The math club is baking pies for a bake sale the fruit pie recipe calls for twice as many peaches as nectarines if it takes a total of 168 pieces of fruit for all the pies, how many nectarines are needed?

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

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
