if the given point satisfies this equation then it would be its solution
(-1)=2(5)-11
-1=10-1
-1=-1
lHS=RHS
Hence (/,-1) is the solution of y=2x-11
Answer:
Percy used 77 liters to wash
Step-by-step explanation:
This question can be solved using a rule of three.
Each minute of washing costs 7 liters.
She washed for 11 minutes.
So
1 minute - 7 liters
11 minutes - x liters
x = 7*11 = 77
Percy used 77 liters to wash
Answer:
117,000
Step-by-step explanation:
156000÷100x25
=39000
Then
156000-39000
=$117,000
Answer:
C
Step-by-step explanation:
Calculate the values of both r and s, that is
= 7 ( multiply both sides by 2 )
5 + r = 14 ( subtract 5 from both sides )
r = 9
and
= 3 ( multiply both sides by 2 )
3 + s = 6 ( subtract 3 from both sides )
s = 3
Hence
= 
= 6 → C
