Answer:
x = 20
Step-by-step explanation:
3 (x-8) +2x = 76
3x - 24 +2x = 76
3x+2x = 76+24
5x = 100
x = 20
Answer:
Step-by-step explanation:
We are going to find the slope by lining up the points vertically and subtract, then put 2nd difference over first.
Also you could just use . It is the same thing.
( 5 , 5)
-( 1 , 3)
--------------
4 2
So the slope is 2/4 or 1/2 after reducing.
The point-slope form a line is
with a point on the line given and with slope given.
We are going to solve this for y and simplify what we can because our goal is y=mx+b; this is slope-intercept form. It is called that because it tells us the slope,m, and the y-intercept,b.
Distribute:
Add 3 on both sides:
Simplify:
Answer:
The second one because 5 is not a perfect square root. The third one because 24 is not a perfect square. Also the last one. Their all irrational because you don't know what is coming next.
Step-by-step explanation:
3 1/2 miles in 3/4 hour
so to get the average speed per hour = 7/2 * 4/3 = 4 2/3 mph
