<h3>Linear expression represents the missing length</h3>

<em><u>Solution:</u></em>

The perimeter of the triangle shown is represented by the  expression 10x - 1

The lengths of two sides are given: 3x + 1 and 5x - 2

We have to find the length of third side

We know that,

perimeter of the triangle = sum of length of all three sides

10x - 1 = 3x + 1 + 5x - 2 + third side

10x - 1 = 8x - 1 + third side

third side = 10x - 1 - 8x + 1

third side =2x

2x has variable x and its power is 1

Linear expression is an algebraic expression where the power of variable is equals to 1

Thus linear expression represents the missing length

Cynthia is 6 times as old as Rebecca. In 6 years, Cynthia will be only 3 times as old as Rebecca. How old is Rebecca now?
fiasKO [112]

Answer:

16 y.o

Step-by-step explanation:

say rebecca = x

therefore, cynthia = 6x

when rebecca ages 6 years (x+6), cynthia will be 3(x+6) years old

since cynthia's original age + 6 will be equal to the new expression of her age after 6 years

3x + 18 = 6x + 6

18 = 3x + 6

3x = 12

x = 4

as cynthia = x + 6 (NOTE: AT THE BEGINNING) her original age was 10.

however after 6 years she's 16

What is the slope of the line in this graph?
den301095 [7]

Answer:

The slope is 5/6

Step-by-step explanation:

To calculate the slope here, there are two ways.

Count the rise over run with the boxes

Or

Find Any 2 points and use y2-y1/x2-x1 to find slope

Both ways work.

For this graph Since it looks pretty basic, I‘ll use the rise over run technique

Now we start from the origin side that is where one point is and just rise vertically until I reach a point and when I do, just run that many steps.

So I reached till 5 and ran to 6 which is a  point on the coordinate graph

So to put it in slope form, it’s rise over run

Heres a easy way to remember it

lets say you wake up, you have to rise first and then run

You can’t run and then rise, that makes no sense

So here its rise 5 and run 6

so 5/6 is the slope

Which expression is equivalent to -3x + 24
zalisa [80]

Answer:

-1x + 8

Step-by-step explanation:

Since you did not give any multiple choice options, here is a problem that is equivalent, because I divided the whole problem by 3, making it exactly equal to the other problem in size.

If two fair dice are rolled, what is the probability that the total showing is either even or less than five?
snow_tiger [21]

The Probability that the total showing is either even or less than five = 5/6

<h3>What is Probability?</h3>

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. The probability of an event is a number between 0 and 1, where, broadly speaking, 0 represents the event's impossibility and 1 implies certainty.

<h3>According to the given data:</h3>

The example space for rolling two dice is:

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

36 events total.

Events that have a sum that is even or less than Five .

Total instances when the aggregate is even or less than Five equals 30.

P(sum is even or less than 5)

= (Total no of favorable event)/(Total no of event)

= 30/36

=5/6

probability that the total showing is either even or less than five = 5/6
