4/5(2x+5)−4=1<br><br> x = 1 1/4<br> x = 1 2/5<br> x = 5/8<br> x = 3 1/5
tia_tia [17]
The answer is x=5/8. The reason for this is when you divide it equal 0.625 then when you multiply that by 2 it equals 1.25. After you do that you add 5 which is 6.25. Now we divide 4/5 which is 0.8. Now, we multiply 6.25x0.8=5. 5-4=1. Therefore your answer is 5/8. Hope this helps :)

What is the slope of the line that contains these points?x 15,17,19,21 y -10,2,14,26
9966 [12]

Answer:

  6

Step-by-step explanation:

The slope (m) can be found using the formula ...

  m = (y2 -y1)/(x2 -x1)

Any pair of points will do. We can use the first two.

  m = (2 -(-10))/(17 -15) = 12/2

  m = 6

The slope of the line is 6.
