<em>i.e. we simply bring the name of both angles together</em>
First, find the LCD. That is 12.
1/3 = 4/12
1/4 = 3 /12
4/12 + 3/12 + 7/12
THE EQUALITY WITH BOUNDARY IS B
' 125% ' means ' 1.25 '
'of' means 'times'
1.25 times (last year) = $10.50
Divide each side
by 1.25: Last year = ($10.50) / 1.25
= $8.40 .
Answer:
Step-by-step explanation:
LHS a - b = -9 - (-6) = -9 +6 = -3
RHS b-a = -6 - (- 9) = -6 +9 = 3
as LHS not equal to RHS
a-b not equal to b-a
Thus proven
