7 0

Answer:

18 ducks

Step-by-step explanation:

add the parts of the ratio 7 + 6 = 13

divide the total by 13 to find one part of the ratio

$\frac{39}{13}$ = 3 ← 1 part of the ratio

7 parts = 7 × 3 = 21 ← number of swans

6 parts = 6 × 3 = 18 ← number of ducks

The sum of two numbers is 15. four times the smaller number is 60 less than twice the larger number. what is the larger number?

kirza4 [7]

X = smaller number, y = larger number
x + y = 15.....x = 15 - y
4x = 2y - 60

4(15 - y) = 2y - 60
60 - 4y = 2y - 60
60 + 60 = 2y + 4y
120 = 6y
120/6 = y
20 = y <==== larger number is 20

x + y = 15
x + 20 = 15
x = 15 - 20
x = - 5
