Answer:
y= mx + c (m- slope, c- y intercept)
or, y = x +3
The answer is -6/7
When you divide fractions, you keep the first fraction the same, change the sign to a multiplication symbol, and flip the second fraction…so 1/2 would be 2/1. Then you just multiply.
Answer:
24 white marbles, 36 black marbles
Step-by-step explanation:
System of Inequalities:
x + y > 20
2/5y + 3/5x > 20
solve first inequality for 'y':
y > 20 - x
Use substitution to solve for 'x':
2/5(20 - x) + 3/5x > 20
8 - 2/5x + 3/5x > 20
1/5x > 12
x > 60
2/5 of 60 = 24
3/5 of 60 = 36
