## MeganDarling 3 years ago Eghh I'm so bad at Algebra >.< Help? The length of a rectangle is 9.7 cm more than 4 times the width. If the perimeter of the rectangle is 91.4 cm, what are its dimensions? Or with this one? A rental car agency charges a flat fee of \$110.00 plus \$46.00 per day to rent a certain car. Another agency charges a fee of \$70.00 plus \$54.00 per day to rent the same car. Using a graphing calculator, find the number of days for which the costs are the same. Round your answer to the nearest whole day.

Any sort of help would be really appreciated

second one: solve \[110+46x=70+54x\] for \(x\)

5. satellite73

hello you should get \[100=70+8x\] \[40=8x\] \[5=x\]
