Answer:

x=-12

Step-by-step explanation:

\frac{1}{3}x - 4 = \frac{3}{4} x+ 1

To remove the denominator we take LCD

LCD of 3  and 4  is 12

In the second step we multiply the whole equation by 12 not only the fractions

12*\frac{1}{3}x - 4*12= \frac{3}{4} x*12+ 1*12

Now the denominator gets removed

1/3 * 12 = 4 , also 3/4 times 12 = 3*3 = 9

4x - 48 = 9x + 12

Subtract 9x on both sides

-5x - 48 = 12

Now add 48 on both sides

-5 x = 60

Divide both sides by -5

so x= -12

The value of x= -12

The equations x + 5 y = 10, 3 x minus y = 1, x minus 5 y = 10, and 3 x + y = 1 are shown on the graph below. On a coordinate pla
natita [175]

Answer:

The question is missing, so I will answer all the solution for each possible system of two equations.

Step-by-step explanation:

The equations

x + 5 y = 10 (red)

3 x - y = 1 (blue)

x - 5 y = 10 (green)

3 x + y = 1 (purple)

are shown in the picture atatched. The intersection between two lines is the solution of their system.

<u>system:</u>

x + 5 y = 10 (red)

3 x - y = 1 (blue)

<u>solution</u>: (0.938, 1.813)

<u>system</u>:

x + 5 y = 10 (red)

x - 5 y = 10 (green)

<u>solution</u>: (10, 0)

<u>system</u>:

x + 5 y = 10 (red)

3 x + y = 1 (purple)

<u>solution</u>: (-0.357, 2.071)

<u>system</u>:

3 x - y = 1 (blue)

x - 5 y = 10 (green)

<u>solution</u>: (-0.357, -2.071)

<u>system</u>:

3 x - y = 1 (blue)

3 x + y = 1 (purple)

<u>solution</u>: (0.333, 0)

<u>system</u>:

x - 5 y = 10 (green)

3 x + y = 1 (purple)

<u>solution</u>: (0.938, -1.813)

P(B | A) = probability of B given A

P(B | A) = P(B and A) / P(A)

thus

P(new oil filter | oil change) = P(both) / P(oil change)

= 0.14 / 0.25

(b) = 0.14 / 0.4
