45 + 4 makes 49 if that counts
Answer:
21/20
Step-by-step explanation:
That question is impossible because we don’t know what we are trying to solve for it has to be x or y in this scenario it can’t be both we need one to find the other
Well, 217 miles ÷ 62 MPH is 3.5.
so it took the train 3.5 hours.
check it: 62 MPH x 3.5 hours, it went 217 miles
Step-by-step explanation:
3x + 2y = 9
- (3x + y = 6)
=> y = 3.
Therefore 3x + (3) = 6, 3x = 3, x = 1.
The solutions are x = 1 and y = 3.
