Convert the rate 1000 fluid ounces per 2 hours to cups per minute.

Answers

The conversion may be done through the dimensional analysis and the use of proper conversion factors. Each fluid once is 0.125 cup and each hour is equal to 60 minutes.
(1000 fluid ounces / 2 hours) x (0.125 cup / 1 fl oz.) x (1 hr / 60 min) = 2.08 cup/ minute

Thus the conversion is 2.08 cup / minute.

At the bank,Brent exchanges $50 in bills for 50 one dollar coins.The total mass of the coins is 405 grams.Estimate the mass of 1 one dollar coin

Answers

Data:

$50 dollars in bills → 50 coins of one dollar

Estimate the mass of one dollar coin
Solving:

50 coins → 405 grams
1 coin → x

The rule of three

50*x = 405*1
50x = 405
$x = (405)/(50)$
$x = 8,1$
We have:

$\boxed{x \approx 8grams/coin}$

405/50=8.1grams
if asked to simplify the answer would be 8 grams per coin

I do not know which formula to useCarla bought a dress at a sale for 20% off the original price. The sale price of the dress was $68.90. Find the original price of the drees, in dollars.

Step by step explanation please.

Answers

Answer:

I think it's the second formula.

Step-by-step explanation:

Let x be the original price.

The discount rate is 20%

Sale Price is $68.90

Discount = 20% of x = 0.2x

Using the formula, Sale Price = Original Price - Discount,

Original Price - Discount is x-0.2x = 0.8x

$68.90 = 0.8x

From here on, just do the equation :) Hope this helps!

Use the 3rd one because it has fewer steps and will give you the answer

Which value of x makes the following equation true?4(x - 1) = -4x + 60

A. 8
B. 12
C. 11
D. 9

Answers

The easiest way is to just solve the equation.
4x - 4 = -4x + 60
4x + 4x = 4 + 60
8x = 64
x = 8

A slower way to do this is to plug each of the numbers into the equation to see which makes the equation is true.
So for A.
4(8 - 1) = -4(8) + 60
4(7) = -32 + 60
28 = 28
Fortunately, this is true, so A is the answer and you don't have to try the other options.

It would be A because if you plug in 8 for x on each side you get 28 which makes the equation true

Solve the following system of equations for all three variables.5x−2y+z = 8
−9x+2y+2z = 5
−9x−2y−5z = 4

Answers

  5x - 2y + 1z = 8 ⇒   5x - 2y + 1z = 8
-9x + 2y + 2z = 5 ⇒ -9x + 2y + 2z = 5
-9x - 2y - 5z = 4 -4x + 3z = 13

5x - 2y + 1z = 8
-9x + 2y + 2z = 5 ⇒ -9x + 2y + 2z = 5
-9z - 2y - 5z = 4 ⇒ -9x - 2y - 5z = 4
-18x - 3z = 9

-4x + 3z = 13
  -18x - 3z =   9
-22x = 22
  -22 -22
  x = -1
  -18x - 3z = 9
-18(-1) - 3z = 9
18 - 3z = 9
- 18 - 18
-3z = -9
-3 -3
z = 3

5x - 2y + z = 8
5(-1) - 2y + 3 = 8
-5 - 2y + 3 = 8
-2y - 5 + 3 = 8
-2y - 2 = 8
  + 2 + 2
  -2y = 10
-2   -2
y = -5
  (x, y, z) = (-1, -5, 3)
