A science teacher collects 19 pints of lake water for a lab she is teaching.The lab requires each student to use 4 fluid ounces
ivolga24 [154]

Answer:

4 pints

Step-by-step explanation:

The conversion from pint to ounce is:

1 pint = 16 ounces.

The teacher collected 19 pints, that is, 19*16 = 304 ounces of lake water.

If there are 60 students, and each of them use 4 ounces, the total of lake water used is 60*4 = 240 ounces.

So, the amount of lake water left is 304-240 = 64 ounces, that is, 64/16 = 4 pints.

Are the expressions 3{y+1} and 3y+3 equivalent for any value? explain
andre [41]

Answer:

Yes

Step-by-step explanation:

The distributive property states that a(b+c) = ab+ac. Working out the first equation, we see that 3(y+1) is 3y+3. Because the second equation is 3y+3, they are also equal.
