A rational number that is not an integer can be expressed in decimal form with a non-zero digit after the decimal
(3,52)(7,108)
slope = (108 - 52) / (7 - 3) = 56/4 = 14
y = mx + b
slope(m) = 14
(3,52)...x = 3 and y = 52
sub and find b, the y int (the original amount of cards)
52 = 3(14) + b
52 = 42 + b
52 - 42 = b
10 = b
so ur equation is y = 14x + 10....with x being the number of years and y being the total cards. <== ur equation is y = 14x + 10
He started with 10 cards....and has been adding 14 cards every year.
so after 10 years...
y = 14(10) + 10
y = 140 + 10
y = 150 <== after 10 years, he will have 150 cards
40 times 3/3+5= Niamh’s amount = 40x3/8 = 15 pencils
40 times 5/3+5= Jack’s amount =
40x5/8 = 25 pencils
<span><span>If you would like
to </span>divide 7/24 by 35/38, you can
calculate this using the following steps:<span>
7/24 / 35/38 =
7/24 * 38/35 = (7 * 38) / (24 * 35) = 19/60
<span>The
correct result would be </span>19/60<span>.</span></span></span>
