Answer: 131°

Step-by-step explanation:

Supplementary angles are the angles that when we add them together, their sum is equal to 180°.

From the question, we are informed that angle w and angle v are supplementary angles and angle v=49.

V + W = 180°

49° + W= 180°

W = 180° - 49°

W = 131°

Answer:

A

Step-by-step explanation:

The product of expression 2x² - 3xy + y² and 2x - 4y will be;

⇒ 4x³ - 14x²y + 14xy² - 4y³

Option c is true.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The equations are,

2x² - 3xy + y² and 2x - 4y

Now,

The product of the expressions are find as;

⇒ (2x² - 3xy + y²) × (2x - 4y)

⇒ 2x²×2x - 2x² × 4y - 3×2×x²×y + 3xy×4y + y²×2x - y²×4y

⇒ 4x³ - 8x²y - 6x²y + 12xy² + 2xy² - 4y³

⇒ 4x³ - 14x²y + 14xy² - 4y³

Thus, The product of expression 2x² - 3xy + y² and 2x - 4y will be;

⇒ 4x³ - 14x²y + 14xy² - 4y³

Answer: C

Step-by-step explanation: because you it has the greatest with an ration is 4 by 8

===========================================================

Explanation:

n = number of nickels

d = number of dimes

Since each nickel is 5 cents, and each dime is 10 cents, we can say

5n = value of all the nickels (ignore the dimes) in cents

10d = value of all the dimes (ignore the nickels) in cents

5n+10d = value of all the coins (nickels+dimes) in cents

5n+10d = 85 is the equation we're after

-----------------------

Extra Info:

We don't have enough info to be able to solve for n and d.

The list of all possible solutions are

Note how each time n drops by 2, d goes up by 1.

This is because 2 nickels = 1 dime.

In other words, for every 2 nickels we take away, we add on 1 dime. This works in reverse as well (for every dime removed, add 2 nickels).

The equation to represent the given situation is 5n+10d = 85.

Given that, Andre's coin jar contains 85 cents.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Now, n = number of nickels and d = number of dimes.

Since each nickel is 5 cents, and each dime is 10 cents, we can say

5n = value of all the nickels (ignore the dimes) in cents

10d = value of all the dimes (ignore the nickels) in cents

So equation is 5n+10d = value of all the coins (nickels + dimes) in cents

That is, 5n+10d = 85

Therefore, the equation to represent the given situation is 5n+10d = 85.

Answer:

  P = (5, 5)

Step-by-step explanation:

For the given division, ...

  P = (2B +3A)/5

  P = (2(8, 14) +3(3, -1))/5 = (16+9, 28-3)/5 = (25, 25)/5

  P = (5, 5)

_____

For some division ratio of AP : PB = p : q, we have ...

  (P -A)/(B -P) = p/q

  q(P -A) = p(B -P)

  P(p+q) = pB +qA . . . . rearranging

  P = (pB +qA)/(p+q) . . . . . the formula we used above

Hi there !

three consecutive numbers a ; b ; c

b = a + 1

c = a + 2

a + b + c = 45

replace b ; c

a + (a + 1) + (a + 2) = 45

3a = 45 - 3

3a = 42

a = 42 : 3

a = 14

Answer:

x = 50

Step-by-step explanation:

x/240 = 82/100

240 : 100 = 2.4

so 240 is divided with 2,4 giving 100, this will work with 82 too. So, 82 × 2.4 = 196,8

Answer : x = 196,8

prove :

196,8/240 = 82/100 = 41/50

The solutions to the system of equations are (2, -1) and (-2,3)

The equations are given as:

[tex](x - 2)^2 + (y - 3)^2 = 16[/tex]

x  + y - 1 = 0

Make y the subject in x  + y - 1 = 0

y = 1 - x

Substitute y = 1 - x in [tex](x - 2)^2 + (y - 3)^2 = 16[/tex]

[tex](x - 2)^2 + (1 - x - 3)^2 = 16[/tex]

Evaluate

[tex](x - 2)^2 + (-x - 2)^2 = 16[/tex]

Expand the equations

[tex]x^2 - 4x + 4 + x^2 + 4x + 4 = 16[/tex]

Evaluate the like terms

[tex]2x^2 + 8 = 16[/tex]

Subtract 8 from both sides

[tex]2x^2 = 8[/tex]

Divide by 2

[tex]x^2 = 4[/tex]

Take the square roots of both sides

x = ±2

Substitute x = ±2 in y = 1 - x

y = 1 - 2 = -1

y = 1 + 2 = 3

Hence, the solutions to the system of equations are (2, -1) and (-2,3)
