Answer:
1 =x-5 = as pytanerosa tery says
23
Step-by-step explanation:
Step-by-step explanation:
-7(-3r+2)=3r-6
Distribute the - 7
21r-14=3r-6
Add 14
21r=3r+8
Subtract 3r
18r=8
Divide 18r by 8
2.25 should be the answer to r.
Answer:
The value of the maximum distance the spring will be compressed
x = 0.143 m= 14.3 cm
Step-by-step explanation:
Given data
Mass m = 1.5 kg
h = 0.9 m
k = 1500
Since the book is released from a height h = 0.9 m above the top of the spring. so the total distance
y = h + x
Now in that case for the spring


By rearranging the above equation we get

Put all the values in above equation we get

By solving the above equation we get
x = 0.143 m= 14.3 cm
This is the value of the maximum distance the spring will be compressed.
Percent change = (new number - old number)/(old number) * 100
percent change = (127 - 136)/(136) * 100
percent change = -6.62%
Since the percent change is negative it is a percent decrease.
Answer: 6.62% decrease.
Answer:
Step-by-step explanation:
2)
x + 14
= -0.87
x +
= - 
x +
= - 
x = -
-
x = - 
3)
x -8
= 1.5
x -
= 
x =
+ 
x = 
x = 
4)
x -
= - 7 
x -
= - 
x = -
+
x = - 
5)
- x = 6 
=
+ x
-
= x
-
= x
x = - 
6)
-33.754 - x = 28.05
-33.754 - 28.05 = x
- 61.804 = x
x = - 61.804
