Answer:

No.

Step-by-step explanation:

2(5x-3) + 6x is equal to 16x-6:

Distribute:

=(2)(5x)+(2)(−3)+6x

=10x+−6+6x

Combine Like Terms:

=10x+−6+6x

=(10x+6x)+(−6)

=16x+−6,

Which is not equal to 16x-3

Allushta [10]

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
