Danny charges $35 for 3 hours of swimming lessons.Martin charges $24 for 2 hours of swimming lessons. Who offers a better deal?

Answers

Answer 1

Answer:

Answer:

Danny offers better deal .

Step-by-step explanation:

As given

Danny charges $35 for 3 hours of swimming lessons.

$Cost\ of\ one\ hour = (Total\ cost)/(Total\ hours)$

$Cost\ of\ one\ hour = (35)/(3)$

Cost of one hour = $ 11.67 (Approx)

Martin charges $24 for 2 hours of swimming lessons.

$Cost\ of\ one\ hour = (Total\ cost)/(Total\ hours)$

$Cost\ of\ one\ hour = (24)/(2)$

Cost of one hour = $ 12

As the cost charge by Danny for one hour is less as cost charge by Martin .

Therefore Danny offers better deal .

Answer 2

Answer:

Danny charges about 11.67 per hour

Martin charges about 12 per hour

So, Danny offers a better deal.

no solutions

Answers

Answer:

D. No solutions.

Step-by-step explanation:

We have been given a system of equations and we are asked to find the solution set for our given system.

$y=x^2-4x-21$

$y=-5x-22$

To find the solution for our given system we will equate our both equations as:

$x^2-4x-21=-5x-22$

$x^2-4x+5x-21=-5x+5x-22$

$x^2+x-21=-22$

$x^2+x-21+22=-22+22$

$x^2+x+1=0$

We will use discriminant formula to check for the solution of our given system.

$√(b^2-4ac) \geq 0$ for real solutions.

Upon substituting our given values in above formula we will get,

$√(1^2-4*1*1) \geq 0$

$√(1-4) \geq 0$

$√(-3) \ngeq 0$

Therefore, our given system has no solutions and option D is the correct choices.

-2 + (-1/3) equals what?

Answers

Answer:

-2 $(1)/(3)$

Step-by-step explanation:

Final answer:

To evaluate -2 + (-1/3), subtract -1/3 from -2, which simplifies to -7/3.

Explanation:

To evaluate -2 + (-1/3), we need to add the two numbers together. When adding negative numbers, we can think of it as subtracting the numbers.

So, -2 + (-1/3) is the same as -2 - 1/3. To subtract fractions, we need to have a common denominator.
The common denominator of 2 and 3 is 6, so -2 - 1/3 is equal to -12/6 - 2/6.
Subtracting -12/6 - 2/6 gives us -14/6. But we can simplify this fraction by dividing both the numerator and the denominator by their greatest common factor, which is 2. So, -14/6 simplifies to -7/3.
