Angle FBC is 67
you would figure this out using supplementary angles and the Z pattern
Step-by-step explanation:
substitute the value of y in terms of x
-2x - 3(6x-11)= -7
-2x - 18x+ 33=-7
-20x= -40
x = -40/-20
x= 2
substitute x=2 in first equation
y= 12-11
y= 1
Answer:
A. 2a² / 5b
Step-by-step explanation:
12a³b² / 30ab³
cancel the common factor = 6
= 2a³b² / 5ab³
cancel the common factor = a
= 2a²b² / 5b³
apply exponent rule, so
= 2a² / 5b³ ⁻ ²
subtract 3 - 2 = 1
= 2a² / 5b
