Answer:
Step-by-step explanation:
Equation
3x + 9 + 2x = x - 2x - 3
Solution
Combine all the like terms.
3x+2x+9 = x - 2x - 3
5x + 9 = -x - 3 Add x to both sides of the equation
5x+x +9 = -x+x -3 Combine
6x + 9 = - 3 Subtract 9 from both sides of the equation
6x+9-9 = - 3-9 Combine
6x = -12 Divide both sides by 6
6x/6 = -12/6
x = - 2
Answer x = - 2

Step-by-step explanation:
Hooke's Law applies here, which is a linear relationship. It would be easier to solve this using proportions with N of force on the top and the amount of stretch in cm on the bottom. Set up with our unknown, the number of cm:
and cross multiply:
20x = 300 so
x = 15 cm
Answer:
zq+u =x
Step-by-step explanation:
z=(x-u)/q
Multiply each side by q
zq = (x-u)/q *q
zq = x-u
Add u to each side
zq+u = x-u+u
zq+u =x
Answer:
(1436.8cm³) let me know if that helps
Step-by-step explanation:
-so if the diameter is a straight line and it's 15 cm
-The formula for the sphere it would be v=4/3πr³
-The radius is going to be r=7cm
-v = 4/3 π (7cm)³
-so you would type in 4/3 x 3.14 x 7 ³ =1,436
- 3.14 or π
- you would round it to the nearest 10th (1436.8cm³)
