Answer:

x = 100/3

Step-by-step explanation:

85+3x−5=180

Then we can simplify:

3x+80=180

Subtracting 80 from both sides gives:

3x=100

Dividing both sides by 3 gives our answer:

100/3 or 33 1/3

Answer:

33.3 repeating

Step-by-step explanation:

subtract 5 from 85

85-5+3x=180

80+3x=180

Subtract 80 on both sides

80-80+3x=180-80

3x=100

Divide by three

3x/3 =100/3

Turn it into a decimal

100/3=33.3

Hello!

<u>What is an x-intercept</u>:

 ⇒ <em>value of x</em> when the <em>value of y</em> equals '0'

       8x + 5y=25\\8x+5(0)=25\\8x=25\\\\x=\dfrac{25}{8}

  x-intercept is <u>25/8</u>

<u></u>

<u></u>

<u>What is a y-intercept:</u>

 ⇒ <em>value of y</em> when the <em>value of x</em> equals '0'

       8x+5y=25\\8(0)+5y=25\\5y=25\\y=5

   y-intercept is <u>5</u>

<u></u>

Hope that helps!

PLEASE HELP! 20 POINTS!!
Ann [662]

Answer:

15

Step-by-step explanation:

In this problem we need to use the numbers given. So in the problem it states that k = 20 and v = 10. We can replace the letters in the equation for the numbers that it equals so the equation can make sense so 25 - 20 + 10 because k is 20 and v is 10 I simply just replaced the letters with the numbers given in the problem. Then we can just subtract 25 - 20 which is 5 and add 10 which leaves you at a final answer of 15. Hope this helped!
