hello bro
Find the solution of the system of equations. 3x-8y = 19
3x + 5y = -46
(-7,-5)
Step-by-step explanation:
3x-8y = 19
minus
3x + 5y = -46
0x - 13y = 65
- 13y = 65
÷-13
y = - 5
Substitute y = - 5 into one of the functions:
3x-8y = 19
-8 x - 5 = 40
3x + 40 =19
-40
3x. = - 21
÷3
x= - 7
Solution is (-7,-5)

Step-by-step explanation:
4a=16
7+a+b=16
2b+c=16
a+b+c+d=16
Solve by completing the square.
w2 – 16w – 19 = 0
Answer:
Factoring w2-16w+19
The first term is, w2 its coefficient is 1 .
The middle term is, -16w its coefficient is -16 .
The last term, "the constant", is +19
Step-1 : Multiply the coefficient of the first term by the constant 1 • 19 = 19
Step-2 : Find two factors of 19 whose sum equals the coefficient of the middle term, which is -16 .
-19 + -1 = -20
-1 + -19 = -20
1 + 19 = 20
19 + 1 = 20
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
w2 - 16w + 19 = 0

Step-by-step explanation:
These are alternate interiour angles, and the theorem states that they are congruent, so set both expressions equivalent to each other:
[tex]\displaystyle 10x - 5 = 8x + 9 \Rightarrow \frac{-14}{-2} = \frac{-2x}{-2} \\ \\ \boxed{7 = x}[/tex]

Soo, I need help with these 3 math problems. I don't have enough time to do them before I go to bed.
So these apple pies have a ratio of 15 apples to 3 pies. How many apples do you need for 12 pies?
Answer:
60
Step-by-step explanation:
since 15 apples makes 3 pies you divided 15 by 3 and get 5. 5 apples for one pie so that would be 5 x 12 = 60
Answer:
Since with 15 apples we are able to make 3 pies, this means that in each pie there are 5 apples (15apples divided by 3 pies = 5 apples.)
If there are 12 pies we simply have to multiply 12x5 which equals 60, this means that if we needed to make 12 pies we would need 60 apples.
15apples:3pies = 60apples:12pies
Miguel spent $11 to buy 16 apples and oranges. How many of each type of fruit did he buy F apples cost $0. 75 and oranges cost $0. 65
Answer:
Step-by-step explanation:
x + y = 16
.75x + .65y = 11
75x + 65y = 1100
-75x - 75y = -1200
-10y = -100
y= 10 organes
x + 10 = 16
x = 6 apples
x= 6 apples
y = 10 oranges

If the nth term of a number sequence is 4n^2+ n find the first 3 terms and 10th term
Answer:
1st term = 7, 2nd term = 18, 3rd term = 39, 10th term = 403
Step-by-step explanation:
To find the 1st term substitute 1 for n in the equation:
4(1)² + 1 = (4 × 1) + 3 = 4 + 3 = 7
To find the 2nd term substitute 2 for n in the equation:
4(2)² + 3 = (4 × 4) + 3 = 16 + 3 = 18
To find the 3rd term substitute 3 for n in the equation:
4(3)² + 3 = (4 × 9) + 3 = 36 + 3 = 39
To find the 10th term substitute 10 for n in the equation:
4(10)² + 10 = (4 × 100) + 3 = 400 + 3 = 403

.
There are 56 marbles in total in the bag and each is equally likely to be chosen.
Work out how many red marbles there must be.
Step-by-step explanation:
Multiply 56 by 7/8 to determine the amount of red marbles.
*56 can be put over 1.
Multiply;
[tex] \frac{56}{1} \times \frac{7}{8} = \frac{392}{8} [/tex]
Simplify by dividing by 8;

Determine if the two triangles are necessarily congruent. If so, fill in a flowchart proof
to prove that they are.
L
The triangles
necessarily congruent.
Answer:
Step-by-step explanation:
solve for x and y.
A.
B.
C.
D.
Step-by-step explanation:
the height from the 90° angle (which is y here) in a right-angled triangle is the square root of the Sergent lengths of the Hypotenuse.
y = sqrt(3×9) = 3×sqrt(3)
and x we get via Pythagoras :
x² = y² + 9² = 27 + 81 = 108
x = sqrt(108) = sqrt(36×3) = 6×sqrt(3)
so, A is correct.

A high school is having a talent contest and will give different prizes for the best 5 acts in the show. First place wins the most money, and each place after that wins $50 less than the previous place. Part A Create a model that can be used to determine the total amount of prize money based on the value of the first place prize Enter your model in the box provided.
The model that can be used to determine the total amount of prize money based on the value of the first place prize is as follows;
Total amount of price money = 5x - 500
The prices are given to the best 5 acts. The first place wins the most money and each place after that wins $50 less than the previous place. The pattern follows a sequence.
What is a Sequence?Sequence is a list of things (usually numbers) that are in order. Therefore,
let
the first price = x
The common difference of the sequence would be - 50.
To create a model that can be used to determine the total amount of prize money based on the value of the first place prize can be done as follows;
x , x - 50, x - 100, x - 150, x - 200Therefore,
Total amount of price money = x + x - 50 + x - 100 + x - 150 + x - 200
Total amount of price money = 5x - 500

Which operation should you perform first in the expression 7 × 2 by the power of 3
Answer:
If the 7 x 2 is in parenthesis then you would do the 7 x 2 first then do 14 by the power of 3. If there is no parenthesis and the power of 3 is hovering next to the 2 then you would do 2 to the power of 3 and then multiply that by 7.
Step-by-step explanation:
PEMDAS. Whatever is in parenthesis gets solved first, then exponents and so on and so forth.
