Lerok [7]

So basically it's just a simple division equation (kind of):
600/3000
We can simplify this so the denominator is 100
20/100
So she saved 20% of her money in the month of January.

You and your friend leave your houses at the same time to meet at a restaurant. The distance (in miles) your friend is from the

salantis [7]

Answer:

Thus, the linear equation to represents your distance from the restaurant is given as:

$y=-60x+90$

Step-by-step explanation:

Given:

The distance (in miles) your friend is from the restaurant is given by:

$y=-50x+75$

where $x$ represents the number of hours since your friend left home.

You live 90 miles from the restaurant and arrive at the same time as your friend.

To write a linear equation that represents your distance from the restaurant.

Solution:

From the given linear equation for your friend, we can say that the distance between your friend keeps decreasing as he approaches near the restaurant. The distance will be = 0 when your friend reaches the restaurant.

Thus, we can plugin y=0 to find $x$ i.e.the time in hours taken by your frient to reach the restaurant.

$0=-50x+75$

Adding $50x$ both sides.

$0+50x=-50x+50x+75$

$50x=75$

Dividing both sides by 50.

$\frac{50x}{50}=\frac{75}{50}$

$x=1.5\ hours$

Your friend takes 1.5 hours to reach the restaurant

It is given that you and your friend start at same time and reach the restaurant at the same time. And you are 90 miles from the restaurant initially.

The linear function representing your distance from the restaurant can be given as:

$y=-mx+90$
