Answer:
60
Step-by-step explanation:
Just use similar triangles.
12/10 = 72/x
Now solve for x.
x = 72 * 10 / 12 = 60
Use your knowledge of place value to write your fraction
3 and 375/1000
now reduce. Both are divisible by 25.
3 15/40
oops, not done yet... we can still divide by 5
3 3/8
Done!
Y = -1/2x + 5 is the answer
Answer:
13.5
Explanation:
The equation to find the slope (another word for the rate of change) of the line is (y2-y1)/(x2-x1) when the given points are (x1,y1) and (x2,y2).
When we plug in the given points, (3,-7) and (5,20) we can start solving.
(y2-y1)/(x2-x1)
(20-(-7))/(5-3)
Two negatives make a positive
= (20+7)/(5-3)
= 27/2
= 13.5
I hope this helps!
121 = 112 - k • -3
9 = k • -3
k = -3
