Answer:
im a a monkey
Step-by-step explanation:
<span>( 144 + 6 x 8 ) ÷ 3 = g
(144 + 48) </span>÷ 3 = g
192 ÷ 3 = g
64 = g or g = 64
Answer:
$4
Step-by-step explanation:
The two purchases can be written in terms of the cost of an adult ticket (a) and the cost of a student ticket (s):
7a +16s = 120 . . . . . . . . price for the first purchase
13a +9s = 140 . . . . . . . . price for the second purchase
Using Cramer's rule, the value of s can be found as ...
s = (120·13 -140·7)/(16·13 -9·7) = 580/145 = 4
The cost of a student ticket is $4.

<em>Comment on Cramer's Rule</em>
Cramer's rule is particularly useful for systems that don't have "nice" numbers that would make substitution or elimination easy methods to use. If you locate the numbers in the equation, you can see the X-patterns that are used to compute the numerator and denominator differences.
The value of a is (16·140 -9·120)/(same denominator) = 1160/145 = 8. I wanted to show you these numbers so you could see the numerator X-pattern for the first variable.

Of course, graphical methods can be quick and easy, too.
Answer:
8 quarts
Step-by-step explanation:
<u>Step One: Figure out how much 40% is by making an equation:</u>
<em>Since we are looking for a percentage, we use cross multiplication to find X.</em>

<u>Step Two: multiply 20 by 40 to start cross multiplying:</u>
<em>20 times 40 is 800, so replace the 40 by 800 in the equation.</em>

<u>Step Three: divide 800 by 100, and we will have X:</u>
<em>800/100=8</em>
<em><u>X=8 aka 8 quarts</u></em>
I hope this helps!
pls give thx and brainliest :D
