Hello there.

<span>Question: What is 2c+7=21 please help

Answer: Solve the equation:
Subtract 7 from both sides:
21 - 7 = 14
2c = 14.
Divide both sides by 2:
14/2 = 7
c = 7.

alex buys a home for $276,400. his home is predicted to increase in value 3.5% each year. What is the predicted value of alex's
Katarina [22]
276400(0.035) = $9674 the equivalent value in dollar for every increase in the house then multiplied by 25. $9674*(25) = $241850 + the current value of Alex's home. $276400+ $241850 = $518250 that would be the value of Alex's home in 25  years. The percentage is (518250-276400)/ 276400 =0.875 *100 = 87.5 % increase in value. I hope this would help.
