The expression for the money deposited in the bank is 500 + 40m and it will take 7 months to get the required amount.
The compound interest is a form of interest where the rate of interest is applied on the amount obtained after every interval of time.
(A) The balance of Raj's account is given as $500.
And, the money deposited every month is $40.
Suppose, the number of months be m.
Then, the following expression can be written for money in account as,
500 + 40m.
(B) The equation for the given case can be written as,
500 + 40m = 780
⇒ 40m = 280
⇒ m = 7
Hence, the required expression is 500 + 40m number of months required is 7.

Answer:
-733.13
Step-by-step explanation:
Take absolute value of each number
(add absolute value bars to show what you're doing)
-734.8 = 734.8
-1.67 = 1.67
Then do regular subtraction
734.8 - 1.67 = 733.13
Then put back the negative symbol in front and you have your answer
-733.13

Step-by-step explanation:
b(3x-2x+c) = 9 - 6x+15
Answer:
b=3
c=5
Step-by-step explanation:
b(3x^{2}-2x+c) = 9x^{2} - 6x+15
Distribute
3b x^2 -6x +bc = 9x^2 -6x +15
Each term must be equal
3bx^2 = 9x^2
3b = 9
Divide by 3
3b/3 = 9/3
b =3
bc = 15
3c =15
Divide by 3
3c/3 = 15/3
c =5
