The product of two consecutive integers is 72. The equation x(x + 1) = 72 represents the situation, where xrepresents the smaller integer. Which equation can be factored and solved for the smaller integer?
Ox2 + x - 72 = 0
O x2 + x + 72 = 0
O x2 + 2x - 72 = 0
o x2 + 2x + 72 = 0
Answers
Answer:
x^2 + x - 72 = 0
Step-by-step explanation:
x(x + 1) = 72 should be re-written in the standard form of a quadratic:
x^2 + x - 72 = 0. Same as the first answer choice.
Answer:
x^2+x-72=0

Answers
65% of the students walked. Are all of the other students on buses? Are there both public buses AND private buses?
Assuming that you need to know BOTH kinds of buses, try this:
65% of the students walked, so since 100% - 65% = 35% then this means that 35% of the students were on buses.
Since we know that there are 360 more walkers than bus riders, then one equation we know is: 65% of S = 360 + 35% of S (let S = total # of students)
.65 S = 360 + .35 S
- .35 S = - .35 S Subtract .35 S from both sides
.30 S = 360 Divide both sides by .30 (or .3)
.30 .30
S = 1,200 so we know that this is the total number of students, but that is not what was asked.
They want to know how many are on buses and specifically how many are on public buses, if I read this correctly.
Since the walkers = 65% of 1,2000 and we know of means TIMES, then
.65 (1,200) = 780 walkers
1,200 total students minus 780 walkers = 420 bus riders
Now, if there is not a misprint and we really have to figure out the public bus riders as compared to the private bus riders, then remember the ratio from above in the question: 4 bus: 3 public buses
Now if I read this right, that means that 3/4ths of the bus riders were on public buses
so 3/4 of 420 means 3/4 times 420 = 3 times 105 = 315 public bus riders (which coincidentally leaves 105 private bus riders, but since they are private we don't know much about them. Ha-Ha..... I made a lame joke.)
So your answer is 315 public bus riders
