The width of border is 1.5 feet
<h3><u>
Solution:</u></h3>
Given that small garden measures 9 ft by 13 ft
A uniform border around the garden increases the total area to 192 ft square
To find: width of border
Let the width of border be "x"
Then the new measures of garden are (9 + 2x) feet and (13 + 2x) feet
The total area of garden = 192 square feet
<em><u>Let us solve the above equation by quadratic formula</u></em>
Using the above formula,
For 
, we have a = 4 ; b = 44 ; c = -75
Substituting the values of a = 4 ; b = 44 ; c = -75 in above quadratic formula we get,
Since "x" cannot be negative,
we get x = 1.5
Thus width of border is 1.5 feet
Answer:
$7.50
Step-by-step explanation:
3/4 of the original price
Original price: $10
So we need 3/4 of $10
10 ÷ 4 = 2.5
2.5(3) = 7.5
3/4 of $10 = 7.5, so the price is now $7.50

Answer:
7 hours 30min
Step-by-step explanation:
Step one :
Given data
We are told that Erica can paint 1 room in 5hours
Her work rate is 1/5 room per hour
And also with the assistance of her friend they can paint 1 room in 3 hours
Hence their combined work rate is 1/3 room per hour
Step two
The combined work expression is
1/A+1/B=1/T
Where A=Erica's work rate
B=Rachael's work rate
T=combined work
1/5+1/B=1/3
1/B=1/3-1/5
1/B=5-3/15
1/B=2/15
B=15/2
B=7.5 hours
It will take Rachel 7 hours 30min to paint the room
The amount of pizza Mark would have is
Find the common denominators first. 2/12 + 3/12 = 5/12. Two slices of the 6 slice pizza is 1/3 or 4/12.
