A pail holds 6 3 4 gallons of water. How much is this in cups? Write your answer as a whole number or a mixed number in simplest
storchak [24]
I'm assuming the pail holds 6 3/4 (not 634) gallons of water.


1 gallon= 16 cups


Multiply total gallons by cups per 1 gallon.

= 6 3/4 cups * 16 cups/gallon
convert mixed number to improper fraction

= 27/4 * 16
multiply numerators

= (27*16)/4
multiply in parentheses

= 432/4

= 108 cups


ANSWER: There are 108 cups

Hope this helps! :)

Let a, b, c, and d be non-zero real numbers. If the quadratic equation ax(cx + d) = -b(cx+d) is solved for x, which of the follo
LiRa [457]

Answer:

Option d

Step-by-step explanation:

given that a, b, c, and d be non-zero real numbers.

ax(cx + d) = -b(cx+d) \\acx^2+x(ad+bc)+bd =0

we can factorise this equation by grouping

(acx^2+xad)+)xbc+bd) =0\\ax(cx+d) +b(cx+d) =0\\(ax+b)(cx+d) =0

Equate each factor to 0 to get

x=\frac{-b}{a} , \frac{-d}{c}

Ratio of one solution to another would be

\frac{-b}{a} / \frac{-d}{c} \\=\frac{ad}{bc}

So ratio would be ad/bc

Out of the four options given, option d is equal to this

So option d is right
