3(6-2) = (?*6) - (3*2)
? would be equal to 3
M=sales on monday
t=sales on tuesday
w=sales on wednesay
m=3t
w=(1/2)t
if m=1200
1200=3t
divide both 3 both sides
400=t
sub int other one
w=t/2
w=400/2
w=200
m=1200
t=400
w=200
total is 1200+400+200=1800
the total sales is RM 1800
STEPS TO GET THE CORRECT ANSWER:
First write your question like this:
{ ( [9x] [-31/8] ) - ( [7x] [+13/8] ) }
2: You need to subtract 9x and 7x from (9x-31/8)-(7x+13/8) you get 2x. So now you know that the answer has 2x. Eleminate A) and D).
3: Then need to subtract -31/8 from +13/8. You get -11/2.
Turn -11/2 into a mixed number you will get -5 1/2.
4: Put 2x and -5 1/2 together and you would get 2x-5 1/2
But answer C.) is closest to 2x-5 1/2 so the answer is
ANSWER: C.) 2x-4 1/2
------------------------------------------------------------------
Define x :
------------------------------------------------------------------
Let the number be x.
------------------------------------------------------------------
Construct Equation:
------------------------------------------------------------------
x ÷ (-10) = -30
------------------------------------------------------------------
Multiply for (-10) on both sides:
------------------------------------------------------------------
x = (-30) x (-10) = 300
------------------------------------------------------------------
Answer: x = 300
