Answer:
1. x< 3
2. x>12
have a great day :)
Step-by-step explanation:
Answer:
1/3
Step-by-step explanation:
the formula of common ratio is given as
a1= 27 ,a2=9
r= 9/27
r= 1/3
Answer:
a. max. 25c. min.13c
b. 2:00
Step-by-step explanation:
Assuming the sum of the opposite angle would be 180. We can easily calculate for x and ultimately solve for the angle of B. We do as follows
B + D = 180
3x-12 + x = 180
4x - 12 = 180
4x = 192
x = 48 degrees
Therefore angle B would have a measurement of 132 degrees. Hope this helps.
2x +4y =10x-3y =12
2x +4y =12 -----eq. 1
10x-3y =12 -------eq.2
2x =12 -4y [using eq. 1]
x = (12-4y)/ 2
= 6 -2y
Now, substitute the value of x in eq. 2
10 (6-2y)-3y =10
60 -20y -3y =10
-23 y = 10 -60
y = -50 / -23
y = 50/23
Now, substitute this value of y in any equations given above
10 x-3 (50/23) =12
10x - (150/23)= 12
x= 426/230
