Answer:

hello :

y = –2x – 1....(1)

y = 3x–1.....(2)

by (1) and (2) : 3x-1 = -2x-1

5x =0

x =0 ....(the x-coordinates of the solutions)

when camping alone , mr adam uses all of the water in 12 days, then when mrs adams and mr adams camp together they use all of th

professor190 [17]

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.

Given the diagram below find x, and the measure of

Sophie [7]

Answer:

8, 40 , 50

Step-by-step explanation:

the measure of A is 90°

so 5x + 7x - 6 = 90

now.. to find the x

5x + 7x - 6 = 90

5x + 7x = 90 + 6

12x = 96

x = 96/12

x = 8

so the measure of angle A1 is (5*8) = 40

the measure of angle A2 is (7*8-6) = 50

finaly the angle A is (50+40) = 90

If y varies inversely as x and y=3 when x=14, find x when y=6

alukav5142 [94]

X=7 What you can do is look at the first two values given, and make them x1 and y1. Then your next value here is y2.

So x1 is 14, and y1 is 3. y2 becomes 6. X2 is unknown.

Then make the formula: x1/y2 is equal to x2/y1
(You are setting two fractions equal to each other)

That makes 14/6=X/3. When we cross multiply, we find that x=7.
