dose anyone one know the equation to this??
find the solution to the following system of equations using substitution or elimination
Answer:
D. (2,-3)
Step-by-step explanation:
if you substitute 2 for the x value and -3 for the y value in both equations, it works out.
instead of y=3x-9 it would be -3=3(2)-9.
you solve and get -3=-3, so it's a solution.
and instead of y=-2x+1 it would be -3=2(2)+1. after solving it, you would get -3=-3 again, so it works for both equations.
Bobby is 5 less than Kylie's age. Their combined
age is 43. How old is Kylie?
Answer:
K=24
B=21
Step-by-step explanation:
x+x-5=43
2x=48
x=24
K=24
B=21
Answer:
24
Step-by-step explanation:
So the only way I think would be possible to get the answer is if you divide 43 by 2 (since Bobbie and Kylie are 2 people) then subtract 5 to get the answer?

Solve for x, round to the nearest tenth.
6
12
Answer:
its 10 tenths because 6 is closer to 10 than 0 and when you have double digits you always look at the second number so that would round to 10
6. Solve for x in each of the following equations:
a. m(x + n) =n
b. x( a + b) = b(c - x)
c. mx = n(m + x)
Step-by-step explanation:
m(x + n) = n
mx + mn = n
mx = n - mn
x = (n - mn)/m
x(a + b) = b(c - x)
ax + bx = bc - bx
ax + bx + bx = bc
x(a + b + b) = bc
x(a + 2b) = bc
x = bc/(a + 2b)
mx = n(m + x)
mx = mn+ nx
mx - nx = mn
x(m - n) = mn
x = mn/(m-n)

Which of the following cannot be the lengths of the sides of a triangle?
O 6, 8, 12
O 4,4,6
O 6, 6, 12
O 10, 8, 6
Given:
The sides of a triangles in the options.
To find:
Which of the following cannot be the lengths of the sides of a triangle?
Solution:
In a triangle, the sum of two smaller sides must be greater than the longest side, otherwise it cannot be the lengths of the sides of a triangle.
For option A,
[tex]6+8=14>12[/tex]
For option B,
[tex]4+4=8>12[/tex]
For option C,
[tex]6+6=12[/tex]
Here the sum of two smaller sides is not greater than the longest side. So, the sides 6, 6, 12 cannot be the lengths of the sides of a triangle.
For option D,
[tex]6+8=14>10[/tex]
Therefore, the correct option is C.
What value of n will make this equation correct. 3/10 n = 4/5
Answer:
n =[tex]\frac{5}{10}[/tex]
Step-by-step explanation:
Answer:
n= 2 and two thirds
Step-by-step:
this is the equation
3/10n=4/5
so to get n by itself, you multiply both sides by 10/3. I did 4/5 times 10/3 and I got 2/2/3, or two and two thirds
What is the perimeter?
Answer: 12km
Step-by-step explanation:
To find the missing side you need to use the formula a^2 + b^2 = c^2 where C is your hypotenuse.
So your formula would be 4^2 + 3^2 = c^2 ...
16 + 9 = c^2
25 = c^2 so square root both sides. Your missing side is 5km and then add all sides together to find your perimeter.

Which of the following expressions simplifies to a negative number? Select all that apply.
(-1)(-1)(-1)(-1)
(-1)(-1)
(-1)(-1)(-1)
(-1)(-1)(-1)(-1)(-1)
Answer:
Wait like all of them or some? I think it's 3 and 4.
Step-by-step explanation:
You add the two negative (negative + negative =positive). 3 and 4 have an extra left over which makes one negative, unless I did that wrong
Answer: 3 and 4
Step-by-step explanation:
If it is an odd number of (-1)s then it is negative. if it is an even number of them then it is positive.
1. If DC is an angle bisector, what is the
measure of DCB?
2. Without constructing, will the incenter lie
inside or outside this triangle? Why or why
not?
Answer:
1.
∠DCB is the half of the measure of ∠ACB as the angle bisector DC cut it in two equal parts.
m∠DCB = 1/2m∠ACB m∠DCB = 1/2(101.31°) = 50.655°2.
The incenter is the intersection of the angle bisectors.
All three angle bisectors lie inside the triangle, hence the incenter is always inside.

Answer:
X = 4.47 Y = 8.94
Step-by-step explanation:
2[tex]\sqrt{5}[/tex]= 2.23606798
2.23606798 x 2 = 4.47213596
-------
4.47213596
4.47213596^2 + 4.47213596^2 = 8.94427192^2
8.94427192^2 = 80
Square root of 80 is 8.94

A pair of pants originally cost 25 dollars but costs 45 dollars. what is the percent markup? Please help!
Answer:
The markup formula is as follows: markup = 100 * profit / cost .
Step-by-step explanation:
For example if your cost is $10.00 and you wish to markup that price by 40%, 100% + 40% = 140%. Multiply the $10.00 cost by 140% and get the retail price of $14.00.
How do you calculate a 45 markup?
Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage.
