Answer:
20 ounces of cleaner
Step-by-step explanation:
Water 48 oz is 60% of unknown total. 60% = 3/5. Create equation and solve
48= 3x/5. 240= 3x. 80 = x
Total of water, bleach and cleaner is 80 ounces
60% + 15% = 75%
100% - 75%= 25% cleaner
.25 × 80 = 20 ounces
discriminant= b^2-4ac= (-2)^2-4(4)(9)= -140<0
since discriminant <0, graph is always positive, x has no real roots
Hello there! Given the expression, we can solve through a series of steps:
1. Simplify
-5 + 7 • 1
2. Multiply (according to order of operations)
7 • 1 = 7
3. Add
