Need to be show how to solve step by step. And find a least common multiple
Firlakuza [10]
A cheap way to go about it is, use the LCD and multiply both sides by it.

now, notice the denominators, x, 4, 4x, clearly the LCD is 4x, so let's multiply both sides by that, to do away with the denominators,

\bf \cfrac{5}{x}+\cfrac{3}{4}=\cfrac{8}{4x}\implies \boxed{4x}\left(  \cfrac{5}{x}+\cfrac{3}{4} \right)=\boxed{4x}\cdot \cfrac{8}{4x}\implies 20+3x=8
\\\\\\
3x=-12\implies x=\cfrac{-12}{3}\implies x=-4

A family eats dinner and the cost of the meal totals $50, before tax. The tax rate is 10% They also want to tip 20% of the bill,
Butoxors [25]

Answer:

66.00

Step-by-step explanation:

Convert 10% to a decimal by moving the point from 10. to 0.10 (back two places) and multiply it by 50 which gives you $5, which equals the tax they payed. Now they want to tip 20% of the entire bill including tax, so convert 20% to a decimal 20. to 0.20. Now multiply .20 * 55(55 is the $50 payed in meals and the $5 payed in taxes added) And you get $11 for the tip. Add 55 +11 and there's your answer

Guests at a pizza party are seated at three tables. The small table has 5 seats and 2 pizzas. The medium table has 7 seats and 3
bagirrra123 [75]

Answer:

the 5 seated table with the 2 pizzas got more each.

Step-by-step explanation:

\frac{5}{2} = 2\frac{1}{y2} pieces each

\frac{7}{3} = 2\frac{1}{3} pieces each

\frac{12}{5} = 2\frac{2}{5} pieces each

Now change the fractions s that they all have a common denominator.

2\frac{1}{2} = 2\frac{15}{30}

2\frac{1}{3} = 2\frac{10}{30}

2\frac{2}{5} = 2\frac{15}{30}

Thus meaning that the 5 seated table with the 2 pizzas got more each.
