Answer:
n <=6.5
Step-by-step explanation:
Six less than two times a number is no more than 7
2n-6 <=7
Add 6 to each side
2n-6+6 <=7+6
2n <=13
Divide by 2
2n/2 <=13/2
n <=6.5
We are given
Tobias dropped a tennis ball from a height of 60 meters. The time in seconds it takes for the ball to fall 60 feet is 0.25(radical60).
so, time is

we have to approximate it's value
First approximation set:
we know that

we can take sqrt all the sides

we can simplify it

Divide all sides by 4

Second approximation set:

Divide all sides by 4


Third approximation set:

Divide all sides by 4


so, we get
......Answer
Answer:
x = d/ a + c / a - b
Step-by-step explanation:
a( x + b ) - c = d
add c on both sides
a( x + b) = d + c
ax + ab = d + c
subtract ab from both sides
ax = d + c - ab divide both sides by a
ax / a = d/ a + c/ a - ab / a
x = d/ a + c / a - b
