Answer: x=18

Step-by-step explanation: 7x−11=5x+25

Step 1: Subtract 5x from both sides.

7x−11−5x=5x+25−5x

2x−11=25

Step 2: Add 11 to both sides.

2x−11+11=25+11

2x=36

Step 3: Divide both sides by 2.

2x /2 = 36 /2

x=18

Answer:

x=18

<span>$15000 compounded continuously at a rate of 3% for 11 years will yield a final amount of $20864.52. The equation for continuously compounded interest A = Pe^rt where A=End Amount P=Inital Amount e=eulers number (approximately 2.7) r=growth rate per year and t= time. So for your problem, p= 15000 r= 3 and t= 11. Plug that into your calculator and you'll get $20864.52.</span>

A blue billiard ball with mass m crashes into a red billiard ball with the same mass that is at rest. The collision results in t

sammy [17]

Draw a diagram to illustrate the problem as shown below.
Each ball has mass = m.
The initial velocity of the blue ball = u.
The initial velocity of the red ball = 0.

Initial total momentum is
P1 = m*u + m*0 = mu
Final momentum is
P2 = mv + 3mv = 4mv

Because momentum is conserved,
mu = 4mv
u = 4v

Answer:
The velocity of the blue ball before the collision is 4v.
