Combine like terms.<br><br> - 2/3p + 1/5 - 1 + 5/6p

DaniilM [7]

Answer:

1/6 p -4/5

Step-by-step explanation:

- 2/3p + 1/5 - 1 + 5/6p

When I combine like terms, I put them next to each other.

- 2/3p + 5/6p+ 1/5 - 1

We need to get a common denominator of 6 for the p terms

-2/3 *2/2 p + 5/6 p

-4/6p + 5/6 p

1/6 p

We need to get a common denominator of 5 for the contant terms

1/5 - 1*5/5

1/5-5/5

-4/5

Substituting these in

2/3p + 5/6p+ 1/5 - 1

1/6 p -4/5

tomas bought a bottle of shampoo that held 10.5 fluid ounces. he uses 1/16 of the shampoo every time he washes his hair. how man

Airida [17]

1) 10.5 = 10 1/2 = 21/2 ounces in bottle

2) 21/2 * 1/16 = 21/32 ounces one use

3) 21/32 * 6 = 63/16 ounces six use

4) 21/2 - 63/16 = 168/16 - 63/16 = 105/16 = 6 9/16 ounces left
