Answer is -4. good luck !
Let's solve this problem step-by-step.
STEP-BY-STEP SOLUTION:
We will be using simultaneous equations to solve this problem.
Let's first establish the two equations we will be using to solve the problem.
Let number no. 1 = x
Let number no. 2 = y
Equation No. 1 -
x = y + 3
Equation No. 2 -
x + y = 27
To begin with, we will substitute the value of ( x ) from the first equation into the second equation to solve for ( y ).
Equation No. 2 -
x + y = 27
( y + 3 ) + y = 27
y + y = 27 - 3
2y = 24
y = 24 / 2
y = 12
Next we will substitute the value of ( y ) from the first equation into the first equation to solve for ( x ).
x = y + 3
x = ( 12 ) + 3
x = 15
FINAL ANSWER:
Therefore, the two numbers are 15 and 12.

The law of conservation of energy. The energy due to work performed on the skateboarder is converted into kinetic energy such that:
Work=Kinetic Energy
So 380=(1/2)(35)(7-Vo). I don’t have a calculator so..
Assumptions we made:
No energy loss, all work went into the energy of motion of the skateboarder. In the real world, this is not possible because some of the energy can be loss through friction of the skateboarder to the ground etc.
