Answer:

$9\frac{3}{2}$ smallest

$27\frac{1}{3}$

$125\frac{2}{3}$ largest

Step-by-step explanation:

First change the mixed numbers into an improper fractions.

$9\frac{3}{2}$ = $\frac{21}{2}$ 9 x 2 = 18 + 3 = 21

$27\frac{1}{3}$ = $\frac{82}{3}$ 27 x 3 = 81 + 1 = 82

$125\frac{2}{3}$ = $\frac{377}{3}$ 125 x 3 = 375 + 2 = 377

Find the least common denominator.

2 and 3 have 6

$\frac{21}{2}$ = $\frac{63}{6}$ smallest

$\frac{82}{3}$ = $\frac{164}{6}$ medium

$\frac{377}{3}$ = $\frac{754}{6}$ largest

Tony was Challenged to a half-court shooting competition. For every half-court shot that he makes, he will earn 20 points. For e

Mkey [24]

Answer:

Tony make 4 half-court shots and misses 16 half-court shots.

Step-by-step explanation:

Given:

Points earned for every successful, half-court shots = $20$

Points deducted for missing the shots = $5$ or $-5$

Total number of shots in the game = $20$

Final points earned by Tony = $0$

According to the question:

Let the number of successful half-court shot be $x$

And the number of shots missed be $20-x$

So,

In terms of points we can re-write it as:

⇒ $20(x)-5(20-x) =0$

⇒ $20x-100+5x=0$

⇒ $25x-100=0$

⇒ $25x-100+100=100$

⇒ $25x=100$

⇒ $\frac{25x}{25} =\frac{100}{25}$

⇒ $x=\frac{100}{25}$

⇒ $x=4$

Tony make 'x' shots that is 4 and the number of shot he missed is (20-x) =(20-4)=16

What type of solution does 11x - 2 + 15 = 8 + 7 + 9x have?

sergiy2304 [10]

Given equation is : 11x - 2 + 15 = 8 + 7 + 9x

Solving this by grouping like terms on one side.

$11x-9x=8+7-15+2$

$2x=17-15$

$2x=2$

$x=1$

Hence, this equation has one solution.

The sales tax rate in Jan's town is 7.5%. If she buys 3 lamps for $23.59 each and a sofa for $769.99, how much sales tax does sh

Lilit [14]

The total price of all 3 lamps without the sales tax is $70.77
add the price of the sofa
$70.77+$769.99= $840.76
the tax is being added on to the total price
so multiply the $840.76 by .075 which is the sales tax
the total sales tax she owes is $63.05
