Solve for x x-xy=z Hint: reverse distribution to get x alone

Mathematics

<h3>Answer:  x = z/(1-y)</h3>

Work Shown:

x - xy = z

x*1 - x*y = z

x*(1 - y) = z .... distributive rule in reverse

x = z/(1-y) ..... divide both sides by (1-y)

The distributive rule is a*(b+c) = a*b+a*c. You can also say a*(b-c) = a*b-a*c. In this case, we factored out the common factor x.

North America burned 4.5 x 1016 btu of petroleum in 1998. At this rate, how many BTU's will be burned in 9 year?
nikklg [1K]
Hello. Sonny solving this equation, multiplying 4.5 by 1016 will give us 4,572 BTU's a year. However, we are looking for the amount looking for the amount that will burn in 9 years. When you multiply 4,572 by 9, you get 41,148. 41,148 BTU's will be burned in 9 years.

I WILL AWARD BRAINLIEST!! PLEASE HELP!!
lara31 [8.8K]

Answer:

A(...; 7)

x =-1/5

B(8; ...)

y = 48

The slope is 5

Step-by-step explanation:

y−5x=8

A(...; 7)

We know that y=7, we need to find x

7 - 5x = 8

Subtract 7 from each side

7-7 -5x = 8-7

-5x =1

Divide by -5

-5x/-5 = 1/-5

x =-1/5

B(8; ...)

We know x = 8 we need to find y

y−5x=8

y - 5(8) = 8

y - 40 =8

Add 40 to each side

y-40+40 = 8+40

y = 48

Now we need to find the slope

y - 5x =8

Add 5x to each side

y -5x+5x = 5x+8

y = 5x+8

This is in the form y = mx+b  where m is the slope

The slope is 5

Is this greater than, less than, or equal to
jeka57 [31]
When doing something like this you want to make sure both sides are the same, so turn 7/4 into a percent. 7/4 equals 175, therefore they’re equal to each other.
