Answer:

angle 2 = 133

angle 3 = 47

Step-by-step explanation:

angle 2 and angle 1 are supplementary, so they equal 180. 180- 47=133

angle 3 and angle 4 are supplementary, so they equal 180. 180- 133=47

Answer:

x = -55

Step-by-step explanation:

7 + x/5 = -4

Combine the constants.

x/5 = -11

Multiply both sides by 5 to simplify the denominator.

x = -55

Check.

7 + (-55)/5 = -4

7 + (-11) = -4

7 - 11 = -4

-4 = -4

Your answer is correct.

Hope this helps!

Answer:

[tex]7 + \frac{x}{5} = - 4 \\ \frac{x}{5} = - 4 - 7 \\ = - 11 \\ x = - 11 \times 5 \\ = - 55[/tex]

Answer:

[tex]m^{4}n^{5}[/tex]

Step-by-step explanation: ( I'm a student, I'm not really good at explaining maths )

When dividing variables with exponents, you subtract the exponents that has the same variables, like this:

[tex]m^{16-12}n^{10-5}[/tex]

Simplifying this becomes:

[tex]m^{4}n^{5}[/tex]

The number that when you multiply it by 0.9 and subtract 6.3 from the product, you get 4.5 is 12.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Let the number be x.

According to the problem, we have:

0.9x - 6.3 = 4.5

Adding 6.3 to both sides, we get:

0.9x = 10.8

Dividing both sides by 0.9, we get:

x = 12

Therefore,

The number we're looking for is x = 12.

Answer:

[tex]\frac{22}{30} = \frac{11}{15}[/tex]

and

[tex]\frac{176}{7} = 25 \frac{1}{7}[/tex]

Step-by-step explanation:

First make all the fractions into improper fractions

[tex]1\frac{5}{6} = \frac{11}{6} \\\\2\frac{1}{2} = \frac{5}{2} \\\\3\frac{1}{7} = \frac{22}{7}[/tex]

After doing that put them back into the problems

Problem 1)

[tex]1\frac{5}{6}[/tex]  ÷ [tex]2\frac{1}{2}[/tex] , plug in the improper fractions

[tex]\frac{11}{6}[/tex] ÷ [tex]\frac{5}{2}[/tex]

to divide, you need to flip the second fraction and multiply

[tex]\frac{11}{6}[/tex]· [tex]\frac{2}{5}[/tex] = [tex]\frac{22}{30}[/tex]

then reduce

[tex]\frac{22}{30} = \frac{11}{15}[/tex]

Problem 2)

[tex]3\frac{1}{7}[/tex]÷ [tex]\frac{1}{8}\\[/tex]

Plug in improper fraction

[tex]\frac{22}{7}[/tex] ÷ [tex]\frac{1}{8}\\[/tex]

Then flip second fraction and multiply

[tex]\frac{22}{7}[/tex] · [tex]\frac{8}{1}[/tex]

Multiply

[tex]\frac{176}{7}[/tex]

Reduce, or make it a mixed number

[tex]\frac{176}{7} = 25 \frac{1}{7}[/tex]

Answer:

36

Step-by-step explanation:

Given that :

Rotation about polygon's center = 20°

To carry the polygon onto itself Angle of rotation is obtained by :

360° / n

Where n is the number of sides in the polygon :

360° / n = 20°

360° = 20 * n

360 = 20n

n = 360 / 20

n = 18

Hence, the polygon has 18 sides or a multiple of 18

Step-by-step explanation:

You can't do anything about the numbers with variables afterwards, so you just list those and you just add and subtract the numbers without variables.  Since the top and bottom are the same, you just list it once.  Sorry, not the best explanation.  Please let me know if I am wrong.  It's been a while since I had to any type of algebra.

Answer:

1.   y = -10x - 5

2.  [tex]y = \frac{9}{5}x - 4[/tex]

3.  [tex]y = -\frac{5}{4}x + 5[/tex]

4. y = 7x + 5

Step-by-step explanation:

use y = mx + b

m = slope

b = y-intercept

1. Slope= -10, y- intercept = -5

   y = -10x - 5

2. Slope= - 9/5, y- intercept = -4

   [tex]y = \frac{9}{5}x - 4[/tex]

3. Slope= -5/4, y- intercept = 5

    [tex]y = -\frac{5}{4}x + 5[/tex]

4. Slope= 7, y- intercept = 5

    y = 7x + 5

Answer:

Area of the running track = 6900 m²

Step-by-step explanation:

Length of a football pitch = 120 m

Width of the football pitch = 80 m

Area of the football pitch (Inner rectangle) = Length × Width

                                                                      = 120 × 80

                                                                      = 9600 m²

If a running track (width = 15 m) is built around the football pitch,

Length of the outer rectangle = 120 + 2×(15)

                                                  = 120 + 30

                                                  = 150 m

Width of the outer rectangle = 80 + 2×(15)

                                                = 110 m

Area of the outer rectangle = 150 × 110

                                              = 16500 m²

Therefore, area of the track around the football pitch = Outer rectangle - Inner rectangle

= 16500 - 9600

= 6900 m²

Area of the running track = 6900 m²

Answer: $4.25

Step-by-step explanation:

Let the cost of the hotdog be x

Since a hamburger costs $1.75 more than a hot dog. Then, the cost of the hamburger will be:

= x + 1.75

We are further told that the group buy 6 hot dogs and 3 hamburgers for a total of $27.75. This can then be represented in an equation as:

6 hot dogs + 3 hamburger = $27.75

(6 × x) + 3 × (x + 1.75) = 27.75

6x + 3x + 5.25 = 27.75

9x = 27.75 - 5.25

9x = 22.50

x = 22.50/9

x = 2.50

The hotdog cost $2.50

Cost of hamburger = x + 1.75

= $2.50 + $1.75

= $4.25

Answer:

x=4, y=0. (4, 0).

Step-by-step explanation:

3x-4y=12

x=-2y+4

-----------

3(-2y+4)-4y=12

-6y+12-4y=12

-10y=12-12

-10y=0

y=0/-10=0

x=-2(0)+4=0+4=4

Answer:

Step-by-step explanation:

if x=-2y+4

3x-4y=12 becomes

3(-2y+4)-4y=12

-6y+12-4y=12

-10y+12=12

-10y=0

y=0

since x=-2y+4

x=-2(0)+4

x=4

so the solution is the point (4,0)
