3*(x-1)/4 + 1 &lt; x-2/3
ICE Princess25 [194]

Answer:   x>11/3

Step-by-step explanation:

Let's solve your inequality step-by-step.

Step 1: Simplify both sides of the inequality.

Step 2: Subtract x from both sides.

Step 3: Subtract 1/4 from both sides.

Step 4: Multiply both sides by 4/(-1).

6x^-2 -7x^-1 +1=0<br> Solve by making appropriate substitutions
tatyana61 [14]
Let y=x^{-1}, so that y^2=x^{-2}. Then

6x^{-2}-7x^{-1}+1=0\iff6y^2-7y+1=0\implies (6y-1)(y-1)=0

which has two solutions, y=\dfrac16 and y=1. So the solutions in terms of x would be

x^{-1}=\dfrac16\implies x=6
x^{-1}=1\implies x=1

Could anyone give me the answer to this question?
love history [14]

Answer:

36

Step-by-step explanation:

\angle AOC is made up of s + r, and since r is \frac{3}{5} of \angle AOC we know r must be the remaining \frac{2}{5} of \angle AOC.

We can solve for \angle AOC by using this equation:

\frac{2}{5}\angle AOC = 24\\(\frac{2}{5}\angle AOC)\frac{5}{2} = (24)\frac{5}{2}\\ \boxed{\angle AOC = 60}

1. 2 fifths of  \angle AOC is 24

2. multiply both sides by \frac{5}{2} to isolate \angle AOC

3. \angle AOC is 60°

We can now solve for r

r = \frac{3}{5}\angle AOC\\r = \frac{3}{5}(60)\\\boxed{r = 36}

1. the equation the problem gave us

2. substitute \angle AOC for 60 (we solved for it before)

3. r is 36°
