We use a system of equations to solve this. Since tri city sells 4 times it becomes 4x and solly company is x. Then we do 4x-x=96. 3x=96. x=32. We are not finished yet. We still have to multiply x by 4. x=128. Tri City sold 128 dishwashers.

John runs the same amount each day (r). If he runs for 4 days this week write an expression to represent the amount he ran this

AnnyKZ [126]

Answer:

$r \cdot 4 = z$

Step-by-step explanation:

An expression means that we don't know enough to create an equation. So, this means we will mostly be using variables.

John runs r amount every day. We need to create an expression for if he runs r amount for 4 days.

$r \cdot 4 = z$

r = how much he runs per day

4 = how many days he runs

z = how much he runs this week

This is your expression!
