Answer:
2nd option
Step-by-step explanation:
r + 1 = 23 ( subtract 1 from both sides )
r = 22 ( multiply both sides by 3 to clear the fraction )
r = 66 ( divide both sides by
)
r =
×
( rationalising the denominator )
r =
= 33
3(x-1)=2x+5
3x-3=2x+5
3x-2x=3+5
x=8
Answer:

Given : 
To Find: How many seconds does it take for the golf ball to hit the ground?
Solution :
Since we are given an equation : 
Where H denotes height
t denotes the number of seconds elapsed since the ball was hit.
When he golf ball to hit the ground at that time the height becomes 0
So, put H = 0 in the equation






Thus it take 4 seconds for the golf ball to hit the ground
In this question, we are required to find the total amount he paid to buy the shirt.
It is given that sales tax is 5.5 % over the amount paid.
The cost price of the shirt = $ 24.
The total amount will be = Cost price + 5.5 % of Cost price
Or
Total amount paid = $ 24 × 1.055 (i.e. 100 % + 5.5 %)
Total amount = $ 24 + (5.5 % × $ 24)
Total amount paid = $ 24 + $ 1.32 = $ 25.32
