solve: 2x+3y=1
y=-2x+11

Answers

Answer 1

Answer:

(8, -5); x=8; y=-5

Step-by-step explanation:

i'll be solving via substitution

2x+3y=1; y=-2x+11

2x + 3(-2x +11) = 1

2x -6x +33 = 1

-4x = -32

x = 8

2(8) + 3y = 1

16 + 3y = 1

3y = -15

y = -5

(8, -5)

Check:

-5 = -2(8) + 11

-5 = -16 + 11

-5 = -5

Answer:

i believe it is 73 degrees

Step-by-step explanation:

Answer:

73°

Step-by-step explanation:

All interior angles of a triangle add up to 180°

We are given the angle measure of 17°. Since the triangle is a right triangle, it's safe to assume that the second angle is 90°.

90 + 17 = 107

180 - 107 = 73

The third angle should be 73°. Hope this helps!

Assuming you're talking about the angles of a triangle, X would be [tex]34^{.}[/tex]

Step-by-step explanation:

The sum of the angles in a triangle is 180, 180 - 32 - 80 = 68, [tex]\frac{68}{2}[/tex] is 34, so X is equal to [tex]34^{.}[/tex].

How do you solve 13 + 3 - 8x + 6 = 1 - 5x I dont get it

Answers

Answer:

x = 7

Step-by-step explanation:

How to solve your question

Your question is 13 + 3 − 8x + 6 = 1 − 5x

13 +3 - 8x + 6 = 1 - 5x

13 + 3 − 8x + 6 = 1 − 5x

Solve

Add the numbers

13 + 3 − 8x + 6 = 1 − 5x

22 − 8x = 1 − 5x

Rearrange terms

22 − 8x = 1 − 5x

−8x + 22 = 1 − 5x

Subtract  22 from both sides of the equation

−8x + 22 −22 = −5x + 1 − 22

Simplify

Subtract the numbers

−8x = -5x + 1 -22

-8x = -5x -21

Add 5x to both sides of the equation

-8x + 5x = -5x -21 + 5x

Simplify

Combine like terms

-3x = -21

Divide both sides of the equation by the same term

(-3x)/3 = (-21)/3

Simplify

Cancel terms that are in both the numerator and denominator

x = (-21)/(-3)

Divide the numbers

x = 7

The area of the polynomial is 35 square unit.

Step-by-step explanation:

It is given that area of the polygon WXYZ with its vertices at W(–3, –2), X(–3, 5), Y(2, 5), and Z(2, –2)

From the below graph it is noticed that the given polynomial is a rectangle with length 5 and width 7

The distance formula

Using the above formula we get,

The length of opposing sides are equal

Using the Pythagoras theorem, the length of diagonal WY and XZ are

Since the length of the diagonal are same, therefore the given polygon is a rectangle.

The area of a rectangle is

Where l is length and w is width.

The area of given polynomial is

Therefore the area of the polynomial is 35 square unit.

Answer:

5 cookies left

Step-by-step explanation:

First you make the fraction equal by multiplying them

2/3 multiply both numerator and denominator by 4

= 8/12

Now you divide 60 by 12 to find the amount to make the denominator 60

60 divided by 12 = 5

8/12 multiply both numerator and denominator by 5

= 40/60

So now we know the amounts

She gave 40 away so she has 20 left (60 - 40 = 20)

Now make 3/4 numerator and denominator by equal to 20

Multiply them by 5

15/20

She had 5 cookies left

The amount paid for different weights of oranges at a farmer’s market are shown below.

Answers

The answer is 8lbs because 3/2 is 1.5 and 12/1.5 is 8

Answer:

8

Step-by-step explanation:

Well just looking at the problem you can take the first line of data (2 pounds of oranges for $3) and divide that to get how much one orange would be.

So:

$3.00 / 2 = $1.50

So now we have :

1 pound of oranges = $1.50

With this info we can take the $12 on the fourth line and divide it by the price of one pound of oranges ($1.50).

Like so:

$12.00 / $1.50

=

8

We can check this by inputting the 8 on the ?

If we do so we get 8 (8 pounds of oranges) x $1.50 (Price per 1 pound of oranges) = $12.00, which matches up with the $12 price the problem has given us.

Hope this helps!
