Area:volume = area/volume

22:6 = 22/6

We now reduce the fraction by dividing each by 2

That will be: 11/3

The ratio is 11:3

The price of 10 citrons and 7 fragrant wood apples is 55 units. The price of 7 citrons and 10 fragrant wood apples is 64 units.

a_sh-v [17]

Price of one citron = 5 units

Price of one fragrant = 5/7 units = 0.71 units

Further explanation:

Let x be the price of one citron and

y be the price of one fragrant

Then according to given statement

10x+7y = 55 Eqn 1

7x+10y = 64 Eqn 2

Multiplying equation 1 by 7

$7(10x+7y) = 7(55)\\70x+49y=385$

This will be equation 3.

Multiplying equation 2 by 10

$10(7x+10y) = 10(64)\\70x+100y=640$

This will be equation 4.

Subtracting equation 3 from equation 4

$70x+100y - (70x+49y) = 640-385\\70x+100y-70y-49y = 255\\51y = 255\\\frac{51x}{51} = \frac{255}{51}\\x = 5\\Putting\ x=5\ in\ equation\ 1\\10(5)+7y = 55\\50+7y = 55\\7y = 55-50\\7y = 5\\\frac{7y}{7} =\frac{5}{7}$

So,

Price of one citron = 5 units

Price of one fragrant = 5/7 units = 0.71 units

Hillary earned $17.92 weeding gardens for 3.2 hours she was paid the same hourly rate to mow lawns Hillary mowed lawns for 2.75

Sindrei [870]

Answer:

$15.40

Step-by-step explanation:

At a given hourly rate, the pay is proportional to the hours spent earning it. So, we have ...

pay/hours = $17.92/3.2 = (mowing pay) / 2.75

Multiply by 2.75 to get ...

(mowing pay) = $17.92·(2.75/3.2) = $15.40

Hilary earned $15.40 mowing lawns.
