what’s the value of x and what’s the angle?

=================================================

Explanation:

Adding an even number to an odd number always results in an odd number

even + odd = odd

odd + even = odd

So if 'a' is odd, adding 2 onto it (even number), leads to an odd result of a+2.

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

Extra Information (optional section)

If you are curious why the two equations shown above are true, then here's a proof.

Let 'a' be an odd number. This means a = 2k+1 for some integer k. We add 1 to any multiple of 2 and it goes from even (2k) to odd (2k+1).

If we made b an even number, then b = 2m for some integer m.

Adding 'a' and b gives us...

c = a + b

c = ( a ) + ( b )

c = ( 2k+1 ) + ( 2m )

c = (2k+2m) + 1

c = 2(k+m) + 1

c = 2n + 1 .... where n = k+m

The result a+b is an odd number since it is in the form 2*(integer)+1

It verifies the claim that odd+even = odd.

So this shows that a+2 is also odd, since we let b = 2.

Step-by-step explanation:

since y is the total cost and x is the total hours at 20 dollars an hour then we have 20 times the number of hours to get y

Answer:

y = 20x

Step-by-step explanation:

Cost of x hours is:

20x

Hence, since y = total cost,

y = 20x

Answer:

Total money left with Jamie = £13

Step-by-step explanation:

Jamie received pocket money = £26

He spent on sweets = 10% of total pocket money

Expense on magazines = 25% of the total money

Expense on games = 15% of the pocket money

Total expenditure on sweets, magazines and games = [tex]\frac{10}{100}+\frac{25}{100}+\frac{15}{100}[/tex]

= [tex]\frac{50}{100}[/tex] Or 50% of the pocket money he received

Therefore, money left with Jamie = 50% of total money he received as pocket money

= [tex]\frac{50}{100}\times 26[/tex]

= £13

Answer:

753.6 meters

Step-by-step explanation:

Given :

Fiona races a BMX in a dirt course.

The course in circular in shape. The radius of the dirt course is 60 meters.

So the circumference of the dirt course is given by :

[tex]$C = 2 \pi r$[/tex]

   = 2 x 3.14 x 60

   = 376.8 meters

So the total outer distance of the circular dirt course is 376.8 meters.

Therefore, the total distance that Fiona covers in the two laps of the race is

= 376.8 + 376.8

= 753.6 meters

10.5 + 6.5y - 0.5

6.5y + 10

Answer and Step-by-step explanation:

To solve, we would multiply by the reciprocal of the portion Jada has read, and multiply that number to 75.

The reciprocal means the the value, but flipped, so [tex]\frac{3}{5}[/tex] will become [tex]\frac{5}{3}[/tex].

Now we do 75 times [tex]\frac{5}{3}[/tex]/

[tex]\frac{75 * 5}{3} \\\\\\\\\frac{375}{3} \\\\\\\\125[/tex]

So, there are 125 total pages in the book.

Principal, P = $ 3000

Duración o período, t = 3 meses

La cantidad final, A, que pagará después de 3 meses:

Usando la fórmula de interés simple:

A = P (1 + rt)

A = 3000 (1 + 0,08 * 3)

A = 3000 (1 + 0,24)

A = 3000 (1,24)

11) x = 145°

12) x = 40°

Step-by-step explanation:

9) 180-91 = 89

10) x = 118° because it is alternate interior to 118

11) x-30 = 115,     x = 145

12) 4x-15 = 145,    4x = 160,   x = 40

Step-by-step explanation:

sin x = 7/9

x = sin^-1 (7/9)

simply using a calculator.

Answer:

x = 51 degrees

Step-by-step explanation:

(to find x, use sine)

Sine = [tex]\frac{opposite}{hypothenuse}[/tex]

⇒ Sine x = [tex]\frac{7}{9}[/tex]

⇒ [tex]\frac{7}{9}[/tex] = 0.78

⇒ Sine x = 0.78

then calculate what Sine-1 of 0.78 is:

⇒ Sine-1 of 0.78 = 51.26

x = 51.26

Round to the nearest degree:

51.26 ⇒ 51 degrees

b

Answer:

Step-by-step explanation:

x + y = 4

x = 4 - y

2x - 3y = 6

2x - 3y = 6

2(4 - y) - 3y = 6

8 - 2y - 3y = 6

-5y = 6 - 8

-5y = -2

y = 2/5

x = 4 - y

x = 4 - 2/5

x = 20/5 - 2/5

x = 18/5

The surface area of the rectangular prism 158 square feet.

The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any object is called the surface area.

The rectangular prism will have six faces. The surface area will be calculated as:-

Surface area = 2 ( 3x5) + 2 ( 8x3) + 2(8x5)

Surface area = 30 + 48 + 80 = 158 square meters

Therefore the surface area of the rectangular prism is 158 square feet.
