Answer:
25
Step-by-step explanation:
A = 70*M
B = 500 + 50*M
Costing the same means equal, so we have the equation:
70M = 500 + 50M
-50M -50M
20M = 500
20M / 20 = 500 / 20
m- 25 months
Answer:
1/2 ^w : decay factor after w weeks
hope this helps
Step-by-step explanation:
You can multiply 6p + m = 9 by -2 so you gonna have -12p - 2m = -18 then you can say : -12p - 2m = -18 ⇒ -8p = -10 ⇒ p = 10/8 ⇒ p = 1.25
4p + 2m = 8
so now you can find the m : 6 * 1.25 + m = 9 ⇒ 7.5 + m = 9 ⇒ m = 9 - 7.5 ⇒ m= 1.5 :)))

Look at the picture.


We know, the sum of the measures of the triangle is equal 180°.
Therefore in ΔBCD we have:

<em>subtract 137 from both sides</em>

Answer: x° = 90°, y° = 43°.
