Find a number you can multiply by the bottom of the fraction to make it 10, 100, or 1000 and multiple both top and bottom by that number then write down just the top number putting the decimal point in the correct spot.
Answer:
Step-by-step explanation: 4x/3=11/7
Now , we cross multiply =4x*7=11*3
=28x=33
x=33/28
ANSWER:33/28 or you can even convert into a mixed fraction
hope this helps

Answer:
The maximum height that the ball will reach is 81 ft
Step-by-step explanation:
Note that the tray of the ball is given by the equation of a parabola of negative main coefficient. Then, the maximum value for a parabola is at its vertex.
For an equation of the form
So
the t coordinate of the vertice is:
In this case the equation is:
So
Therefore
Finally the maximum height that the ball will reach is
Step one: 3x+4y=20; 10=40-3y
Step two: 3y=40-10, so y=(40-10)/3=10
Step three: 3x+4*10=20
Step four: 3x=20-40=-20, so x=-20/3=-6.66666...~ -6.67
