check a triangle with these sides <em>is</em> possible. Since 4 plus 5 is 9, and 9 is less than 10, we can make a triangle with these sides.
To answer the question, we can only make one unique triangle. Why? They give us three lengths and a triangle has three sides.
<em>However</em>, if they are counting a triangle in different positions the answer will be greater. Since it would just be the same triangle, I am going with the answer of only one.
Answer:
x=1/2, y=4
Step-by-step explanation:
Double both sides of the top equation:
4x+6y=26
Now subtract boths sides of the second one from the first one:
(4x+6y) - (4x-y) = 26 - (-2)
7y = 28
so y = 4
4x-y=-2 so 4x-4=-2
4x=2
x=1/2
