Answer:

easy peasy mate

Step-by-step explanation:

if u see the right angle shown in the red, then the question is half solved for you,

cz if that is there, then with the angle next to it which constitutes the angle with the variable x, we will get,

=> 50 + (3x + 4) = 90

=> 3x + 4 = 40

=> 3x = 36

=> x = 12

Jessica and Martha each have a bag of cookies with unequal quantities. They have 30 cookies total between the two of them. Each

Basile [38]

Answer:

Part 1) The inequality that describes the relationship between the number of cookies each one of them has is $x^{2} -30x+224\geq 0$

Part 2) Jessica has at least 2 cookies more than Martha

Step-by-step explanation:

Part 1) Find the inequality that describes the relationship between the number of cookies each one of them has

Let

x----> the number of cookies when Jessica started

30-x ----> the number of cookies when Martha started

we know that

Each of them ate 6 cookies from their bag

The cookies left in each bag are

(x-6) ----> Jessica

and (30-x-6)=(24-x) ---> Martha

The product is equal to (x-6)(24-x)

The product of the number of cookies left in each bag is not more than 80.

$(x-6)(24-x)\leq 80\\ \\24x-x^{2}-144+6x\leq 80\\ \\-x^{2} +30x-144-80\leq 0\\ \\-x^{2} +30x-224\leq 0$

Multiply by -1 both sides

$x^{2} -30x+224\geq 0$

Part 2) Solve the quadratic equation

$x^{2} -30x+224\geq 0$

Solve by graphing

The solution is x=16 cookies

(30-x)=30-16=14 cookies

therefore

The number of cookies when Jessica started was 16 cookies

The number of cookies when Martha started was 14 cookies

The number of cookies left in each bag is equal to

Jessica

16-6=10 cookies

Martha

14-6=8 cookies

Jessica has at least 2 cookies more than Martha

What is the value of v?

frosja888 [35]

Answer: v = 32 degrees

Step-by-step explanation:

The polygon theorem states that for any polygon with n sides, the sum of the interior angles is (n - 2) × 180

The given polygon has 6 sides. Therefore, n = 6

The sum of the angles in the polygon is

(6 - 2) × 180 = 3 × 180 = 540 degrees

Therefore,

119 + 134 + 108 + v + 47 + 2v + 2v - 28

Collecting like terms, it becomes

119 + 134 + 108 + 47 - 28 + v + 2v + 2v = 540

380 + 5v = 540

5v = 540 - 380

5v = 160

v = 160/5

v = 32 degrees
