The ratio of two numbers is 8 to 5. The difference in two numbers is 24. What are the numbers?

1 answer:

8 0

Let, the numbers are: 8x, 5x
It is given that, 8x - 5x = 24
3x = 24
x = 24/3
x = 8

So, 8x = 8(8) = 64
also, 5x = 5(8) = 40

In short, Numbers would be 40 and 64

Hope this helps!

The linear scale factor of two shapes is 3:4. If the area of the smallest shape is 72^2 what is the area of the big shape?

Lorico [155]

Answer:

$\boxed{6912 units^2}$

Step-by-step explanation:

<em>Hey there!</em>

Well using the given ratio,

3:4

And the area of the small shape we need to do,

72*72 = 5184

Now we can make the following fractions,

$\frac{3}{4}$ = $\frac{5184}{x}$

Now we can solve,

3*x = 3x

4 * 5184 = 20736

3x = 20736

20736 / 3

x = 6912

So the area of the bigger shape is 6912 units^2

<em>Hope this helps :)</em>

What is the x-intercept for the following linear equation:

Alexandra [31]

The "x-intercept" occurs when y=0, because it is at this point that the equation touches the x axis. So if you plug in y=0 into the equation you can solve for the x coordinate.

4x-2(0)-8=0

4x-8=0

4x=8

x=2

So the x-intercept is the point (2,0)
