Answer with explanation:
Let speed of Mike =x miles an hour
Then, Speed of Erica=(x+3) miles an hour
Total Distance between two cities which needs to get traveled by Mike and Erica=462 mile
Speed of Mike=63 miles an hour
Speed of Erica=63+3=66 miles an hour
X=6.75
3+x=5x-24 Add 24 on both sides
27+x=5x Subtract 1x on both sides
27=4x Divide 4 on both sides
6.75=x You Can double check by plugging in x
Answer:
7x -1 is correct after combining like terms
Step-by-step explanation:
6+8x-7-x
To simplify algebraic expression we combine like terms
In the given expression
-x or -1x are same
8x and -1x are like terms
6 and -7 are also like terms
8x-1x= 7x
6 - 7 = -1
So 7x -1 is correct after combining like terms
