Amira wants to ride her bicycle 48 miles this week. She has already ridden 18 miles. If she rides for 5 more days, write and solve an equation that can be used to determine x, the average number of miles she would have to ride each day to meet her goal.

PLEASE WRITE AN EQUATION

Answer is 48=5x + 18 equation

Solved X = 6

Step by step

Using y intercept form y=mx + b

Y is the total goal of 48 miles
M is rate, here it is 5 days
X is the unknown miles
B is the y intercept or set amount/starting point, which is the 18 already ridden

So

48 = 5x + 18

Solve

Subtract 18 from both sides to isolate X

48 -18 = 5x +18 - 18

30 = 5x

Divide both sides by 5 to solve for x

30/5 = 5/5 x

6 = x

Now we check our work

48 = 5x + 18

48 = (5) (6) + 18

48 = 30 + 18

48 = 48

Problem solved!
