In an equation or inequality, you want to get the variable.

1 answer:

7 0

What you want to do is get the variable x on the left side by itself (just like you would if this were an equation). Be sure to perform the same operations on both sides of the inequality until x is all by itself on the left side.

Log4(2-x)=log4(-5x-18)

saveliy_v [14]

$\log_4 (2-x) = \log_4 (-5x-18)\\\\\implies 2-x = -5x -18\\\\\implies 5x -x = -18-2\\\\\implies 4x = -20\\\\\implies x = -\dfrac {20}4\\\\\implies x = -5$

What is the probability of pulling out a red marble then a blue marble?

statuscvo [17]

Answer:

Step-by-step explanation:

Total marble = 8+5+4 = 19

n(Y) = 8, n(B) = 4 and n(R) = 5

Prob(R) = 5/17

Prob(B) = 4/16 {one marble is pulled out already}

Prob(R and B) = 5/17 × 4/16

= 5/17 × 1/4

= 5/68

The ratio of an angle to its supplement is 3:5. Find the angle and it's supplement.

schepotkina [342]

Call one of the angles = x

The other one is 180 - x

They are in the ratio of 3 to 5

Equation

3/5 = x / (180 - x)

Solve

3/5 = x / (180 - x) Cross Multiply

3*(180 - x) = 5x

540 - 3x = 5x Add 3x to both sixes

540 = 5x + 3x

540 = 8x

Divide both sides by 8

540 / 8 = x

x = 67.5

One angle is 67.5

The supplement is 180 - 67.5 = 112.5

Check

67.5/112.5 = 0.6 which is the same thing as 3/5
