Is 8/5 proportional to 24/15 ?
DiKsa [7]

Hey there!

The answer to your question is, yes, it is

Given:

\frac{8}{5} and \frac{24}{15}

To see if they are equal, we can use cross products (see below for information about this, if you don't know what it is). Let us assume they are equal. This would mean that:

8*15=24*5

Let's solve it and see if it is true:

8*15=24*5

120=120

Therefore, they <em>are </em>proportional.

<u>Cross products</u>

WORD DEFINITION:

Given two fractions, you can take the numerator of the first fraction multiplied by the denominator of the second fraction and it should equal the denominator of the first fraction multiplied by the numerator of the second fraction.

ALGEBRAIC DEFINITION:

Given two fractions, \frac{a}{b} and \frac{c}{d}, a*d <em>should </em>equal to b*c

Hope it helps, and have a terrificly amazing day!

Tara has two standard, six-sided dice. If she rolls them 36 times, how many times should she expect a sum less than 5 to show up
andreyandreev [35.5K]
There are six sides on each die. For each possible score on Die 1, there are six possible scores on Die 2. So the number of possible combinations is 6*6 = 36. 
<span>It follows that if the dice are thrown 36 times, you would expect each combination to come up once. </span>

<span>We therefore simply need to know how many combinations add up to less than 5. (I've interpreted this as not including a total of 5 itself). </span>
<span>These combinations are: 1 and 1, 2 and 1, 1 and 2, 2 and 2, 3 and 1, and 1 and 3 ---> six combinations out of 36. </span>

<span>So you'd expect a sum less than 5 six times. </span>

Which equation is not equivalent to 2x + 14 = 4x - 6
LuckyWell [14K]
2x + 14 = 4x - 6
14 = 2x - 6
20 = 2x
10 = x

a) 14 + 6 = 2x
20 = 2x
10 = x

b) -2x = 20
x = -10

c) 2x - 4x = -20
-2x = -20
x = 10

d) x = 10

b is the only one that doesn’t equal 10.

Find the midpoint of AB if A is (-3,-3) and B is (6,6)?
blondinia [14]
(x, y)

When you are asked for the midpoint, just find the average for both the x and y components:

So the midpoint for A(-3, -3) and B(6, 6) 

The xs components are  -3, and 6,  Average = (-3 + 6)/2 = 3/2 = 1.5

The ys components are  -3, and 6,  Average = (-3 + 6)/2 = 3/2 = 1.5

So the midpoint is (1.5, 1.5)

I hope this helps.
