Answer:
The number of problems solved = 2000
Step-by-step explanation:
Let us assume the monthly quota of problems be x
number of problem solved in first week = 25 % of x =
number of problems solved in 2nd week = 110% of (problems solved in 1st week)
=
=
number of problem solved 3rd week= 60% of ( problems solved in 1st and 2nd week)
=
=
=
number of problem solved in 4th week =
now we have
number of problems solved in ll 4 weeks = x
Hence the number of problems solved = 2000
Paralell lines have the same slope
perpendicular lines have slopes that multiply to get -1
neither is niegher
so
y=mx+b
m=slope
x=y+2
minus 2
x-2=y
y=x-2
y=1x-2
slope is 1
y=x+3
y=1x+3
1=1
they are paralell
Hey!
~Set up the equation: -5(x-1)=40
~ Divide 5 on both sides: 40/-5
~ Simplify: x-1=-8
~ We want to get x by itself, so subtract +1 to both sides.
~ Simplify: x = -7
~ Therefore, x = -7.
