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

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
