Answer:
29/5 =x
Step-by-step explanation:
25 = 5x − 4
Add 4 to each side
25+4 = 5x − 4+4
29 = 5x
Divide each side by 5
29/5 = 5x/5
29/5 =x
Answer:
28/21
Step-by-step explanation:
You would do y1 - y2 for the numerator which gets you 28. Then you would do x1 - x2 for the denominator which gets you 21. The rate of change is also the slope.
Hope this helps!
Answer:
a=19
Step-by-step explanation:
Since it is a parallelogram, adjacent angles are supplementary, or add to 180 degrees.
In this parallelogram, 5a+1 and 3a+27 are adjacent. Therefore, when added, they should equal 180.
5a+1+3a+27=180
Combine like terms
(5a+3a) + (1+27) = 180
8a +28 =180
Now, solve for a, by isolating it.
Subtract 28 from both sides
8a+28-28=180-28
8a=152
Divide both sides by 8
8a/8=152/8
a=19
