The answer is 7
If you cancel 1 with -1 you will only have 3y=21 and 3 x 7 is 21 so y=7
A=2000(1+.05)^4
A=2000(1.05)^4
A= $2,431.01
After 4 years there will be $2,431.01 in the account.
Answer:
56
Step-by-step explanation:
Step-by-step explanation:
Remember that the sum of angles on a straight line are supplementary. (180°)
Therefore 3x + 2 + 6x - 20 = 180.
=> 9x - 18 = 180
=> 9x = 198
=> x = 22.
