Answer:
56 number of Nectarines are needed
Step-by-step explanation:
Let number of Fruit-pie be x and number of nectarines be y.
Since the fruit pie recipe calls for twice as many peaches as nectarines.
then we have,
It is also given that total of 168 pieces fruit for all pies.
⇒
Substitute x=2y in above equation to solve for y:
or
3y=168
Divide both sides by 3, we get
Simplify:
y = 56
Therefore, 56 nectarines are needed.
Answer:
Value of y = 7
Step-by-step explanation:
By the midpoint theorem of the triangles,
"Segment joining midpoints of the two sides of a triangle is parallel to the third side and measure half the length of the third side."
Therefore, from the figure attached,
In ΔFGH,
J and K are the mid points of the two sides GH and FH.
By theorem, segment JK║GF and m(JK) =
(5y + 3) = 2(2y + 5)
5y + 3 = 4y + 10
5y - 4y = 10 - 3
y = 7
