Let x be the amount of apples that Kevin bought.
It says that john buys three more than twice the amount of apples that kevin buys, so 3 + 2x apples.
They bought 21 apples total, so x + 3 + 2x=21
Collecting like terms gives 3x+3=21
Subtracting 3 from both sides gives 3x=18 and then dividing both sides by 3 gives x=6
x is the amount of apples kevin bought, so kevin bought 6 apples
Answer:

Step-by-step explanation:
Here, we want to get the distance between the two points as follows;
CD = √(x2-x1)^2 + (y2-y1)^2
So we have;
CD = √(7+8)^2 + (-5+4)^2
CD = √225+ 1 =
CD = √(226
CD = 15.0 units
Answer:
69
Step-by-step explanation:
To find the lateral surface area of a pyramid, you can find the area of each triangle, A = 1/2bh or A = 1/2lw, then multiply by the number of triangles, which would be based on the number of sides of the base; or you can take half the perimeter and multiply by the slant height.
