Find the value of x please help me​

Mathematics
1 answer:
scoray [572]3 years ago
5 0

Answer:

x = 25

Step-by-step explanation:

Sun of the exterior angles of a quadrilateral = 360°

Therefore:

x + 40 + 6x + 2x + 20 + 3x = 360

Add like terms

x + 6x + 2x + 3x + 40 + 20 = 360

12x + 60 = 360

12x = 360 - 60

12x = 300

x = 300/12

x = 25

What equation I should use for this problem
Mama L [17]
I'm not completely sure, but this should be exponential growth.
If so, the equation for exponential growth is: y = a(1 + r)^t
If I substitute them with the information you gave me, then is would look like this:
 y = 281.4(1 + 0.02)^t
**t = is the number of years after 2000 (based on your question)**

If Kaylee was 18 and Lylah was 45 how many years younger would Kaylee be??
SVETLANKA909090 [29]
You are trying to find how much younger Kaylee is than Lylah. 

You would subtract her age from Lylah's.

45-18= 27

Kaylee was 27 years younger than Lylah.

I hope this helps!

Drag each expression to show whether it is equivalent to 54x plus 18, 18(3x minus 1), or (6 times 9x) plus (6 times 1)
topjm [15]

The first option is

18(3x-1) = 18\cdot 3x - 18\cdot 1 = 54x-18

The second option is

6\cdot 9x + 6\cdot 1 = 54x + 6

So, neither of them is equivalent to 54x+18
