Find x...............

Mathematics
1 answer:
erma4kov [3.2K]3 years ago
6 0

Answer:

x=2

Step-by-step explanation:

1. AB=AC (The triangle is isosceles. This means that at least two of its sides are equal in length. Looking at the triangle in the picture, sides AB and AC look the same, so we will assume that they are equal. Note that as you get more advanced, assuming isn't the best strategy. <em>You should always try to look for hints if you are ever unsure. For example, if there are two angles that are the same measure in a triangle, the two sides that are only touching one of these angles are equal in length. This is called the </em><em>base angles theorem converse</em><em>.)</em>

2. 9x-3=6x+3 (Rewrite sides AB and AC as the values given in the picture. This is called substitution.)

3. 9x=6x+6 (Add 3 to each side)

4. 3x=6 (Subtract 6x from each side)

5. x=2 (Divide each side by 3)

let me know if i did anything wrong, hope this helps!!

What is the answer to 2(3x-4)-5=-7
kozerog [31]

Answer: x = 1

Step-by-step explanation:

1) Reorder the terms:

2(-4 + 3x) + -5 = -7

(-4 * 2 + 3x * 2) + -5 = -7

(-8 + 6x) + -5 = -7

2) Reorder the terms:

-8 + -5 + 6x = -7

3) Combine like terms: -8 + -5 = -13

-13 + 6x = -7

4) Solving

-13 + 6x = -7

5) Solving for variable 'x'.

6) Move all terms containing x to the left, all other terms to the right.

7) Add '13' to each side of the equation.

-13 + 13 + 6x = -7 + 13

8) Combine like terms: -13 + 13 = 0

0 + 6x = -7 + 13

6x = -7 + 13

9) Combine like terms: -7 + 13 = 6

6x = 6

10) Divide each side by '6'.

x = 1

11) Simplifying

x = 1

The cone shown below has a slant height of 15 centimeters and a height of 12 centimeters. What is the radius of the cone.​
Rzqust [24]

Answer:

The answer to your question is 9 cm

Step-by-step explanation:

Data

slant height = 15 cm

height = 12 cm

radius = ?

Process

To solve this problem, use the Pythagorean theorem. The slant height is the hypotenuse, the height is the long leg and the radius is the short leg.

             c² = a² + b²

           slant height² = height² + radius²

-Solve for radius

           radius² = slant height² - height²

-Substitution

           radius² = 15² - 12²

-Simplification

            radius² = 225 - 144

            radius² = 81

-Result

            radius = 9 cm

Solve:<br> – 8 = -m<br> 2m<br> + 10
sukhopar [10]

Answer:

m = -18

Step-by-step explanation:

<u>Step 1:  Combine like terms</u>

-8 = -m + 2m + 10

-8 = m + 10

<u>Step 2:  Subtract 10 from both sides</u>

-8 - 10 = m + 10 - 10

-18 = m

Answer:  m = -18
