Solve the following equation for "y": 3x-4y=20

Answers

Answer 1

Answer:

Step-by-step explanation:

20=3x-4y, add 4y to each side

4y+20=3x, subtract 20 from each side

4y=3x-20, divide each side by 4

y=(3x-20)/4 or if you prefer

y=0.75x-5

When 2 dice are rolled, find the probability of getting a sum greater than 8.

Answers

Answer: 10/36

When a pair of fair dice are rolled , the total possible cases are (6 × 6) = 36. Out of these 36 cases the following 10 cases are favors(giving the sum > 8) for the happening of the event . These 10 cases are (3, 6), (4, 5), (4, 6),(5, 4), (5, 5), (5, 6) , (6, 3), (6, 4), (6, 5), & (6, 6)

Step-by-step explanation:

6×6=36 possible outcomes and only 15 possible outcomes summing 8 or more than 8.

Since there are six possible outcomes, the probability of obtaining any side of the die is 1/6. The probability of rolling a 1 is 1/6, the probability of rolling a 2 is 1/6, and so on.

Find three consecutive numbers whose sum equals
999.​

Answers

Answer:

332, 333, 334

Step-by-step explanation:

First, we acknowledge that the equation that we need to solve will be "x+(x+1)+(x+2)=999" This is because x represents the smallest of three consecutive numbers whose sum is 999. Simplifying this equation will leave us with 3x+3=999 which is simplified further to 3x=996 and again simplified to x=332. X is the smallest number of the three.

1. The sum of two numbers is 64. One of the numbers is 16 more than 3 times the other. Find the
two numbers.

Answers

Answer:

The two numbers are 52 and 12.

Step-by-step explanation:

x+y=64

x=16+3y

Now, substitute the second equation into the first one.

16+3y+y=64

16+4y=64

4y=48

y=12

Substitute 12 into one of the equations in order to find x.

x=16+3(12)

x=16+36

x=52

Answers

Parallelogram is the word that most generally describes such a figure. A square or rectangle, which do, of course have right angles, are special cases of the parallelogram.

I am assuming (perhaps unjustifiably) that when you say “two pairs of parallel sides” you are talking of a figure with no other sides than those four.
There are, of course, many other polygons (hexagons, octagons, decagons, etc) which have two pairs of parallel sides and other sides, any two of which may or may not be parallel.

The attached figure is a parallelogram with one corner chopped off, making it a pentagon. It still has two pairs of parallel sides & no right angles.

Find the length of the midsegment of the trapezoid.

Answers

Answer:

29

Step-by-step explanation:

The Trapezoid Midsegment segment theorem states that the length of the midsegment is half the sum of the length of its two parallel sides. Therefore:

MN = ½(AB + DC)

MN = ½(21 + 37)

MN = ½(58)

MN = 29

The coordinates of point T are (0,5). The midpoint of ST is (2,-2). Find the coordinates of point S.
The other endpoint is
(Type an ordered pair.)

Answers

Answer:

[tex]S = (4,-9)[/tex]

Step-by-step explanation:

Given

[tex]T = (0,5)[/tex]

[tex]Midpoint = (2,-2)[/tex]

Required

Find S

Midpoint is calculated as:

[tex]Midpoint = 0.5(x_1 + x_2,y_1+y_2)[/tex]

So, we have:

[tex](2,-2)= 0.5(0+ x_2,5+y_2)[/tex]

Where x2 and y2 are the coordinates of S

Multiply through by 2

[tex]2 * (2,-2)= 2 * 0.5(0+ x_2,5+y_2)[/tex]

[tex](4,-4)= (0+ x_2,5+y_2)[/tex]

[tex](4,-4)= (x_2,5+y_2)[/tex]

By comparison:

[tex]x_2 = 4[/tex]

[tex]5 + y_2 = -4[/tex]

[tex]y_2 = -4-5[/tex]

[tex]y_2 = -9[/tex]

So:

[tex]S = (4,-9)[/tex]
