23 and 3
23 + 3 = 26 and 23 - 3 = 20
Answer:
$11.4
Step-by-step explanation:
P = collection by abby
Q = collection done by julia
R = collection done by kim
S = collection done by jeanie
Given that :
collection of abby = 3 x collection of julia
P = 3 Q
so
Q = P/3
collection of kim = collection of abby - $25
R = P - $25
collection of jeanie = 2 x collection of abby
S = 2 P
also , P + Q + R = $55
P + (P/3) + (P - $25) = $55
P = $34.3
Q = collection of julia = P/3 = $34.3/3 = $11.4
P = 3 Q
The sum, because the product is for multiplication the quotient is for division and the difference is for subtraction. So that leaves the sum. It’s for addition.
Answer:
9 hours, 20 minutes
Step-by-step explanation:
When two ferries work together, they transport a day's cargo in 7 hours
The speed proportion or ratio of larger ferry to smaller ferry is given as 3 : 1
The sum of the ratio = 4 (3 + 1)
This means that it will take the smaller ferry = 7 x 4 hours to work alone = 28 hours, since the larger ferry is faster by 3.
Therefore, when larger ferry works alone, it will take it (7 x 4)/3 = 9.33 hours.
9.33 hours = 9 hours, 20 minutes.
