Answer:
Step-by-step explanation:
z=5x-11y
+11y on both sides
z+11y=x
divide by 5 on both sides

Answer:
$4055.28
Step-by-step explanation:
Your formula is A=P(1+rt)
P is the amount of money Lance puts in = 3262.50
R is the interest rate in a decimal = .027
T is the time in years = 9
A=3262.50(1+.027x9)
Use a calculator
A=4055.28
Answer:
about 409.946 Hz
Step-by-step explanation:
The multiplier of frequency is (√(tension multiplier))/(length multiplier), so is ...
(√1.25)/1.2 = (5/12)√5 ≈ 0.931695
So, the longer, tighter string will have the lower frequency of about ...
0.931695×440 Hz ≈ 409.946 Hz
P = $1,100
r = 7.25% = 0.0725
A= P(1+r)^t
⇒ 6600 = 1100(1+0.0725)^t
⇒ 6600/1100 = 1.0725^t
⇒ 1.0725^t = 6
Use log to solve it
log(1.0725^t) = log 6
⇒ t * log 1.0725 = log 6
⇒ t * 0.0303973 = 0.7781512
⇒ t = 0.7781512/0.0303973
⇒ t = 25.599 ≈ 25.60 years
The value of d which will.make this system have the same solution is; d = 21/(3x -1)
First, we must make y, the subject of the formula in each case as follows;
- y = (3x -1)/7. and
- y = 3/d.
In essence, by equating y to y in both equations; we have;
By Cross-product; we have;
