Answer 1

Answer:

Friday:

$30x + 20y = 910$

Saturday:

$45x + 30y = 1365$

$30x + 20y = 910$

$30x = 910 - 20y$

Divide both sides by 30:

$x = (910 - 20y)/(30)$

Simplify the fraction:

$x = (91 - 2y)/(3)$

(It is impossible to solve for specific values for x and y as seen in part c, so I'm not sure what the question is asking to solve for.)

$45x + 30y = 1365$

Substitute x = (91-2y)/3 in that equation (which is Saturday's equation)

$45 * (91 - 2y)/(3) + 30y = 1365$

$15(91 - 2y) + 30y = 1365$

$1365 - 30y + 30y = 1365$

$1365 = 1365$

Hence, there is an infinite amount of solutions for x and y.

How do you divide 1 quart into 3 containers ?

Answers

The US customary system is a horrible, horrible thing.
We want to divide this quart into 3 containers using customary units.
Let's look at smaller customary units and see how that does us.

1 quart = 2 pints, so
1/3 quart = 2/3 pint.
We still don't have whole numbers, so let's keep going.

1 pint = 2 cups, so
2/3 pint = 4/3 cup.
Since we have a whole cup now, we leave that and keep going with the 1/3 c.

1 cup = 8 fluid ounces, so
1/3 cup = 8/3 fl. oz.
8/3 fl. oz. = 2 fl. oz. + 2/3 fl. oz.
Can you see where this is going?

1 fluid ounce = 2 tablespoons, so
2/3 fl. oz. = 4/3 Tbsp.
4/3 Tbsp. = 1 Tbsp. + 1/3 Tbsp.

1 tablespoon = 3 teaspoons, so
1/3 Tbsp. = 1 teaspoon! YES!

So our answer is 1 cup, 2 fluid ounces, 1 tablespoon, and 1 teaspoon.
(if you wanted that all in one unit, it'd have to be 64 tsp.)

If Taryn and Alistair want to earn an additional $735 each , how many hours will each spend mowing lawns

Answers

If Taryn mowed 9 lawns in 7.5 hours and earned $112.50, then her hourly rate is:

$112.50 / 7.5 hrs = $15 per hour

If Alistair mowed 7 lawns in 5 hrs and earned $122.50, then her hourly rate is:

$122.50 / 5 hrs = $24.50 per hour

To earn an additional $735 each, they should work the following hours.

Taryn: $735 / $15 = 49 hours

Alistain: $735 / $24.50 = 30 hours

Taryn and Alistair will each spend 49 hours mowing lawns to earn an additional $735 each.

To find out how many hours Taryn and Alistair will each spend mowing lawns to earn an additional $735 each, we need to divide $735 by their hourly rate. Let's assume their hourly rate is the same for both of them. If their hourly rate is $15, then dividing $735 by $15 gives us 49. Therefore, Taryn and Alistair will each spend 49 hours mowing lawns to earn an additional $735 each.
