Find the value of X<br>

arsen [322]

Answer:

x = 118

Step-by-step explanation:

1. All the angles in a pentagon add up to 540, so to find the value of x, we can use this equation x + 122 + 103 + 98 + 99 = 540.

2. (Solving)

Step One: Simplify both sides of the equation by adding like terms.

(x) + (122 + 103 + 98 + 99) = 540
x + 422 = 540

Step Two: Subtract 422 from both sides.

x + 422 - 422 = 540 - 422
x = 18

Camryn practices the trumpet every 11^\text{th}11

Snowcat [4.5K]

Answer:

in 33 days

Step-by-step explanation:

Trumpet practice is every 11 days. Flute practice is every 3 days.

You need the Least Common Multiple (the LCM) of the two numbers, 3 and 11.

Since 3 and 11 are prime, the LCM of 3 and 11 is their product.

LCM = 3 * 11 = 33

Answer: in 33 days

You can also solve this by listing multiples of 3 and 11 until you find the smallest number that is a multiple of both 3 and 11.

Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, ...

Multiples of 11: 11, 22, 33, 44, ...

The smallest multiple of both 3 and 11 is the smallest number that shows in both lists. It is 33.

the number of even integers between 1 and 103 is the same is the same as the number of odd integers between 4 and x. what is the

Ksju [112]

# of numbers between 1 & 103: 102
Half of that would be even numbers. So, 51 even numbers.
Between 4 and x, there are 102 numbers. 4+102=106. 4+106=x. 106=x

0=(x-8) (3x-5) show all work

GrogVix [38]

Answer:

x = 8

$x=1\frac{2}{3}$

Step-by-step explanation:

0 = (x - 8)(3x - 5)

(x - 8)(3x - 5) = 0

x(3x - 5) - 8(3x - 5) = 0

3x² - 5x - 8(3x - 5) = 0

3x² - 5x - 24x + 40 = 0

3x² - 29x + 40 = 0

$x=\frac{-b±\sqrt{b^{2}-4ac } }{2a}$

Ignore the A before the ±. It wouldn't let me type it correctly.

3x² - 29x + 40 = 0

a = 3

b = - 29

c = 40

$x=\frac{-(-29)±\sqrt{(-29)^{2}-4((3)(40)) } }{2(3)}$

$x=\frac{-(-29)±\sqrt{841-4((3)(40)) } }{2(3)}$

$x=\frac{29±\sqrt{841-480} }{2(3)}$

$x=\frac{29±\sqrt{361} }{2(3)}$

$x=\frac{29±19 }{2(3)}$

$x=\frac{29±19 }{6}$

Two separate equations

$x=\frac{29+19 }{6}$

$x=\frac{48 }{6}$

x = 8

$x=\frac{29-19 }{6}$

$x=\frac{10 }{6}$

$x=\frac{5 }{3}$

$x=1\frac{2}{3}$
