4 bananas and 3 peaches cost $10. We can represent this information as 4x +3y = $10. The x represents the cost of bananas and th
e y represents the cost of peaches.
a) Find an equation for 1 banana and 2 peaches cost $5
b) With the two equations, use a matrix method on your calculator to determine the cost of a banana and the cost of a peach.
1 answer:
Answer:
a x+2y =5
b x=1 y=2
Step-by-step explanation:
4x+3y = 10
So the cost of 1 banana is x and the cost of 1 peach is y
a) we want the cost of 1 banana and 2 peaches
1x+2y
That is equal to 5 dollars
1x+2y =5
x+2y =5
b
The matrixes are
1 2 x 5
* =
4 3 y 10
Using my calculator, x=1 y=2

A statement is something you are standing for and your sticking to it.
If the 5 scores have a mean of 8, then their total sum would be 8*5 = 40
Now if one score if added (let's call this score x), there are 6 scores and the mean changes to 9, thus:
(40 + x)/6 = 9
40 + x = 54
x = 14
