Hey there!

Both people read a total of 23 books . . .

23 - 5 = 18

18 divided by 2 = 9

This means Nang read 9 books.

9 + 5 = 14 <-------

Simone read 5 more books than Nang. . .

Simone read 14 books.

Cammie can mow 1/2 acre in 25 minutes. If her rate is constant, Cammie says she can mow 1 1/4 acres in one hour. Is Cammie corre

Sergeu [11.5K]

Answer: No, Cammie is not correct. She can mow $1\frac{1}{5}\ acres$ in one hour (See explanation).

Step-by-step explanation:

Convert the mixed number to an impoper fraction:

1. Multiply the whole number part by the denominator of the fraction and add the product to the numerator.

2. The denominator does not change.

Then:

$1\frac{1}{4}=\frac{(1*4)+1}{4}=\frac{5}{4}$

Let be "x" the acres Cammie can mow in one hour.

You know that she can mow $\frac{1}{2}\ acre$ in 25 minutes, then you can set up the following proportion (Remember that 1 hour has 60 minutes):

$\frac{\frac{1}{2}}{25}=\frac{x}{60}$

Solving for "x", you get:

$\frac{\frac{1}{2}}{25}=\frac{x}{60}\\\\(60)(\frac{1}{50})=x\\\\x=\frac{6}{5}$

Convert from improper fraction to mixed number:

1. When you divide 6 by 5, the quotient is 1. This will be the whole number part.

2. The remainder is 1. This will be the numerator.

3. The denominator does not change.

Then:

$x=1\frac{1}{5}$

Therefore, she can mow $1\frac{1}{5}\ acres$ in one hour.

Which number should each side of the equation 4/5x=8 be multiplied by to produce he equivalent equation of x=10?

gulaghasi [49]

<< Add $.\frac{-4}{5}$ to the left and right of the equation, multiple and make ''opposite multiplation'' to find x.

A) $\frac{4}{5x}. \frac{-4}{5} = 8. \frac{-4}{5} 
$
$\frac{16}{25x} = \frac{-32}{5}$
25x.(-32)= (-16).5
-800x= -80

**to leave x alone and positive, you must divide to -800.
$x= \frac{-80}{-800}$
$x= \frac{1}{10}$
= INCORRECT

B) $\frac{4}{5x} . \frac{1}{5} = 8. \frac{1}{5} 
$
$\frac{4}{25x} = \frac{8}{5}$
$25x.8= 4.5$
$200x=20
$
$x= \frac{20}{200} = \frac{1}{10}$

C) $\frac{4}{5x} . \frac{5}{4}= \frac{8.5}{4}$
$\frac{1}{x} = \frac{40}{4}$
$\frac{1}{x} =10$
10x=1
$x= \frac{1}{10}$

D) $\frac{4.5}{5x} = 8.5$
$\frac{4}{x} = 40$
40x= 4
x= $\frac{4}{40}$ = 1/10

I think there is a problem with the options :D

Stephanie grew a total of 70 pounds of tomatoes to sell. She plans to sell the tomatoes for $3.50 per pound. The equation below

Alexxandr [17]

Answer:

If Stephanie sold the 70 pounds of tomatoes, her profit would be 135 dollars.

Step-by-step explanation:

You know that the equation f(x) = 3.50*x - 110 represents the profit in dollars Stephanie will earn by selling x pounds of the tomatoes.

If Stephanie sold the 70 pounds of tomatoes, you want to know what the profit would be. So to calculate the profit you simply replace in f (x), the x pounds of tomatoes by 70.

f(70)=3.50*70 - 110

Solving:

f(70)= 245 - 110

f(70)= 135

If Stephanie sold the 70 pounds of tomatoes, her profit would be 135 dollars.
