Answer:112 nectarines are needed.
Step-by-step explanation:
The math club is baking pies for a bake sale and they would require a number of peaches and nectarines
Let x represent the number of peaches.
Let y represent the number of peaches.
The fruit pie recipe calls for twice as many peaches as nectarines. This is expressed as
y = 2x
if it takes a total of 168 pieces of fruit for all the pies, it means that
x + y = 168 - - -- - - - - - 1
Substituting y = 2x into equation 1, it becomes
x + 2x = 168
3x = 168
x = 168/3 = 56
y = 2x
y = 2×56 = 112
