The answer is the sixth grade class.

In order to find the answer, you have to divide each grade's total by the number of hours it took them to make that money, which will give you the amount each class makes per hour. 

$170 / 55 = $3.09
$112 / 44 = $2.54
$192 / 66 = $2.91

Write y=-(3/5)x-2 in standard form using integers <br> please thank you

Y= -3/5x - 2       Add -3/5x to both sides 
3/5x +y= -2        Multiply both sides by 5 because 5 is the denominator.
                        By multiplying by 5 you can cancel out and make it a real number. 
5(3/5x +y) = -2(5) 
 
   3x + 5y= -10  is the answer.

Osama starts with a population of 1,000 amoebas that increases 30% in size every hour for a number of hours, h. The expression 1
Blizzard [7]

Answer: The correct option is A, itis the product of the initial population and the growth factor after h hours.

Explanation:

From the given information,

Initial population = 1000

Increasing rate or growth rate = 30% every hour.

No of population increase in every hour is,

1000\times \frac{30}{100} =1000\times 0.3

Total population after h hours is,

1000(1+0.3)^h

It is in the form of,

P(t)=P_0(t)(1+r)^t

Where P_0(t) is the initial population, r is increasing rate, t is time and [tex(1+r)^t[/tex]  is the growth factor after time t.

In the above equation 1000 is the initial population and (1+0.3)^h is the growth factor after h hours. So the equation is product of of the initial population and the growth factor after h hours.

Therefore, the correct option is A, itis the product of the initial population and the growth factor after h hours.

Step-by-step explanation:

let the number be x.

2x+5= -5 ====> equation

2x= -5-5. (shifted the +5 to the other side)

2x= -10

x= -10/2 ( shifted 2 on the other side as it was multiplying with x)

x= -5
