Kevin sold 10 pounds of apples and 20 pounds of raspberries.
Step-by-step explanation:
Given,
Cost per pound of apples = $3.50
Cost per pound of raspberries = $4
Total amount earned = $115
Let,
x represent the pounds of apples sold
y represent the pounds of raspberries sold
According to given statement;
3.50x+4y=115 Eqn 1
y = 2x Eqn 2
Putting value of y from Eqn 2 in Eqn 1

Dividing both sides by 11.50

Putting x=10 in Eqn 2

Kevin sold 10 pounds of apples and 20 pounds of raspberries.

Answer:
8x-8
Step-by-step explanation:
if Lana is X year
then that makes Yan 3X-4
the father is twice the sum of their ages
3X-4+X=4X-4
the father being twice
his age should be
8X-8
Volume=length*width*height
Volume=9 1/4*4*2 1/3
H=vt-16t²
vt-16t²=H
vt=16t²+H
v=(16t²+H)/t
v=16(t²/t)+H/t
v=16t+H/t
Answer: the answer would be: v=16t+H/t
