What is the sum of a-1/abc^3 + 3-b/abc^3

Lyrx [107]

The answer is $\frac{a-b+2}{abc^{3} }$

The expression is $\frac{a-1}{abc^{3} } + \frac{3-b}{abc^{3} }$

Since $\frac{a}{x} + \frac{b}{x} = \frac{a+b}{x}$ , then:

$\frac{a-1}{abc^{3} } + \frac{3-b}{abc^{3} } = \frac{a-1+3-b}{abc^{3} }= \frac{a-b-1+3}{abc^{3} }=\frac{a-b+2}{abc^{3} }$

Solve 20x + 12 ≥ 14x + 30

Rashid [163]

Subtract 14x from both sides to get

$20x-14x+12 \geq 30$

Subtract 12 from both sides to get

$20x-14x \geq 30-12$

Now we have moved all terms involving x on one side, and all constant terms on the other. We can simplift both sides, i.e. sum like terms, to get

$6x \geq 18$

Now we have to divide both sides by 6. When dealing with inequality you have to be careful about dividing both sides by the same constant: if the constant is negative, the inequality side switches (i.e. $\geq \leftrightarrow \leq$ ). But this is not the case since 6 is positive, so we mantain the inequality sign:

on the other. We can simplift both sides, i.e. sum like terms, to get

$\cfrac{6x}{6} \geq \cfrac{18}{6}$

Evaluate left and right hand side:

$x \geq 3$
