U first set the fraction : 6700/20.

U can cancel out the zeroes, to get 670/2.

well it has to be grater because if you know that when dividing you must do bigger divided by smaller it can't be the other way around

9x1x5= & I have to use parentheses

Answers

(9 x1) x 5 = 9 x 5 = 45

9 x (1 x 5) = 5 x 9 = 45

So it doesn't matter where the parentheses were suppose to go as you can see I worked it both ways and the answer is the same.

Hope this helps you. :-)

You can place the parentheses anywhere cause if you do (9x1)5 it will equal 45. And if you do (5x1)9 it will also be 45. So where ever you put it , it will equal the same amount. But, jus in case next time asked your teacher or friends for further help.

The soccer team is selling keys chains to raise money for the team. They ordered 100 key chains that cost $0.25 each. There is a flat shipping rate of $8. The team sells the key chains for $2 each. Write an algebraic inequality to find the fewest number of key chains,k, the team must sell to make the profit. What is the fewest number of key chains the team must sell to make a profit? Show your work and explain your thinking.

Answers

The formula to get the correct answer to question is this:

1.) To get the total cost of goods bought:
((100 key chains) x ($0.25 purchasing cost)) + ($8 shipping rate) = $33
Which means each key chain essentially costs $0.33 each
2.) To get the number of units they should sell to make profit:
Breakeven = Costs/Price meaning $33/$2 = 16.5
They should sell 16.5 units to make a profit.
