m=(-2-(-5))/(-7-(-7))
m=(-2+5)/(-7+7)
m=3/(0)
undefined
x=-7.
Find the value of n
Plz help me fast and send the answer
Answer:
n is 113
Step-by-step explanation:
Is an isosceles triangle so the base angles are equal
therefor angles sum up to 180
46 + x + x = 180
46 + 2x = 180
2x = 180 - 46
2x = 134
x = 67
now to find n
the sum of angles on a straight line equals 180
n + x = 180
n + 67 = 180
n = 180 - 67
n= 113
Answer:
the base angle of an isosceles triangle are equal
let the base angle be y°
46° + y° + y° = 180°(sum of angles in a ∆)
46° + 2y° = 180°
2y° = 180° - 46°
2y° = 134°
y° = 134/2
y°=67°
n+y=180°[sum of angles on a straight line]
n+67=180°
n=180-67
n=113°

The population of Fantasy City doubles each month. When will the city be half populated if it will be fully populated in 10 months.
Using an exponential function, it is found that the city will be half populated in 9 months.
The population of Fantasy City doubles each month, hence, after t months, the population is given by:
[tex]P(t) = P(0)2^{t}[/tex]
In which P(0) is the initial population.Fully populated in 10 months, hence, the full population is:
[tex]P(10) = P(0)2^{10} = 1024P(0)[/tex]
Hence, half populated is [tex]P(t) = \frac{1024P(0)}{2} = 512P(0)[/tex], hence:
[tex]P(t) = P(0)2^{t}[/tex]
[tex]512P(0) = P(0)2^{t}[/tex]
[tex]2^t = 512[/tex]
[tex]2^t = 2^9[/tex]
[tex]t = 9[/tex]
The city will be half populated in 9 months.

Devon has $900 in a savings account. The interest rate is 7% per year and is not
compounded. How much interest will she earn in 2 years?
Use the formula i = prt, where i is the interest earned, p is the principal (starting amount),
is the interest rate expressed as a decimal, and t is the time in years.
=
Answer:
$ 12600
Step-by-step explanation:
According to the question, you have to find the simple interest that Devon earn after 2 years,
You can use this formula to find that.
I = P r tHere,
P = principal ( $ 900)
r = rate ( 7%)
t = time ( 2 years)
Let us solve now.
I = p × r × t
= $ 900 × 7% × 2 years
= 6300 × 2
= $ 12600

At Cheesecake Factory, the cost of your meal before the tip is $77.23. You leave a 15% tip. How much
money did you leave for tip? What is the total cost of your meal?
Answer:
$88.81
Step-by-step explanation:
to find tip, multiply 77.23 and .15 to get $11.58
total cost = meal + tip
total cost = 77.23 + 11.58 which equals $88.81

Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance ticket and one same-day ticket is $70. For one performance, 25 advance tickets and 35 same-day tickets were sold. The total amount paid for the tickets was $2050. What was the price of each kind of ticket?
Answer:
You can use the method of substitution.
Let the advance and same-day tickets be x and y respectively.
x + y = $70 ---> (1)
25x + 35y = $2050 ---> (2)
From Statement (1):
Let (1) × 25
25x + 25y = $1750
10y = $2050 - $1750
= $300
y = $300 ÷ 10
= $30 ---> (3)
From Statement (3):
Substitute (3) into (1)
x + $30 = $70
x = $70 - $30
= $40
Advance ticket: $40
Same-day ticket: $30

Mary has some chocolates. If she shares them equally among 4 friends or 5 friends, there are always 2 extra chocolates left. What is the possible number of chocolates Mary could have?
Answer:
22 chocolates
Step-by-step explanation:
First, let x represent the number of chocolates Mary has. Since she always has 2 extra chocolates, the number of chocolates distributed to her friends would be x - 2. And x - 2 is the least common multiple of 4 and 5 because x - 2 chocolates are evenly distributed among 4 and 5 friends. The LCM of 4 and 5 is 20, so x - 2 is 20. Mary has 22 chocolates.

Answer:
x = -3
Step-by-step explanation:
The two angles shown are corresponding angles, meaning that they have the same value. Because of this, we can create an equation to solve for the value of x.
2x + 9 = 7x + 24
Remember, those two angles are similar, and that's why we can make the two values equal to each other. First, let's remove 7x from both sides.
2x - 7x + 9 = 7x - 7x + 24
-5x + 9 = 24
Then, we'll remove 9 from both sides.
-5x + 9 - 9 = 24 - 9
-5x = 15
Finally, we'll divide both sides by -5 to isolate x and figure out what it is equivalent to.
-5x/-5 = 15/-5
x = -3
And there it is... the value of x. Hopefully that's helpful! :)

Answer:
y=-x-1
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-4-(-2))/(3-1)
m=(-4+2)/2
m=-2/2
m=-1
y-y1=m(x-x1)
y-(-2)=-1(x-1)
y+2=-x+1
y=-x+1-2
y=-x-1

Answer:
19
Step-by-step explanation:
Angle ZYW is congruent to angle YWX, so the 3 angles must add to 180.

5x + 85 = 180
5x = 95

The triangle and rectangle have the same perimeter.find the value of x.
Answer:
X=2
Step-by-step explanation:
Triangle
3x+18
Rectangle
6x+12
Same perimeter:
3x+18=6x+12 //-12
3x+6=6x //-3x
6=3x //:3
2=x
Answer:
x = 2
Step-by-step explanation:
Perimeter of triangle = a + b + c
Perimeter of rectangle = 2(l + b)
=> x + 5 + x + 6 + x + 7 = 2(2x - 1 + x + 7)
=> 3x + 18 = 2(3x + 6)
=> 3x + 18 = 6x + 12
=> 3x - 6x = 12 - 18
=> -3x = -6
=> x = -6/-3
=> x = 2
