Answer:
woah ill look at it and come back when i find the answer
Step-by-step explanation:
Answer:
together they have 60
Step-by-step explanation:
B= number of balloons billy has
A =adams balloons
Adam had 30 less balloons than Billy
A = B-30
After Billy gave 5 balloons to Adam, the number of Adam's balloons was half of the number of Billy's balloons.
1/2(B-5) = A+5
1/2 (B-5)-5 =A
set the two equations equal A = B-30 equal to 1/2(B-5)-5 = A
B-30 = 1/2(B-5)-5
add 5 to each side
B-30 + 5 = 1/2 (B-5)
B - 25 = 1/2 ( B-5)
multiply by 2
2(B-25) = 2* 1/2 (B-5)
distribute
2B-50 = B-5
subtract B
2B-50 -B =B-B -5
B-50 = -5
add 50
B-50+50 = -5+50
B = 45
Now we need to find out A
A = B-30
A = 45-30
A = 15
Billy has 45
Adam has 15
together they have 45+15
together they have 60
12385=X[(((1-(1+0.069/12)^(-12*5))/(0.069/12)]
Solve for x
X=244.65
Answer:
x = 
Step-by-step explanation:
Data provided:
ln(x) − ln(y) = 2a
Now,
The using the following properties of log function,
we have
log(A) - log(B) = 
and,
ln(a) = b is equivalent to a = 
(here e is exponential )
ln(e) = 1
therefore,
the above equation transforms as:
= 2a
taking anti-ln both sides,
we get
= 
or
x =
