SOLVE FOR x IN THE DIAGRAM BELOW

Answers

3x+2x+80=180
5x+80=180
5x=100
ANSWER IS x=20

So to check if the answer is correct:
Angle 3x is 3x20 = 60 degrees
Angle 2x is 2x20= 40degreee

60+40+80= 180 degrees
Well, the base of it is a 180° angle and the middle angle is 80°. That leaves 3x and 2x.

3 x 20 = 60
2 x 20 = 40
60 + 40 = 100
100 + 80 = 180
180°

PLEASE SHOW WORK

Answers

Answer:

12.5%

Step-by-step explanation:

12.5 %
100% = 200
x% = 25
100% = 200(1)
x% = 25(2)
100/x% = 200/25
x%/100% = 25/200
x = 12.5% 25 is 12.5 percent of 200

The formula for the surface area of the bottom cushion is

A = 2wl + 2lh + 2hw (w is width, l is length, h is height)

w = 18, l = 21, h = 3

A = 2(18)(21) + 2(21)(3) + 2(3)(18)

A = 2(378) + 2(63) + 2(54)

A = 756 + 126 + 108

Solve for Variable: 3x + 7 < 16
A. x > 3
B. x < 5
C. x > 6
D. x < 3

Answers

Answer:

D. x < 3

Step-by-step explanation:

3x + 7 < 16

To solve, we have to isolate x.

3x + 7 < 16

Subtract 7 from both sides :

3x < 9

Divide 3 from both sides :

x < 3

Now in some cases, you could say that the inequality sign would switch, but this is only when you divide by a negative sign, so keep that in mind.

Values of the elements in the Matrix are A₂₁ = -2, A₂₂ = 0, A₂₃ = 4, A₃₃ = 5.

What is the matrix?

A collection of numbers lined up in rows and columns to form a rectangular array is called a matrix. The elements, or entries, of the matrix, are the integers. In addition to many other areas of mathematics, matrices have numerous applications in the fields of engineering, physics, economics, and statistics.

given, the sum of each row is equal to the sum of each column equals the sum of all diagonals.

Since, the sum of column C₁ = 3 + -2 + 1 = 2

the sum of Row R₁ = 3 + A₂₁ + 1 = 4 + A₂₁

Since this is equal to the sum of column C₁

thus, 4 + A₂₁ = 2

A₂₁ = -2

the sum of column C₂ = A₂₁ + A₂₂ + 4

C₂ = -2 + A₂₂ + 4

C₂ = A₂₂ + 2

Since this is equal to the sum of column C₁

2 = A₂₂ + 2

A₂₂ = 0

the sum of Row R₂ = -2 + A₂₂ + A₂₃

R₂ = -2 + 0 + A₂₃

Since this is equal to the sum of column C₁

2 = -2 + A₂₃

A₂₃ = 4

the sum of Row R₃ = -1 + 4 + A₃₃

R₃ = -3 + A₃₃

Since this is equal to the sum of column C₁

2 = -3 + A₃₃

A₃₃ = 5

therefore, the values of the matrix's elements are A₂₁ = -2, A₂₂ = 0, A₂₃ = 4, A₃₃ = 5.

What is Pythagoras theorem?

The Pythagorean theorem, or Pythagorean theorem, illustrates the relationship between the three sides of a right-angled triangle. The square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle, according to the Pythagorean theorem.

We know,

Kyle held a balloon 8 feet off the ground.

Ava is standing 15 feet directly to the right of Kyle.

So, height = 8 ft and distance = 15 ft

Using Pythagoras theorem

x² = 8² + 15²

x² = 64+ 225

x = 17 unit

Thus, the value of x is 17 unit.

4d-1+105=180

Answers

Answer:

I think it's "d=19"

D would equal 19. First, you combine like terms, so add -1 and 105 together to get 104. Then you have to subtract 104 from both sides. After that you get 76 on the right side. Then you would have to divide 4 from both sides to get d by itself. Lastly, 76 divided by 4 is 19.

Answers

Answer:

1 3/10 (SORRY IF ThIS IS WRONG)

Step-by-step explanation:

3/4 mile x 6 = 4 1/2

(we multiply by 6 because to get 60 minutes/1 hour you need to multiply 10 minutes by 6)

60/15=4

(we will multiply by 4 because we need that to get 1 hour)

4/5 x 4 = 3 1/5

4 1/2 - 3 1/5 = 4 5/10 - 3 2/10 (we do that so we can subtract easier)

4 5/10 - 3 2/10 = 1 3/10
