Hi there! I can help you.
Rate: To find the rate, let’s divide interest earned by the principal. When you do, you get 0.15. Multiply by 100 to get 15 and divide by 3 to get 5. The simple interest rate is 5%.
New balance: All you have to do is add the principal and he new balance. When you do, you get 517.5. The new balance is $517.50.
7x +16 < -5(4 - 5x)....given
7x + 16 < -20 + 25x....distributive property
16 < -20 + 18x ... subtraction property
16 + 20 < 18x.....addition property
36 < 18x
36/18 < x.....division property
2 < x
2x² + 6x - 3 + 2x³ - 3x + 2
Combine like terms
2x³ + 2x² + 6x - 3x - 3 + 2
Final answer:
2x³ + 2x² + 3x - 1
The value is the tens place
I don't know, I just need points
