Roberto is having his house painted. The job takes three days, and he pays the painter the same hourly rate
Tom [10]

Answer:

\$60\ per\ hour

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x -----> the number of hours worked

y ----> the amount paid in dollars

In this problem we have a proportional variation, between two variables, x, and y

<em>Find out the constant of proportionality k</em>

For (5,300) -----> k=y/x ----> k=300/5=60\ \$/h

For (4,240) -----> k=y/x ----> k=240/4=60\ \$/h

For (6,360) -----> k=y/x ----> k=360/6=60\ \$/h

The constant k is

k=60\ \$/h

The equation is equal to

y=60x

The unit rate of change of dollars with respect to time is equal to the constant of proportionality or slope of the linear equation

therefore

\$60\ per\ hour

If aſc and a +b = C, prove that a|b.
mars1129 [50]

Answer with Step-by-step explanation:

Since we have given that

a + b = c

and a|c

i.e. a divides c.

We need to prove that a|b.

⇒ a = mb for some integer m

Since a|c,

So, mathematically, it is expressed as

c= ka

Now, we put the above value in a + b = c.

So, it becomes,

a+b=c\\\\a+b=ka\\\\b=ka-a\\\\b=a(k-1)\\\\\implies a|b

a=mb, here, m = k-1

Hence, proved.
