10. The sum of two numbers is 102. One number is three less than twice the other.
What are the two numbers?

Answers

Answer 1

Answer:

(2n -3) + n = 102

2n - 3 + n = 102

3n - 3 = 102

3n = 105

n = 35 (the first number)

SO...

The other number is (2 x 35) - 3 =

                                           70 - 3 = 67 (the second number)

The numbers are 35 and 67.

35 + 67 = 102 CHECK!

The accompanying diagram shows two triangles. Which proportion could be used to solve for x ?

Answers

Answer:
A) 32/x=12/15

Explanation:
When we compare 32/x, we’re looking the ratio between the two side lengths on the first triangle. When we compare 12/15, we’re looking at the ratio between the two side lengths on the second triangle. These ratios must be equal to each other since the two triangles are similar, and we can use this to solve for x.

Find the 9th term of the geometric sequence 9, -27, 81...

Answers

Answer:

a9= 59049

Step-by-step explanation:

Find the r.

R= 81/-27

R= -3

a1= 9

a2= -27

a3= 81

a4= 81*-3= -243

a5= -243*-3= 729

a6= 729*-3= -2187

a7= -2187*-3= 6561

a8= 6561*-3= -19683

a9= -19683*-3= 59049

j – 18 = 43 what's the answer guys

Answers

Answer:

61

Step-by-step explanation:

We know from the equation 43 is 18 less then j. Therefore, if we add 18 to 43, we will get the value of j.

43 + 18 = 61

So first you add 43 and 18 cause the original number is that total - 18 and you get 61

What is the y=mx+b of the equation 3x−2y=12

Answers

Answer:

y=3/2x-6

Step-by-step explanation:

To find the y=mx+b you need to move the y on one side while moving the others on the other side

First, move the 3x to the other side by subtracting by 3x on both sides:

-2y=-3x+12

Divide by -2 on both sides:

y=3/2x-6

Answer:

y=3/2x-6

Step-by-step explanation:

3x-2y=12

isolate the y:

-2y=-3x+12

get rid of the coefficient in front of y by dividing by -2

y=-3/-2x+12/-2

y=3/2x-6

solve for the missing side: simplify the radical ​

Answers

Answer:

[tex]x=8\sqrt{5}[/tex]

Step-by-step explanation:

I will assume the following:

You know how to use  the quadratic formulaYou know how to simplify radicalsYou know how to use the pythagorean theorem.

The challenge of this exercise comes from using the pythagorean theorem and setting up a few equations.

Given that we have a segment 36 units long and another segment that is 16, it is trivial to get the other segment, 20. Additionally, there are two sides that I want to name so that way I can make a couple of substitutions. I will call these side a and side b. (see attachment 1)

Now comes with setting up three equations. I will start with the two smaller triangles, using side a and side b. See attachments 2 and 3.

Now with the big triangle. I will set up one last equation. See attachment 4.

Given what we know about attachment 2 and 3, we can make two substitutions. See attachment 5. I assume you know how to do the rest and arrive at your only real solution.
