In order to solve this we must first,
Subtract both sides of the equation by 10,
y-10=1/2x
Now we have to multiply both sides by 2 so that only x is left.
2y-20=x
Therefore, x=2y-20
Answer:
x = 
Step-by-step explanation:
Using the rule of exponents
= 
Note that 8 = 2³ and 2 =
, then
=
, that is
= 
Since the bases on both sides are equal, equate the exponents
3x = 1 ( divide both sides by 3 )
x = 
Answer: 110
Step-by-step explanation:
11x20=220 220\2=110
0.824.....Apex if answer changed not my fault but kinda helpful
question a is 80
question b 20 (is what I could find but not completely sure)
