Would it be y = 18t + 18r?
6r+7=13+7r
-6r -6r
7=13+r
-13 -13
-6=r
Hope that helps!
Answer:
550 miles.
Step-by-step explanation:
First, we know that each 1,4 (quarter) of an inch equals 50 miles. and we know that four 1,4s equals one. so, using that information, we have 2 3/4. so the 2 has 8 quarters, and then we have 3 quarters left. so we add the 8 quarter's and the 3 quarter's, to get 11. and since each quarter is equal to 50 miles, we multiply 50 by 11.
