I need help asap! Dana is trying to walk 12 miles every week. She walked 3 miles on Monday and 5 miles on Wednesday. How many more miles does she need to walk this week in order to reach her goal?
Write an equation and solve.
A) 8x = 12; Dana needs to walk 1.5 more miles.
B) x + 3 + 5 = 12; Dana needs to walk 4 more miles.
C) x + 12 = 3 + 5; Dana needs to walk 4 more miles.
D) x - 3 + 5 = 12; Dana needs to walk 10 more miles.
