Answer:

y=17x-187 where x>11

Step-by-step explanation:

Niall gets $34 for 2 hours.

So, he gets 34/2=17 dollars per hour.

Now he owes $187 to his cousin.

Let the number of hours he works be = x

Let the money left with him after paying his cousin be = y

So, the equation forms:

y=17x-187

Rather we can say it is :

y=17x-187 where x>11

If we want to know how many hours are needed to pay the debt, we can consider y = 0

17x-187=0

17x=187

x=187/17

So, x = 11 hours

He needs 11 hours of work to pay back his cousin and after that all his earnings is 'y'. When x>11 then 'y' will have some money left.

Several people form groups with four people in each group.Write an expression for the number of groups formed by p people. How m
Iteru [2.4K]

Answer:

Number of groups formed by '<em>p</em>' people = \frac{p}{4}

Number of groups formed with 28 people = 7

Step-by-step explanation:

We are given that, there are 4 people in 1 group.

Now, at first we have to find the number of groups formed by '<em>p'</em><em> </em>people.

Here, we will use the unitary method.

Number of group formed with 4 people = 1

So, number of group formed with 1 person = \frac{1}{4}

∴ number of groups formed with '<em>p'</em> people = \frac{1}{4}\times\;p=\frac{p}{4}

So, the required expression for the number of groups formed by '<em>p</em>' people is \frac{p}{4}

Now, secondly we have to find the number of groups formed by 28 people.

As, we know that number of groups formed with '<em>p</em>' people = \frac{p}{4}

Now, putting '<em>p'</em> = 28 in the expression obtained above, we get

number of groups formed by 28 people = \frac{28}{4} =7

So, there are 7 groups formed with 28 people.

-f(3f-7)=0 solve equation<br>​
kenny6666 [7]

Answer:

F=0 or (7/3)

Step-by-step explanation:

When F is 0, the equation reads -0(3(0)-7)=0. The outside 0 will multiply by everything and make it equal 0. When F is 7/3, the inside of the parenthesis read 3(7/3)-7. This equals 7-7. It'll end up being (7/3)0, which equals 0.
