6a+8b; when a variable is next to a coefficient then that means they are multiplying each other, we just don't know what a or b is.
Answer:
6 1/12 miles total
Step-by-step explanation:
3 1/4 = 13/4
2 5/6 = 17/6 to ADD fractions, you must have a common denominator
I will use 12 for these
13/4 = 39/12
17/6 = 34 /12
now you can add and simplify 39/12 + 34/12 = 73/12 = 6 1/12 miles
7/2,14/4,21/6,28/8,35/10,42/12,49/14,56/16,63/18,70/20
One solution.
They have different slopes and therefore have one solution.
