St. augustine grass can grow at the rate of 4 over 7 centimeter per week. how many weeks will it take the grass to grow 12 over 7 centimeters? explain your answer using words, and show your work using division of fractions.

Given, the rate of growth of St. Augustine grass is cm per week.

We have to find the number of weeks that the grass grow to cm.

Let's take the number of weeks be x.

In 1 week the grass grow = cm

So in x weeks the grass grow = cm

So we can write,

To solve it for x, first we will move 7 to the right side by multiplying it to both sides. We will get,

Now to get we will move 4 to the right side by dividing it to both sides. We will get,

So we have got the required answer.

After 3 weeks the grass grow .

-6 is the correct option from the above given options

1. sometimes

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
