Subtract all his expenses from the amount he spent to operate, and what's left is the amount he spent on gas, which is $596.  If you then divide the number of miles he drove by the amount he spent, you get .08349.  But that is expressed in terms of dollars.  If it's in terms of cents, you have to multiply that number by 100 to get 8.35 cents, rounded to the nearest hundredth.

To express a number in one unit as an equivalent value of another unit
ddd [48]
A conversion factor is a number used to change one set of units to another, by multiplying or dividing. When a conversion is necessary, the appropriate conversion factor to an equal value must be used. For example, to convert inches to feet, the appropriate conversion value is 12 inches equal 1 foot.

When you are given three side lengths for a triangle, how do you know which length to substitute for a, b, or c in the Pythagore
Romashka [77]

Answer:

When Sum of square of two Sides is equal to square of third side of triangle.

Step-by-step explanation:

Given:

Three side length of triangle are given we need find the which value to substitute for a, b, c in Pythagoras theorem.

First we will find the squares of all length, then we will check which two square of side are equal to square of third side as per Pythagoras theorem.

Hence the two side would according be a and b and third side will become c.

For example if length of triangle  is given as 6 cm, 8 cm and 10 cm.

We will first take square of all

6^2=36\\8^2=64\\10^2=100

Now we can see that

36+64=100\\6^2+8^2=10^2

Now by Pythagoras theorem.

a^2+b^2=c^2

Hence we can say a = 6 cm, b = 8 cm, c= 10 cm

Answer:

y= -6/5x -3

Step-by-step explanation:

So for now lets bring it into mx + b format

Subtract 6x from both sides to isolate y which is also called subtraction property of equality.

so 5y = -6x -15

Now you divide both sides by 5 which is called division property of equality.

You now have y = -6/5x - 3

y= -6/5x -3 is the slope intercept form of the standard form equation of 6x + 5y = -15.

Hope this helps!
