3x+5y=2
9x+11y=14
∣⋅(−3)
−9x−15y=−6
9x+11y=14
add both sides of equations

substitute the value of y to the first equation

x=4
Answer: x=4; y=−2→(4; −2)
okay so you should know that the formula for a triangle is:
A=1/2×b×h
where b is breadth and h is height
A is area
so they already gave the area which is 16.2 and they already gave a side ( doesn't matter if it's b or h in this question)
so we put these into the equation of the area of a triangle
A=1/2×b×h
16.2=1/2 × 6 × h
then you will solve algebraically to get 5.4cm which is you answer
to check if correct you can always put in all numbers in equation and you should get 16.2cm
In this case it's correct ✌
Her chances of getting that should be 2/6
Answer:
how can I help?
Step-by-step explanation:
with what?
0.032 is the interest
since it is half a year, double this one
0.032 x 2 = 0.064
your formula is A = P(1 + (r/n)^nt
P is principle
R is rate
N is number of times
T is time
A = <span>32,675.12(1 + (0.032/2)^2(5)
A = 32675.12(1 + (0.016)^10
A = 32675.12(1.016)^10
A = 32675.12 (1.172)
A = 38295.24064
Your answer is ~38295.24
hope this helps
none of the answers make sense, because you can withdraw a lot more money from your bank account than that, unless you are missing some numbers and stuff</span>
