Answer:

X = 2 , Y = 3

Step-by-step explanation:

Equation 1

x=y-1

Equation 1

x -y = -1

Equation 2

x+2y=8

Multiply equation 2 by equation -1

-x-2y= -8

By elimination method

x -y = -1

- x-2y= -8

-3 y = - 9

Y = 3

Put Y = 9 in equation 1

X - Y = -1

X -3 = -1

X = 3 -1

X = 2

X = 2 , Y = 3

Using the together rate, it is found that if Mrs Adams camps alone, she will use all the water in 24 hours.

<h3>What is the together rate?</h3>

The together rate is the sum of each separate rate.

In this problem, the rates are:

Together: 1/8.

Mr Adam: 1/12.

Mrs Adams: 1/x.

Hence:

$\frac{1}{12} + \frac{1}{x} = \frac{1}{8}$

$\frac{x + 12}{12x} = \frac{1}{8}$

$12x = 8x + 96$

$4x = 96$

$x = \frac{96}{4}$

$x = 24$

If Mrs Adams camps alone, she will use all the water in 24 hours.

Masteriza [31]

Answer:

My best solution would be 10053. Although this doesn't seem correct. The reason on why I got this is because of 16 being the diameter. When volume needs a radius and a height. So its this answer or was it a mistake?
