Answer: Andre picked 252 pounds of apples

Step-by-step explanation:

Let x = number of pounds of apple picked by Jane.

Let y = number of pounds of apple picked by Andre

Let z = number of pounds of apple picked by Maria

Andre picks three times as many pounds as maria. It means that

y = 3z

Jane picks two times as many pounds as Andre. It means that

x = 2y

The total weight of the apples is 840 pounds. It means that

x + y + z = 840 - - - - - - - - - 1

We will substitute z = y/3 and x = 2y into equation 1

2y + y + y/3 = 840

Cross multiplying with 3

6y + 3y + y = 2520

10y = 2520

y = 2520/10 = 252

x = 2y = 252× 2 = 504

z = y/3 = 252/3 = 84

Place the correct symbol, &lt; or &gt;, between the two numbers 11/18 17/24
evablogger [386]

For this case we must indicate the correct sign between the following numbers:

\frac {11} {18}\ and\ \frac {17} {24}

We have to:

\frac {11} {18} = 0.611111111111\\\frac {17} {24} = 0.708333333333

So, we have to \frac {17} {24}> \frac {11} {18}

Answer:

\frac {17} {24}> \frac {11} {18}

Answer and shown work for 5x + y = 10 -x - y = -2
konstantin123 [22]
Solve first equation for y: 
5x+y=10
y=10-5x. Plug this equation into second equation

-x-(10-5x)=-2
-x-10+5x=-2
4x=8
x=2 (plug x into first equation)

5(2)+y=10
y=0
