A) 11

Step-by-step explaination:

CE = 2x - 2

CE = CD + DE

Hence it can be said that,

2x - 2 = x + 9

2x - x = 9 + 2

x = 11

the angles of a triangle are in the ratio 3:4:5. what is the degree measure of the smallest angle of the triangle?

Alik [6]

A triangle interior angles add up to 180

so we have 3:4:5
the ratio of the angles
3+4+5=12
therefor 180=12 units
divide by 12
15=1 unit
subsitute
find the smallest unit

A bike rental company rented out 6 bikes in its first month. The number of bikes it rented tripled each month.

Alexeev081 [22]

Hi there!

The total number of bikes rented is 2,184

If you plug in the correct numbers into the formula

$a \dfrac{1- r^{n} }{1-r}$

Then you get

$6 \dfrac{1- 3^{6} }{1-3}$

And when the fraction is simplified it looks like this

$6 \dfrac{-728}{-2}$

Once this is in simplified form you take the 6 and put it over 1 like so

$\dfrac{6}{1} * \dfrac{-728}{-2}$

Then you find the prime factors of 6 and factor the -2 like so

$\dfrac{3*2}{1} * \dfrac{-728}{-1*2}$

Once this is done cancel out the 2

$\dfrac{3}{1} * \dfrac{-728}{-1}$

Then multiply -728 by 3

$\dfrac{-2184}{-1}$

Then divide to get 2184

3х + Зу = 8<br> 2х - у = 5<br> what is the solution?????

patriot [66]

Answer:

x = 23/9

y = 1/9

Step-by-step explanation:

2x - y + y - 5 = 5 + y - 5

2x - 5 = y

3x + 3(2x - 5) = 8

3x + 6x - 15 = 8

9x/9 = 23/9

x = 23/9

2x - 5 = y

2(23/9) - 5 = y

46/9 - 5 = y

1/9 = y
