FOIL method
x^2+6x-27=0
Find the common numbers that multiply to 27 that will also equal 6.
(27x6) or (9x3)
the 6 is positive while 27 is negative so you need to use a + and - in the parenthesis.
then FOIL them
(x+9)(x-3)
FIRST: x*x=x^2
OUTSIDE: x*-3=-3x
INNER: 9*x=9x
LAST: +9*-3=-27
x^2(-3x9x)-27
x^2+6x-27
now that the equation matches you solve for x.
(x+9)=0 x=-9
(x-3)=0 x=3

193 miners need to ride the elevator to the bottom of the mine. The elevator can hold 7 miners at a time. How many miners will be in the elevator on its last trip?
Answer:
4
Step-by-step explanation:
193/7=27 with a remainder of four.
[tex]\huge \bf༆ Answer ༄[/tex]
Here's the solution ~
There are total of 193 mimers and each time the elevator can carry 7 miners, now divide the numbers and the remainder ww get gives the number of people left at last, that is also equal to the number of miners in the last trip since they are the last group among them.
[tex] \sf193 \div 7[/tex]On dividing, we get quotient = 27 and remainder as 4
therefore, 28th trip will be the last trip carrying 4 miners.
I hope that helps ~

Solve for m.
−48=12(m+4)
Enter your answer in the box.
Answer:
-8
Step-by-step explanation:
First, you distribute the right side
-48 = 12(m+4)
-48 = 12(m) + 12(4)
Simplify:
-48 = 12m+48
Solve for m
-96 = 12m
m=-8
Answer:
-8
Step-by-step explanation:
-48/12 = m+4
(-48/12) -4 = m
m = (-4) - 4
m = -8

Meg is a veterinarian. She found that 5 or, 50% of the dogs she saw this week were boxers. Steve is also a veterinarian. He found that 50% out of the 2 dogs he saw this week were boxers. Does each person need to find the part, the whole, or the percent?
Question content area bottom
Part 1
Meg needs to find the

part.
whole.
Part 2
Steve needs to find the
▼
percent.
part.
whole.
Answer:
a. Meg needs to find the part
b. Steve needs to find the percent.
Step-by-step explanation:
A. Does Meg need to find the part, the whole, or the percent.
Meg already knows the whole and the percent.
The whole is the entire number of dogs seen: 16 dogs.
The percent is 50%.
Hence, she needs to find the part: this is how many (what part) of the 16 dogs she saw were boxers.
And she can do with a simple operation:
Part = whole × percent = 16 × 50% = 8. This is 8 dogs of 16 were boxers.
B. Does Steve need to find the part, the whole, or the percent.
He already knows the part (7 of the 35 dogs were boxers) and the whole (35 dogs).
Then he needs to find the percent, which he can do using the next operation:
Percent = (part / whole) × 100 = (7/35)×100 = 20%
Step-by-step explanation:
Part 1:
Meg needs to find the whole as 50% of the dogs = 5 therefore 100% equals 10 dogs.
Part 2:
Steve saw 50% out of two dogs meaning that he only saw 1 dog that is a boxer.

Natalia is moving into a new house. All together, her furniture weighs 2,896 pounds. If it takes 2 trucks to carry all of Natalia's furniture, what is the average weight load on each truck?
Answer:
1448 Pounds per truck
Step-by-step explanation:
Divide 2896 by 2
If you haven't learned long division yet, try breaking up the number and dividing it by 2 like this:
2000/2=1000
800/2=400
90/2=45
6/2=3
Then, add them up and solve from there: 1000+400+45+3=1400+48=1448
Answer:
1448
Step-by-step explanation:
2,896/2 = 1448

there is 10 fishes in a tank.
1 dies
3 swim away
4 choke on water
2 are breathing
how many fish are in the tank ?
10
It doesn't say they jumped out of the tank.
Answer:
Im not quite sure but I think it is either 10, cause it says there are 10 fish in the tank. Either that or 8 (ill explain)
Step-by-step explanation:
1 died, but that doesnt mean it was taken out of the tank. 3 swam away, but if they are in a tank they probably just swam to a different part of the tank. 4 choke on water, but that doesnt mean they didnt recover. however, the "2 are breathing" part got me confused since the definition of breathing means taking in air and expelling stuff out...fish "breathe" water so it didnt make sense. So, if you include the 2 breathing fish there are 10, but if u dont there are 8.
I really hope this helps :)

