Answer:
8:3
Step-by-step explanation:
Divide each by 12 :)
Rocco and Guilia can paint and finish together in 3 hours while Rocco alone can do it alone in 7 hours. Guilia at the rate of 1/r can finish the job expressed in the following equation. 1/3= 1/7+1/r. Getting r, r is equal to 5.25 hrs. Hence, Guilia can do painitng alone in 5.25 hrs.
Answer:
Number of advance tickets sold = 30
Number of same-day tickets sold = 20
Step-by-step explanation:
Let,
x be the number of advance tickets sold
y be the number of same-day tickets sold
According to given statement;
x + y = 50 Eqn 1
25x + 20y = 1150 Eqn 2
Multiplying Eqn 1 by 25
25(x+y=50)
25x + 25y = 1250 Eqn 3
Subtracting Eqn 2 from Eqn 3
(25x+25y)-(25x+20y) = 1250 - 1150
25x + 25y - 25x - 20y = 100
5y = 100
Dividing both sides by 5
Putting y = 20 in Eqn 1
x + 20 = 50
x = 50 - 20
x = 30
Hence,
Number of advance tickets sold = 30
Number of same-day tickets sold = 20
Length(width) = area
504 = 14(x)
504/14 = 14(x)/14
x = 504/14
x = 36
the poster is 36 centimeters long
hope this helps :D
Point-slope form is y - y1 = m (x - x1)
