Answer:
28%
Step-by-step explanation:
If x represents the fractional increase in the number of mathletes, and if problem-solving speed is jointly proportional to their speed and their number, we want ...
(1 +25%)(1 +x) = (1 +60%)
1 +x = 1.60/1.25 = 1.28
x = 0.28 = 28%
The team size must increase by 28% to solve all of the problems on time.
95% is greater than 17/20
The equation would be
5x= 470
470/5 = X
X = 94
Answer=94
X = adult tickets
y = student tickets
x + y = 273
2x = y
In order to solve this, use substitution:
x + 2x = 273
3x = 273 (divide by 3 on both sides)
x = 91 adult tickets
If you want to check your answer, plug in your answer into the second equation and then use both answers for the first equation:
2x = y
2(91) = y
y = 182 student tickets
x + y = 273
91 + 182 = 273
273 = 273 (If both sides are the same value, this means your answer is correct.)
Best of luck, friend.
