Answer:
y = 2
Step-by-step explanation:
I will solve this problem, using the elimination method.
-2(5x - 3y) = -11
-10x + 6y = 22
2x - 6y = -14
Subtract and divide for x
-8x = 8
x = -1
Input -1 into the equations
2(-1) - 6y = -14
-6y - 2 = -14
-6y = -12
y = 2
Thanks!
Answer:
x=75
Step-by-step explanation:
A( I mean angle)+B+C+D=360°
A=C
B=D
2A+2D=360°
A+D=180°
30°+x+x=180°
2x=150°
x=75
Answer:
no solutions
Step-by-step explanation:
6n - 6n - 12 = 14 - 2 = 12 ( add 12 to both sides )
0 = 24 ← not possible
this indicates the equation has no solution
Yo sup??
the angle is in 3rd quadrant.
we can say that
sin(90+150)
=sin(180+60)
=-sin(60)
=-3^(1/2)/2
Hence the correct answer is option A
Hope this helps
Answer:
Step-by-step explanation:
p=10(q-3r)/r
Cross multiply
pr = 10(q-3r)
pr = 10q - 30r
Pr + 30r = 10q
r(p + 30) = 10q
r = 10q/(p + 30)
