We are given with the equation (a-c)/(x-a) = m. In this case, to isolate x, we can use the division, multiplication, addition adn subtraction properties. In this case, Divide the whole equation by m, to give, (a-c)/(x-a)/m = 1. Then multiply by (x-a). Then to isolate x, add a. this results to
x = [(a-c)/m]

If you would like to solve the equation<span> (a - c) / (x - a) = m for x, you can do this using the following steps:

</span><span>(a - c) / (x - a) = m
</span>a - c = m * (x - a)
a - c = mx - ma
mx = a - c + ma
x = (a - c + ma) / m
x = a/m - c/m + a

The correct result would be <span>x = a/m - c/m + a.</span>

Answer:

B) -3 (Sorry if its overwhelming)

Explanation:

First, we have the given information of the weather over a <em>2</em> and <em>1/5</em> <em>span</em>

And we are asked to find the change per hour

We can first start by finding the <em>change</em> for 2 and 1/5 hours:

- Subtract the first amount by the second amount.

= (-6 3/5) - 0

= (-6 3/5) + 0

= -6 3/5

Now that we have the change for <em>2 and 1/5 hours</em> we must find the <em>change</em> per hour:

- Divide the given dividend by the given divisor

= -6 3/5 ÷ 2 1/5

= -3

Hence, the temperature <em>change per hour</em> over a 2 1/5 hour span is -3° per hour

Does anyone know the answer to this problem?

The regression equation is y = 16.585x - 639.769 and the linear correlation coefficient indicates a strong linear relationship

<h3>How to determine the regression equation?</h3>

To do this, we make use of a statistical calculator;

Using the statistical calculator, we have the following summary:

Sum of X = 554
Sum of Y = 4070
Mean X = 69.25
Mean Y = 508.75
Sum of squares (SSX) = 725.5
Sum of products (SP) = 12032.5
Correlation coefficient, r = 0.9768

The regression equation is

ŷ = bx + a

Where:

b = SP/SSX = 12032.5/725.5 = 16.58511

a = MY - bMX = 508.75 - (16.59*69.25) = -639.76912

Hence, the regression equation is y = 16.585x - 639.769

<h3>The number of cans sold at 90 degrees F</h3>

This means that"

x = 90

So, we have:

y = 16.585 * 90 - 639.769

Evaluate

y = 852.881

Approximate

y = 853

Hence, 853 cans were sold at 90 degrees F

<h3>The linear correlation coefficient</h3>

In (a), we have:

r = 0.9768

This means that the linear correlation coefficient is 0.9768

<h3>The conclusion</h3>

We have:

r = 0.9768

The above value is closer to 1 because

|r| > 0.9

i.e.

0.9768 > 0.9

Hence, the linear correlation coefficient indicates a strong linear relationship

Ok here is a better pic I need help with it

BartSMP [9]

Answer:

Step-by-step explanation:

First,You have to realize that if you multiply the amount of food by something, you multiply the amount of calories. if some piece of food is 100 calories what happens if you eat 2? you get 2 times that number of calories. Same fi you eat half of one of that kind of food. You get half the amount of calories.

Here he makes 1 1/2 (one and a half) times the amount. Now, if this is confusing you just need to realize that multiplying by this is the same as multiplying by 1+1/2. Say, again, a piece of food is 100 calories. Multiplying it by this would look like the following.

100(1+1/2)

100*1 + 100*1/2

100+50

150

So if you ever have a mixed number like this you could split it up into an addition problem and then distribute hat you're multiplying. Another solution is to multiply by the improper fraction, which here is 3/2, so 100*3/2=150 as well. Let me know if you don't get how to get the improper fraction or how to multiply fractions.

Now, super simple, just multiply the calories by that number.

310(1+1/2) = 310(3/2)

310 + 155 = 930/2

465 = 465

Kinda showed how to multiply by fractions, still if you don't get it let me know.
