The least common multiple is 32
y = ( 3 * x ) - 2.
This is because the card costs for 3 $ and should be multiplied by the number of total cards she buys in that particular day. So 3 * x.
Now as she has got a 2$ off coupon, whatever the total is she gets 2 dollars off on that price. So we will subtract 2 at that time. FInally all this summed up would be equal to y.
Answer:
B. -7j-k-1
Step-by-step explanation:
Simplify:
1. IDENTIFY LIKE TERMS
<em>10k</em>+17-7j-18-<em>11k</em>
- <em>10k and -11k are like terms since they have the same variable.</em>
- 17 and -18 are like terms since they are regular numbers.
2. COMBINE LIKE TERMS
-7j-<em>k</em>-1
14gallons=380miles
14/380=<span>0.03684210526gallons/mile
</span>
418*<span>0.03684210526=15.4gallons
</span>
or you could cross multiply
14gallons=380miles
x gallons=418miles
380x=5852
divide both sides by 380
x=15.4 gallons
