10 pints.
We know that there are 8 pints in a gallon. We have one gallon so we already have 8 pints.
Then there is a .25 gallon, this is equivalent to one-fourth of a gallon. So 1/4 times 8 is 2.
8 + 2 is 10 pints.

Calculate S30 for the arithmetic sequence defined by {an}={3.1n-2}
timurjin [86]

Answer:

c) 1,381.5.

Step-by-step explanation:

First term = 3.1 *1 - 2 = 1.1

2nd term = 3.1*2 - 2 =  4.2

3rd term = 3.1*3 - 2 = 7.3

so the common difference d = 3.1.

S30  = (30/2) [ 2* 1.1 + (30-1) * 3.1)]

= 1,381.5.

Solve: 4x + 6 = 8x - 18
sladkih [1.3K]

Answer:

x=-3

Step-by-step explanation:

4x+6=8x+18

We simplify the equation to the form, which is simple to understand  

4x+6=8x+18

We move all terms containing x to the left and all other terms to the right.  

+4x-8x=+18-6

We simplify left and right side of the equation.  

-4x=+12

We divide both sides of the equation by -4 to get x.  

x=-3
