8 + 12n – 4n – 7 Another problem pls dont troll or i will report you :)

Answers

Answer 1

Answer:

Step-by-step explanation:

Do u see any similarities between the numbers? Both 12 and -4 have a variable(N). 8 and -7 dont have a variable, so u have to calculate them individually.

One thing to remember is just because there is a minus sign(-) or a plus sign(+) does not mean its addition or subtraction. its the value of the number. the sign to the left of the number is its value. so left of 12 is plus(+), so its a positive. left of 4 is a minus sign(-) so its a negative 4. lastly, left of 7 is minus sign(-), which means its negative 7. now u add.

lets add the variables first:

12n + (-4n) = 8n

add the regular numbers:

8 + (-7) = 1

so its 8n + 1

Step-by-step explanation:

cost of tank tops

20 / 5 = $4 each

cost of t-shirts

35 / 5 = $7 each

7 - 4 = $3

Answer:

$3

Step-by-step explanation:

1.Approach

To solve this problem, one must first find the cost of each product. This can be done by diving the price by the amount of each product. After finding the unit price of each product, one will subtract the cost of the tank-top from the cost of the t-shirt.

2.The unit price of a t-shirt

It is the given that 5 t-shirts cost $35. Divide the price of the shirts by the number of shirts to find the cost of each individual shirt.

35 ÷ 5 = 7

Each individual t-shirt costs $7.

3.The unit price of a tank-top

It is given that 5 tank-tops cost $20. Divide the price of the tank-tops by the number of tank-tops to fund the unit price of each tank-top.

20 ÷ 5 = 4

Each tank-top costs $4.

4.Find out how much more each shirt costs

Now subtract the price of the unit price of the tank-top from the unit price of the t-shirt.

(t-shirt) - (tank-top)

= 7 - 4

= 3

Does it lie inside, outside, or on the circle?​

Answers

Answer:

Given circle:

(x - 4)² + y² = 25

The center is at (4, 0) and the radius is 5 units

Lets find the distance from (7, 2) to the center of the circle:

[tex]d = \sqrt{(7 - 4)^2 + (2 - 0)^2} = \sqrt{9+4} = \sqrt{13} < 5[/tex]

Since d < 5, the point (7, 2) lies inside the circle

It contains multiple points. If you’re looking specifically for a point plug the number that is on the x axis into the equation then solve for y.

Answer:

(0, -2) --> Y-Intercept

Step-by-step explanation:

y - 3 = -2( x + 1 )

y - 3 = -2x - 2

y= -2x -2

Answer: 222cm

Step-by-step explanation:

To find the area of this composite shape you will have to split them into 2 shapes; a rectangle and a triangle.

To work out the area of the rectangle you have to do 15×12= 180

Then, to work out the area of the triangle, you use the formula base times height divided by 2.

7×12=84

84÷2=42

Then to work out the total area of both the rectangle and the triangle, you have to add the area of both.

180+42=222cm

Step-by-step explanation:

10^2 + 7^2 = 149

x ≈ 12.2, 12

Therefore, the value of the hypotenuse [tex]x[/tex] is [tex]12[/tex].

What is the pythagorean theorem?

The Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle.

It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides.

Here given that,

[tex]B=7,P=10[/tex]

As we know,

[tex]H^2=B^2+P^2[/tex]

Substitute the given values in the formula is

[tex]x^2=(7)^2+(10)^2\\\\x^2=49+100\\\\x^2=149\\\\x=\sqrt{149}\\\\x=12[/tex]

Hence, the value of the [tex]x[/tex] is [tex]12[/tex].

x = 45°

Step-by-step explanation:

We know that (2x + 45)° and x° are adjacent angles, so they add up to 180°.

(2x + 45) + x = 180

3x + 45 = 180

3x = 180 - 45

3x = 135

x = [tex]\frac{135}{3}[/tex]
