Derrick rode 21 total km.
You can find this by adding the 3 distances together and multiplying by 3. Also remember to watch the units as 500m = .5km.
Do you have to make an equation? if so, the answer would be n - 8
Step-by-step explanation:
Case 1 : |x| > a, => x > a or x < -a
Case 2 : |x| < a, => -a < x < a
Since this question follows Case 1, we will have an "or" inequality.
Brand a: per fork is 0.06 cents.
Brand b: per fork is 0.05
Choose brand B!
Can't give you the "expression" but here's the rest....
(b) 60+20=80; 150+10=160 answer: Tom (1st month pay) and 60+(20x12)=300;
150+(10x12)=270 answer: Edward.
(c) 60+(20x9)=240; 150+(10x9)=240 answer: 9th month.
(d) the better deal for a gym membership would be the membership to the Superfit Gym. The reason is because by the end of the 12 month year, Edward will pay $270.00 instead of $300.00 that Platinum Gym will charge.
