To work this one out, you want to divide 10 1/2 by 3/4 right? So to do that, you want to change 10 1/2 to an improper fraction (21/2) and multiply it by 3/4’s reciprocal (4/3) and use cancellation to get the answer 14. Attached is an example of how to work it out on paper.

17. You have $850 to buy new carpet for the game room. The dimensions of the game

gregori [183]

Answer:

Cost of new carpet per square foot should be less than or equal to $3.54.

Step-by-step explanation:

Given:

Money have to buy carpet = $\$850$

dimension of game room is 20 feet by 12 feet

So we can say length l = 20 feet

and width w = 12 feet

let $x$ be the cost per square foot for new carpet.

Assuming game room to be rectangular in shape we will find the area of it.

Area of room = $length \ l \times width \ w = 20 ft\times 12 ft = 240 \ ft^2$

Total area $\times$ cost per square feet ≤ Total money we have

Hence,

$240 \ ft^2 \times x \leq \$850\\\\x\leq \frac{\$850}{240 \ ft^2}\\\\x\leq \$3.54 \ per \ ft^2$

Hence Cost of new carpet per square foot should be less than or equal to $3.54.

Answer:

x =7, y = 0

Step-by-step explanation:

$2x - 9y = 14...(1) \\ \\ x = - 6y + 7...(2) \\ \\ from \: equation \: (1) \: and \: (2) \\ \\ 2( - 6y + 7) - 9y = 14 \\ \\ - 12y + 14 - 9y = 14 \\ \\ - 21y = 14 - 14 \\ \\ - 21y = 0 \\ \\ y = \frac{0}{ - 21} \\ \\ \huge \red{ y = 0} \\ \\ x = - 6 \times 0 + 7 \\ \\ x = 0 + 7 \\ \\ \huge \purple{x = 7}$
