We are given the equation:

0.6 x + 4.8 = 7.2

 

In this case, the multiplication property of equality states that whatever is multiplied on one side should also be multiplied on the other side. Now we need to find the number that will make everything a whole number, in this case 5. Multiply everything by 5:

5 * (0.6 x + 4.8 = 7.2)

3 x + 24 = 36

However we can see that we can still further simplify the equation by multiplying everything by 1/3:

(1/3) * (3 x + 24 = 36)

x + 8 = 12

or

x = 4

Two physics students are doing a side competition during a game of bowling, seeing who can toss a ball with the larger momentum.

Answer:

she should beat a speed of  v₂ = 6.04 m/s in order to win the competition

Step-by-step explanation:

Since the momentum p is defined as

p = m*v

where

m= mass of the ball

v= velocity of the ball

denoting 1 and 2 as the first and second bowler , then to reach the momentum of the first bowler

p₂=p₁

therefore

m₁*v₁ = m₂*v₂

v₂ = v₁ * (m₁/m₂)

replacing values

v₂ = v₁ * (m₁/m₂) =8.6 m/s * (4.5 kg/6.4 kg ball) = 6.04 m/s

then since the momentum p = m*v increases with increasing v (at constant m)  , she should beat a speed of  v₂ = 6.04 m/s in order to win the competition

How do you answer this and please show work if you solve?
nikklg [1K]
To solve this, simply switch the X and y variables within one equation, and upon doing so, see and check if it equals to the other equation.

f(X) = -X + 4/5
Y = -X + 4/5
X = (-Y+4)/5
5X = -Y + 4
-Y = 5X - 4
Y = -5x + 4

Yes, by looking at the second equation it is an inverse of the first one.
