Answer:
The price of 1 pound of apple = $ 3
The price of 1 pound of berries = $ 8
The price of 1 pound of cherries = $ 5
Step-by-step explanation:
Let the price of 1 pound of apple be x
The price of 1 pound of berries be y
The price of 1 pound of cherries be z
So,
2 x + y + 4 z = 38 --------------1
3 x + 2 y + 2 z= 35 -------------------2 (Corrected from source)
5 x + 3 y + 2 z = 49 ------------3
Solving the equations, we get that:
x = 3, y = 8, z = 5
Answer:
A. ) d = 0.7 x $2.40
Step-by-step explanation:
too easy XD
First you should simplify:
2m - 2/10 * 2*m = 2m - 2/5m = 10/5m - 2/5m = 8/5m
and now you can say: 8(m/5) = 8/5m
so they are equivalent :)))
i hope this is helpful
have a nice day
To graph
graph the point (3,6)
yintercept is on the y axis so go up 2 units from the origin and plot the point (0,2)
now the parabola
we know it has to go through points (3,6) and (0,2)
therefor we now that it opens down
we also knwo that the vertex's y value is the axis of symmetry
so we also put a point at (6,2)
draw a parabola opening down through the points (0,2) (3,6) (6,2), with (3,6) at the top/peak
see attachment
That would be 48 inches. 4 x 12 = 48
