Suppose you receive $100 for a graduation present, and you deposit it in a savings account. then each week thereafter, you add $5 to the account but no interest is earned. the amount in the account is a function of the number of weeks that have passed. use your equation to find when you will have $310 in the account.

If 5x - 2 = -12, then x = a) -50 b) -4.4 c) -2.8 d) -2

Suppose that a customer is purchasing a car. he conducts an experiment in which he puts 10 gallons of gas in the car and drives it until it runs out of gas. he conducts this experiment 15 times on each car and records the number of miles driven. full data set car 1 238238 216216 205205 212212 240240 274274 297297 252252 260260 247247 257257 243243 296296 243243 290290 car 2 245245 204204 215215 209209 251251 165165 221221 295295 172172 287287 268268 305305 320320 260260 297297 describe each data set, that is determine the shape, center, and spread. sample mean for car 1 x overbar equalsx=216216 mi / 10 gal (type an integer or decimal rounded to one decimal place as needed.) sample mean for car 2 x overbar equalsx=209209 mi / 10 gal (type an integer or decimal rounded to one decimal place as needed.)

Find the value of x. also give me an explanation so i can complete it to other questions as well, : )
