Hi!
77.78% is correct answer.
Explanation: <em><u>This question is super super easy. First you had to divide 14 by 18 and it gave us 14/18=0.7778. Then multiplied by the answer from first step by 100 to get that answer, and it gave us 0.7778*100=77.78%is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day. -Charlie</u></em>
539 should be your answer. Not 100% sure.
The second one and the fourth one.
Step-by-step explanation:
As the problem states, it takes 166.5 gallons of water in 3 mins. Since it states it is a proportional relationship, we know that 166.5/3 is the number of gallons pumped in 1 minute. We can write this as g(the number of gallons) = 166.5/3 * m(the number of minutes) ! In additon, 166.5/3 is equivalent to 55.5, which gives us the second and the fourth equation correct!
<span>The sum of two numbers is 48.
a + b = 48
;
If one third of one number is 5 greater than one sixth of another number,
a = b + 5
multiply both sides by 6, cancel the fractions
2a = b + 30
2a - b = 30
</span><span>use elimination to solve this
a + b = 48
2a - b =30
-------------Addition eliminates b, find a
3a = 78
a =
a = 26
then
26 + b = 48
b = 48 - 26
b = 22</span>
