Answer 1

Answer:

x = 1 and y = -2

Step-by-step explanation:

Given that,

2x-3y = 8 ..(1)

4x+3y = -2 ..(2)

Add equation (1) and (2),

2x-3y+4x+3y = 8+(-2)

6x = 6

x = 1

Put the value of x in equation (1).

2-3y = 8

2-8 = 3y

-6 = 3y

y = -2

Hence, the value of x is 1 and that of y is -2.

Answer:

x = 17/tan75

Step-by-step explanation:

tangent = opposite/adjacent

tan75 = 17/x

xtan75 = 17

x = 17/tan75 ≈ -40.41

The measure of the value of x is 4.5.

What is the tan theta?

The length of the opposite side to the length of the adjacent side of a right-angled triangle is known as the tangent function or tangent ratio of the angle between the hypotenuse and the base.

The measure of the value of theta is 75 degress and length of the opposite side is 17.

The value of is determined in the following steps given below.

[tex]\rm Tan\theta=\dfrac{Opposite}{Adjacent}\\\\Tan75=\dfrac{17}{x}\\\\x=\dfrac{17}{Tan75}\\\\x=4.5[/tex]

Hence, the measure of the value of x is 4.5.

Like terms are terms that contain the same variables raised to the same power. Only the numerical coefficients are different. ... We combine like terms to shorten and simplify algebraic expressions, so we can work with them more easily. To combine like terms, we add the coefficients and keep the variables the same

Answer:

A)x^2-x-6

B)2x^2-12x+12

C)x^2-4

Step-by-step explanation:

A) Lets break this problem into portions the first part we trying  to distribute is  x(x-3)

X times X is X^2 and X times 3 is 3x so x^2-3x

Lets work on the second part

2(x-3)

2 times x =2x and 2 times -3 = -6 so 2x-6

And since you are supposed to add them its 2x-6+x^2-3x

x^2 can't be combined so that is seperate but 2x(+)-3x (negative overpowers positiveis) so we have -x and then -6 cant be joined with anything so

x^2-x-6

B) I'm going to go a little faster but it's essentially the same

2x(x-4)-3(x-4)

Multiply2x*x= 2x^2

2x*-4=-8x

combinde these two (2x^2-8x)

Pt.2

-3*x= -3x

-3*-4(negative and negative cancels out and it becomes positive)=12

join  (-3x+12)

and then 2x^2-8x-3x+12

you can only combine -8x-3x so -12x

2x^2-12x+12

C) this is level 3

x(x-2) + 2(x-2)

(x^2-2x) +(2x-4)

only like terms is 2x and-2x so combine and its 0

x^2-4

Kelly and Jessica have a total of 5 same-sized cookies. They want to divide them equally between the two of them. How much cookie does each girl get?

Answers

Answer:

Each girl gets 2 1/2.

Step-by-step explanation:

5 is an odd number. If you take the 4 in it and split that in half then you have 2. Then take the extra 1 from the rest of 5 and split that in half.

2 1/2.

Each girl gets two and a half cookies from a total of 5 same-sized cookies. The cookies divide into equal parts.

What is division?

Division means the separation of something into different parts, sharing of something among different people, places, etc.

The total amount of same-sized cookies = 5

In order to divide the cookies into the two parts for Kelly and Jessica the following calculation is done;

[tex]n = \frac{5}{2} \\\\ n = \frac{5}{2} \\\\ n=2.5 \\\\ n=2\frac{1}{2}[/tex]

Hence each girl gets two and a half [tex](2\frac{1}{2} )[/tex]cookies from a total of 5 same-sized cookies.

What is the intersecting chords theorem?

The intersecting chords theorem states that, the product of one whole chords segment and its external segment is equal to the product of the other whole chords segment and its external segment when two chords cross at an exterior point.

According to the intersecting chords theorem,

Substitute the values in above formula,

y x 8 = 12 x 4

y = 48/8

y = 6 centimeters,

You need to prime factorize 150. 150 = 3*5*2*5.

What we have done so far is we have split 150 into a few digits

You can add 5 to one box and 5 to the other.

Next if we add 3 to one box and 2 to the other box, then they wont be equal.

Let's try 5*6 and 5.

6 is missing from the second box, so N must be 6 to create a perfect square.

The perfect square is 900 and 30*30 = 900, so it is a perfect square.
