Question 931221: At a bakery there are 45 different kinds of breads and sweets. If the ratio of sweets to breads is 4:5, how many types of breads are there? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = breads
y = sweets
---
x + y = 45
y/x = 4/5
---
x + y = 45
y = (4/5)x
---
put the system of linear equations into standard form
---
x + y = 45
(4/5)x - y = 0
---
x + y = 45
0.8x - y = 0
---
copy and paste the above standard form linear equations in to this solver:
