You first combine like terms -1x and -4x to make the equation 21=6-5x then subtract 6 from itself to cancel it out and from 21, 15=5x where x= 3
A polynomial can only have one constant, since the constant is the one number being added or subtracted from the rest of the polynomial, and it is the only number that is not being multiplied by an x value.
Answer:
After 6 days Martha biked 330 miles, while Enrico biked 290 miles.
Step-by-step explanation:
i. Martha bikes 55 miles per day.
So that after 6 days, Martha would have covered;
55 miles x 6 = 330 miles
After 6 days, Martha would have biked 330 miles.
ii. Enrico bikes 145 miles every 3 days.
Then after 6 days, Enrico would have covered;
x 145 miles
= 2 x 145 miles
= 290 miles
After 6 days, Enrico would have biked 290 miles.
After 6 days Martha biked 330 miles, while Enrico biked 290 miles.
