A = b+5
ab = 3300
(b+5)b = 3300
b² +5b -3300 = 0 (quadratic formula)
b=55
a=60 (by first relation)
Answer:
10^3
Step-by-step explanation:

If Jamie's age is represented as x and given that Ana is the same age as Jamie then, Ana's age can also be represented by x. The sum of their ages is equal to,
Sum of their ages = x + x
Simplifying,
Sum of their ages = 2x
Answer:
-30
Step-by-step explanation:
first you should complete the equition of bracket
1-3/4+(-121/4)
= 1-3/4+(-30.25)

=0.25+(-30.25)
=-30
hence the right answer is -30 :)
