Let the number be x.
Then, the number increased by 3 will be x + 3.
According to question,
x(x + 3) = 54
x² + 3x = 54
x² + 3x - 54 = 0
By middle term factorisation,
x² + 9x - 6x - 54 = 0
x(x + 9) - 6(x + 9) = 0
(x + 9)(x - 6) = 0
Equating to zeroes and we get,
x + 9 = 0
x = -9 (First value)
and,
x - 6 = 0
x = 6 (second value)
In a horse race, how many different finishes among the first 3 places are possible if 7 horses are running? (Exclude ties)
There are a possible___different finishes.
Answer:
7 x 6 x 5 = 210
Step-by-step explanation:
its a combination's problem.
7 horses are eligible for first place.
6 of those are eligible for 2nd given that one of the 7 finished first.
similarly 5 of the remaining are eligible for 3rd place given 2 horses have taken the first 2 spots.
therefore 7 x 6 x 5 possible combinations = 210 combinations.

Like and give 5 star rating
Please brainlest
Answer:
m<2 is 49 and m<1 is 131
Step-by-step explanation:
180-131 equals 49, so m<2 is 49
m< is 49, so 180-49 which is 131, so m<1 is 131

18. You and your friend are selling your old CDs. Your friend sells 14 the first
day and x the next day. You sell y the first day and 6 the next day. Write an
expression that shows that the total number of CDs sold both ddays. Rewrite
your answer using the Commutative Property of Addition
9514 1404 393
Answer:
= x + y + 20
Step-by-step explanation:
There are a couple of ways you could write this.
friend sales + your sales
= (14 +x) +(y +6)
= (x +14) +(6 +y) . . . . commutative property used twice
= x +14 +6 +y = x +20 +y
= x + y + 20 . . . . . . . commutative property used again
__
first-day sales + second-day sales
= (14 +y) + (x +6)
= (y +14) +(6 +x) . . . . commutative property used twice
= y +14 +6 +x = y +20 +x
= y +x +20 . . . . . . . . commutative property used again
= x + y + 20 . . . . . . . and again

We also used the associative property (to move parentheses) and the properties of addition of integers to simplify the sum. We have chosen to put the variables in lexicographical order, a sort of standard.

what is s?????
I will give BRAINlIEST if u explain how to solve these plz!!!
Answer:
i dont have any idea.....my brain is full of BTS
Step-by-step explanation:
Question 4: [tex]\frac{8}{1}[/tex]
Question 5: [tex]\frac{4}{5}[/tex]
Question 6: [tex]\frac{2.5}{1}[/tex]
Question 7: [tex]\frac{1}{1}[/tex]
Step-by-step explanation:The way to solve these types of questions, also know as "slope" is solved in the format [tex]\frac{y-y}{x-x}[/tex] (y minus y over x minus x) which also can be known as [tex]\frac{rise-rise}{run-run}[/tex] (rise minus rise over rune minus run). To solve this you can choose any two sets of numbers (the top and the bottom of a chart is 1 set) and you use its numbers to find the slope. One important rule when solving for slope is to never write your answer in decimal form and rarely write your answer as a whole number always answer questions in fraction form!!!! Anyway, the y and the x are already given so no need to find those as well. Here's the solving of all questions:
4.for this question I choose the number sets:[tex]\frac{24}{3} and, \frac{32}{4} in. ..equation... written... as, \frac{24-32}{3-4}[/tex]
so, now the easy part, 24-32=-8
Next we solve the bottom, 3-4=-1
so we end up with [tex]\frac{-8}{-1}[/tex] and when we simplify it can be written as [tex]\frac{8}{1}[/tex] or just 8 (I recommend to always write in fraction form because some teachers will remove points if its not in fraction form).
5.Now, for the rest of the problems I wont explain the solving process.
[tex]\frac{60}{185} and\frac{100}{235} written...as,\frac{60-100}{185-235}[/tex]
60-100=-40
185-235=-50
[tex]\frac{-40}{-50} simplify...to,\frac{4}{5}[/tex]
6.[tex]\frac{12.5}{5} and\frac{25}{10} written...as,\frac{12.5-25}{5-10}[/tex]
12.5-25=-12.5
5-10=-5
[tex]\frac{-12.5}{-5}simplify...to,\frac{2.5}{1}[/tex] or 2.5 (I recommend to always write in fraction form because some teachers will remove points if its not in fraction form).
7.[tex]\frac{4}{2} and\frac{5}{3} written...as,\frac{4-5}{2-3}[/tex]
4-5=-1
2-3=-1
[tex]\frac{-1}{-1}simplify...to,\frac{1}{1}[/tex] or 1 (I recommend to always write in fraction form because some teachers will remove points if its not in fraction form).
Hope this helped, please give mw brainiest I spent half an hour on this :D
-Thanks for your time.
can someone tell me the answer simplified
Answer
7xy+2xt
Step-by-step explanation:
Can someone please help, I will give brainiest. If possible explain please.
Step-by-step explanation:
The angles (8x + 28) and (4x - 7) are supplementary to each other so we can write
[tex](8x + 28) + (4x - 7) = 180 \Rightarrow 12x + 21 = 180[/tex]
or
[tex]x = 13.25[/tex]
Also, note that the angle (4x - 7) and [tex]\angle{TQS}[/tex] are vertical angles, which means that they are equal to each other. Therefore,
[tex]\angle{TQS} = 4x - 7 = 4(13.25) - 7 = 46°[/tex]
please solve thank you

What is the coefficient of the first term in this expression?
4r+q3r2+8q2r
Answer:
4
Step-by-step explanation:
2. Describe ALL of the key features
The y-intercept is 2 because the line intercepts the y-axis at 2. The slope is negative because it is going down from the top left to the bottom right. The slope is -1 because the change in y over change in x results in 1 and it is negative. The equation for the line is y = -x + 2
I hope this helps, have a nice day! :D
Can please help me simplify this please
3/8
6/15
3/8 -> 3/8 (it is fully simplified)
6/15 -> 2/5 (dividing the top and the bottom by 3)
Have a nice day!