Maria has already written Two-fifths of her 1,000-word essay. If she continues writing at the same pace of 6 1/2 words per minute, which expression shows the amount of time it will take her to write the rest of the essay?
1000 times two-fifths times 13/2
1000 times two-fifths divided by 13/2
1000 times three-fifths times 13/2
1000 times three-fifths divided by 13/2
Answer:
I think it's C
Step-by-step explanation:
if you multiply 1000 by 2/5 you would get 400 and if you divide 400 by 13/2 which is also equivalent to 6 and 1/2 you would get 15.38 which i assume is the time itll take her to finish her essay.... plus if u multiply 400 by 13/2 u get 2600 which i doubt it takes her like 43 hours to finish an essay of 1000 words
Rafi had a board that was 15 1/2 feet long. He cut three pieces off the board that are each 3 7/8 feet long. How much of the board is left?
Answer:
Step-by-step explanation:
To answer this question, first we need to figure out how much of the board Rafi cut off.
To do this, we need to multiply the length of each piece by the number of pieces he cut off.
3 7/8 = 3.875
3.875 * 3 = 11.625
Now, because we knew Rafi cut off 11.625 feet off of the board, we just need to subtract this length from the length of the entire board to find the remaining length.
15 1/2 = 15.5
15.5 - 11.625 = 3.875
There is 3.875 feet or 3 7/8 of the board left.

The number of hours a student should spend on their homework to expect a 94 on the quiz.
Mallory puts $1.00 in a jar. The following week, she puts 2 times that original amount in the jar. For each of the next six weeks, Mallory continues to double the amout of money she places in her savings jar each week.
Determine if the relationship is linear or nonlinear. Explain your choice using examples with ordered pairs. (week, amount)
We want to see if the relationship between the number of weeks and the money put in the jar is linear or not, we will see that this is not a linear equation (it is exponential).
So a linear relation is something like:
y = a*x + b
Note that for any value of x, an increase of 1 unit gives:
y = a*(x+ 1) + b = (a*x + b) + a
So for increases of 1 unit in the x-value, we have increases of "a" units on the y-value.
In the given situation we have:
In week 1 she puts $1.00 in the jar.In week 2 she puts $2.00 in the jar (now the jar has $3.00 in it)In week 3 she puts $4.00 in the jar (now the jar has $7.00 on it)In week 4 she puts $8.00 in the jar (now the jar has $15.00 on it)and so on.
Writing that as points we have:
(1, $1)
(2, $3)
(3, $7)
(4, $15)
Notice that for equal increases in the x-value, (increases of 1 unit) we don't equal increases in the y-value (first increases by $2, then by $4, etc...) So this is not a linear equation, this is actually exponential.

https://brainly.com/question/19770987
The relationship of the ordered pair that represents Mallory savings is a nonlinear relationship.
Let x represents the number of weeks, and y represents the amount put in the jar, each week.
So, we have the following highlights for 6 weeks.
Week 1: (1, 1)Week 2: (2,2)Week 3: (3,4)Week 4: (4,8)Week 5: (5,16)Week 6: (6,32)The ordered pairs can then be represented as:
[tex](x,y) = (1,1)(2,2)(3,4)(4,8)(5,16)(6,32)[/tex]
As the x values increase, the y values increase too, but the y values do not increase at a constant rate.
This means that the relationship is not linear; it is an exponential relationship.
Hence, the relationship is a nonlinear relationship.

Consider the points (-5,2) and (3,-9)
What's the horizontal distance between the two points?
Answer:
The distance between the 2 points is about 13.6
Step-by-step explanation:
Picture the 2 points on a graph, and then look at the distance between them as the hypotenuse of a right triangle. You can easily find the length of the legs of that triangle, and with those legs, you can use the pythagorean theorem to calculate the length between the points.
The length of one leg is the distance between the 2 x-coordinates, between -5 and 3, so that's 8.
[tex]3--5=3+5=8[/tex]
The length of the other leg is the distance between the y, between 2 and -9.
[tex]-9-2=-11[/tex]
That's just a distance of 11, as there's no such thing as negative distance.
Now we have the legs, so we can find the hypotenuse:
[tex]a^2+b^2=c^2\\8^2+11^2=c^2\\64+121=c^2\\c^2=185\\c\approx13.6[/tex]
