Answer: Andre picked 252 lbs of apple
Step-by-step explanation:
Let x represent the number of pounds of apple that Jane picked.
Let y represent the number of pounds of apple that Andre picked.
Let z represent the number of pounds of apple that Maria picked.
Andre picks 3 times as many pounds as maria. This means that
y = 3z
z = y/3
Jane picks 2 times as many pounds as Andre. This means that
x = 2y
The total weight of the apples 840 ibs. This means that
x + y + z = 840 - - - - - - - - - -1
Substituting z = y/3 and x = 2y into equation 1, it becomes
2y + y + y/3 = 840
Cross multiplying by 3, it becomes
6y + 3y + y = 2520
10y = 2520
y = 2520/10 = 252
x = 2y = 2×252 = 504
z = y/3 = 252/3 = 84
Answer:
Take the square root of both sides of the equation.

A star is written to show multiplication. It is a replacement for a dot or a x which is what you probably learned to be the "times" sign. In upper level maths, the "x" is replaced with a " * " to make it more legible and to avoid confusion with the variable "x".
Answer:
x=6
Step-by-step explanation:
When we multiply exponents with the same base we add the exponents
When we divide exponents with the same base we subtract the exponents
4^3 * 4^3 ÷4^3 *4^3
We will work from left to right
Multiply means add
4^(3+3) ÷4^3 *4^3
4^6÷4^3 *4^3
Now divide means subtract
4^6÷4^3*4^3
4^(6-3)*4^3
4^3 *4^3
4^3*4^3
Multiply means add
4^(3+3)
4^6
4^6 = 4^x
The bases are the same so the exponents must be the same
x=6
