Answer: There will be $ 1687.02 in the account after 7 years.
Step-by-step explanation:
Formula to find the accumulated amount (A) in account on principal amount (P) with rate of interest (r) in 't' years is given by :-

As per given, P = $1400
r= 2.7% = 0.027
t= 7 years
Then,

Hence, there will be $ 1687.02 in the account after 7 years.
Given :
a restaurant customer left a $1.95 as a tip.
The tax = 5%
the tip was 15% of the after-tax cost
So, the information that not needed is the tax
Let the total bill = x
so, 15% of x = 1.95

so, the total bill = $13
Answer:
Step-by-step explanation:
hello :
the system is : x+ y =4 ...(*)
2x - y = -1...(**)
add(*) and (**) : 3x=3 so : x=1
put this value into (*) : 1+y=4 so : y=3
one solution : (1 , 3)
Answer:
(A) put the 7 in front of the log
log 6 (6)^7 = x
7 * log 6 (6) = x
7 * 1 = x
x = 7
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4. GCF is often used to find common denominators
