The easiest way I know is to multiply the divisor by different numbers to see how many times it will go into the dividend. multiplying 486 by 2 or three and seeing which one gets closest.
Y=3x+19
You add 3x to each side. Because your trying to get y by its self like y=mx+b.
(8,5) because (6,5) is distance 2 from (6,3). So (8,5) will distance 2 from (8,3)
Answer:
$25 a lamp
Step-by-step explanation:
First divide $10,000 by 500 lamps to find how much one of them cost
That is $20 a lamp so then multiply .25 *20 or 1/4 *20
you get 5 than add 20 +5=25
