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
Here, 1/7 = 3/4x + 1
3/4x = 1/7 - 1
3/4x = -6/7
x = -6/7 * 4/3
x = -2/7 * 4
x = -8/7
In short, Your Answer would be -8/7
Hope this helps!
If you don’t know what a number is, you should substitute it for x and make an equation with the information you have been given. This gives:
(x + 8) x 2 = x - 11
Then, solve:
2x + 16 = x - 11
2x = x -27
x = -27
This can then be checked by using the number in the original text.
-27 + 8 = -19
-19 x 2 = -38
-38 is 11 less than -27.
Hope this helps :)
The answer is 29 I put it in my scientific calculator
One way of doing this would be to look at the πr² as if it were a single term. Then we could divide both sides by πr², which leaves h = V/πr².
