X = 47 + 9y
xy = 1860
y(47 + 9y) = 1860
47y + 9y² = 1860
9y² + 47y - 1860 = 0
> using a quadratic equation solver on a calculator but you can also use the quadratic equation = [-b+/- √(b²-4ac)]/(2a)
> only integer solution is x = 12
12y = 1860
y = 155
integers are 12 and 155
A) 60o because similar triangles have corresponding angles equal so then by Angle Sum Property of Triangles you will get 60o

Number of dog food packages bought by Byron is 300
Step-by-step explanation:
- Step 1: Given number of bird food packages = b. Find the number of packages for the other animal foods.
Number of hamster food packages = b.
Number of dog food packages = 4b
Number of cat food packages = 1/2 of 4b = 2b
Total food packages = 600
⇒ b + b + 4b + 2b = 600
⇒ 8b = 600
⇒ b = 600/8 = 75
- Step 2: Calculate the amount of dog food
∴ 4b = 4 × 75 = 300
