Answer:

∠ ABD = 37° , ∠ DBC = 58°

Step-by-step explanation:

∠ ABD + ∠ DBC = ∠ ABC , substitute values

2x + 23 + 9x - 5 = 95 , that is

11x + 18 = 95 ( subtract 18 from both sides )

11x = 77 ( divide both sides by 11 )

x = 7

Then

∠ ABD = 2x + 23 = 2(7) + 23 = 14 + 23 = 37°

∠ DBC = 9x - 5 = 9(7) - 5 = 63 - 5 = 58°

The letters a and b represent nonzero constants solve
ax-b=12.5 for x

Answers

Answer:

x=(12.5+b)/a

Step-by-step explanation:

ax-b=12.5

ax=12.5+b

x=(12.5+b)/a

The solution for the equation ax - b = 12.5 for x is:

x = (12.5 + b) / a

We have,

To solve the equation ax - b = 12.5 for x, follow these steps:

- Add b to both sides of the equation:

ax - b + b = 12.5 + b

This simplifies to:

ax = 12.5 + b

- Divide both sides of the equation by "a":

(ax) / a = (12.5 + b) / a

Simplify:

x = (12.5 + b) / a

Thus,

The solution for the equation ax - b = 12.5 for x is:

x = (12.5 + b) / a

Step-by-step explanation:

The number after the decimal is the tenths place. And the second number after the decimal is in the hundredths place. And so on...

So .98 would be in the hundredths place making it 98/100.

If you want to simplify it even more, you would make it 49/50.

Rachel’s free-throw average for basketball is 60%. How many times do you think she will make a free-throw in her next 50 tries?

Answers

Answer:

Rachel will make 30 free-throws!

Step-by-step explanation:

Hello!

I came up with this solution with some easy mental math! If you weren't aware, 60% of 50 is a whole number! Meaning that 60% of 50 is 30. You could even double 50 to make it 100, everyone knows that dealing with percentages with the number 100 make them a whole lot easier!

Back to what I was saying, if you used 100, you would also have to take 60% of 100, which is 60. And then have to divide 60 by 2 because you doubled the 50! Giving you 30 free-throws, which is the correct answer!

Hope this helped! Let me know if you have any further questions! :)

find the distance between each pair of points
-6 -5 2 0

Answers

Hi, I'm happy to help!

To solve this, we need to find the distance in x coordinate values, y coordinate values, then use the Pythagorean Theorem to solve for the distance.

First, let's find the distance in x coordinate values. Our first x coordinate value is -6, and our second is 2. From here, we subtract.

-6-2=-8

Since we have a negative number, we use absolute value, which says how far the number is from 0.

I-8I

8

The distance in x coordinate values is 8.

Next, we find the distance in y coordinate values. our first y coordinate is -5, and our second is 0, now, let's subtract.

-5-0=-5

I-5I

5

The distance in y coordinate values is 5.

From here, we use the Pythagorean Theorem, which states that a²+b²=c².

This has to do with right triangles. Think about drawing a line down to the y coordinate of the other point, then to the x coordinate. Now, drawing a line straight from point to point. Now, you have a right triangle, and we are trying to find c, the direct distance of the line going from point to point. Let's say that our x distance is a, and our y distance is b.

Let's plug in the values:

8²+5²=c²

64+25=c²

89=c²

To find c, we need to find the square root of 89.

√89=c

9.433981132...=c

Since this number goes on forever, we need to round.

Rounding to the nearest thousandth:

9.434

Nearest hundredth:

9.43

Nearest tenth:

9.4

Depending on what the question asks, use one of these values.

To conclude, The distance between the two points is about 9.43 units.

I hope this was helpful, keep learning! :)
