P(a ∪ b) = p(a) + p(b) - p(a ∩ b)
p(a ∩ b) = p(a) + p(b) - p(a ∪ b)
p(a ∩ b) = 1/3 + 2/5 - 3/5
p(a ∩ b) = 2/15
It is 546.4583333333333, which would simplify to 546.46 if to the hundredths place or 546.5 to the tens place
You would recieve $37.95 a year then multiply that by 7 years to get $265.65
2y=10x-14
5x-y=7
Divide both sides by 2 in the 1st equation
y=5x-7
Now substitute is to 2nd equation
5x-5x+7=7
0=0
Therefore there is no solution or it is inconsistent
parallelogram , opposite sides are equal
so
PR = QS
and
PQ = RS
4x - 1 = 3x + 7
x = 8
PQ = 4(8) - 1 = 32 -1 = 31
Given P = 74 cm
74 - 2(31) = 12
PR = QS = 12/2 = 6
Answer
QS = 6 cm
