Step-by-step explanation:

1. 5+9(1+4n)=-30

-5               -5

--------------------

9 (1 + 4n) = -35

/9                /9

----------------------

(1 + 4n) = -35/9

1 + 4n = -35/9

-1            -1

------------------------

4n = -44/9

/4        /4

-----------------------

n = -11/9

2. 6(3-8c)=-31

   /6            /6

---------------------

(3 - 8c) = -31/6

3 - 8c = -31/6

-3          -3

---------------------

-8c = -49/6

/-8      /-8

-----------------------

c = 49/48

3. -21=8+9(f-3)

8 + 9 (f - 3) = -21           we switched sides here

-8                  -8

------------------------

9 (f - 3) = - 29

/9              /9

-------------------------

f - 3 = -29/9

 +3        +3

--------------------------

f = -2/9

4. 9k-7-5=-25

9k - 12 = -25

    +12     +12

--------------------

9k = -13

/9      /9

--------------------

k = -13/9

5. 8(3y-6)=-25

   /8            /8

------------------------

(3y-6) = -25/8

3y - 6 = -25/8

    +6        +6

-----------------------

3y = 23/8

/3      /3

-----------------------

y = 23/24

6. 16=-5(2b-7)

-5(2b-7) = 16            we switched sides here

/-5             /-5

--------------------

(2b-7) = -16/5

2b - 7 = -16/5

     +7     +7

--------------------

2b = 19/5

/2      /2

---------------------

b = 19/10

Answer:

(4x+1)= 81

Step-by-step explanation:

4x+1= 81

4x= 81 - 1

4x= 80

x= 80/4

x= 20

Answer:

4x+1=81(vertically opposite angles)

x=20 degrees

Step by step explanation:

4x+1=81

4x   =81-1

  4x=80

     x=20

Answer:

15

Step-by-step explanation:

(2x-1)+(x+17)+(4x-15)=106º

2x+x+4x=7x

-1+17-15=1

7x+1=106º

         -1

7x=105º

/7     /7

x= 15

Answer:

Putting x= 2

[tex]( - 5) \times 2 = - 10 \\ - 10 = - 10[/tex]

putting x = -2

[tex]( - 5) \times ( - 2) = - 10 \\ 5 \times 2 = - 10 \\ 10 = - 10 \\ this \: is \: not \: correct \: equation[/tex]

putting x = 50

[tex]( - 5) \times 50 = - 10 \\ - 250 = - 10 \\ this \: is \: also \: not \: correct \: equation[/tex]

so, x = 2 is applicable.

Answer:

A)270°

Step-by-step explanation:

Hi!

If this is a measures. We know that; this measures total depress is 360°.

So we can do this:

360° - 90°= 270°

Option B is correct, if ABC measures 90°, then  the measure of arc AC is 90 degrees.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

Given that ABC measures 90°

We have to find the measure of arc AC.

Arc is the part or segment of the circumference of a circle which is drawn between two points and an angle and length of arc is known as arc length.

The measure of an arc is equal to the measure of the central angle that intercepts it".

We have  θ = 90⁰

From the above mentioned statement i.e.,

"The measure of an arc is equal to the measure of the central angle that intercepts it".

We can say that the measure of arc AC is 90 degrees.

Hence, If ABC measures 90°, then  the measure of arc AC is 90 degrees.

Step-by-step explanation:

Answer:

77 cm²

Step-by-step explanation:

We know that

Area of trapezium = ½ (a + b) × h

Area = ½ × (10 + 12) × 7

Area = ½ × 22 × 7

Area = 11 × 7

Area = 77 cm²

Length of parallel sides = 10 cm and 12 cm

Height = 7 cm
