C. g=-5 is the correct answer
In a proportion there are letters assigned to represent various numbers. a, b, c, and d.
a, b, c, and d are 4 non-zero rational numbers that are terms of proportion.
a/b = c/d or a:b = c:d
a and d are the end terms or known as the extremes.
b and c are the middle terms or known as the means.
With this information, we can gather that the extremes of the following proportion are 3 and 60.
3/15 = 12/60 ; a/b = c/d
a = 3 ; b = 15 ; c = 12 ; d = 60
3 and 60 are the extremes
15 and 12 are the means
For the answer to the question above,
The simple interest formula is I = P * r * t
P is the principal (2,000)
r is the interest rate (7% or 0.07)
t is the time (5)
2000 * 0.07 * 5 = 700
$700.00 is the interest
Joe has to pay $700.00 in interest.
I hope this helps
Answer:
7
Step-by-step explanation:
The following equation can be derived from the question
Let x = unknown number
5 + 2x = 3x - 2
collect like terms
5 + 2 = 3x - 2x
x = 7
