6 0

Step-by-step explanation:

a. Area = 121 ft²

s² = 121

s = √121

Therefore s = 11 ft

b. Area = 81 yd²

s² = 81

s = √81

Therefore s = 9 yd

c. Area = 324 cm²

s² = 324

s = √324

Therefore s = 18 cm

d. Area = 361 mi²

s² = 361

s = √361

Therefore s = 19 MI

Simple...

you have: 8x-6y=1

You're trying to find m-->>using y=mx+b to re-write the line....

8x-6y=1

8x-6y=1
-8x      -8x

-6y=-8x+1

\frac{-6y}{-6} = \frac{-8x+1}{-6}

y=\frac{4}{3} x- \frac{1}{6}

Your slope m=\frac{4}{3} x

Thus, your answer.

A used-car dealer sold one car at a profit of 25 percent of the dealer's purchase price for that car and sold another car at a l
Daniel [21]

Answer:

C. 1000 loss.

Step-by-step explanation:

Let x represent purchase price of each car.

We have been given that a used-car dealer sold one car at a profit of 25 percent of the dealer's purchase price for that car and sold another car at a loss of 20 percent of the dealer's purchase price for that car.

We can represent the car that dealer sold with 25% profit to find purchase price as:

x+0.25x=20,000

1.25x=20,000

\frac{1.25x}{1.25}=\frac{20,000}{1.25}

x=16,000

Therefore, the purchase price of 1st car was $16,000.

We can represent the car that dealer sold with 20% loss to find purchase price as:

x-0.20x=20,000

0.80x=20,000

\frac{0.80x}{0.80}=\frac{20,000}{0.80}

x=25,000

Therefore, the purchase price of 2nd car was $25,000.

The total purchase price of both cars would be 16,000+25,000=41,000

The total sale price of both cars 20,000+20,000=40,000.

We can see that the sale price of both car is less than purchase price by $1000, so the dealer got a loss of $1000.

Therefore, the dealer's total loss, in dollars, for the two transactions combined was 1000 and option C is the correct choice.
