pav-90 [236]3 years ago
8 0

Answer: A: 180= 90+4x+x

B: x=18

Step-by-step explanation:

1. Every triangle has a length of 180

2. So all the measurements combined would equal 180

3. So write the equation 180=90+4x+x

4. Let‘s simplfy, 180=90+5x

5. Subtract 90 from each side, 90=5x

6. Divide each side by 5, 18=x.

7. Double check our work! 90+(4*15)+18=180

The value of c from the given expression is -

<h3>Function and values</h3>

Given the following function

c(n)= −c(n−1)+1

Given the following parameters

c(1)=3

Substitute

3 = −c(3−1)+1

3 = -2c + 1

-2c = 3-1

-2c = 2

c = -1

Hence the value of c from the given expression is -1

Austin is 69 years younger than Jamie. 3 years ago, Jamie's age was 4 times Austin's age. How old is Austin now?
matrenka [14]

Answer: 26 years old

Step-by-step explanation:

  1. Create an equation with Austin as x and Jamie as x+69 (I just like workin with addition signs more)= 4(x-3)= x+69-3
  2. Simplify the equations --> 4x-12=x+66
  3. Solve the equation: 3x-12=66 --> 3x=78 --> x=26

This is the same as other age problems, just with the extra step of distributing the multiplication.
