I hope that help ✌️
(13 + x)/(50 - x ) = (2/1)
Cross Multiply
2(50-x) = 1(13 + x)
100 - 2x = 13 + x
add 2x to both sides
100 -2x + 2x = 13 + x + 2x
100 = 13 + 3x
Subtract 13 from both sides
100 - 13 = 13 - 13 + 3x
87 = 3x
divide both sides by 3
29 = x
(13 + 29)/(50-29) = 42/21 = 2 to 1 ratio
Answer:
puppies - 22
Step-by-step explanation:
since the ratio is 2:3, there are 5 parts in total. (2+3=5)
55/5=11 then multiply by parts
puppies- 2×11=22
adults- 3×11=33
check answer by adding- 22+33=55
