Answer:
a) 7:10
Step-by-step explanation:
An example of this would be having seven blue marbles and three red marbles in a jar. If you randomly select one, the chance of that marble being blue is seventy, because 10 (total number of marbles) divided by seven (number of blue marbles) is 0.70, and if you convert this to a whole number (by multiplying it by 100) you get 70.
The system of equations is:
2x+1.5y=20
x+y=12
When you solve it you get:
x=4 hamburger bun packages
y=8 hot dog bun packages
The two numbers would be 12 and 8 because 12 is 4 more than 8 and so the sum of 12 and 8 is 20.
