Are the graphs of the lines in the pair parallel? Explain. <br> y = 3/7x+ 11 –3x + 7y = 13
ankoles [38]
Remember that parallel lines have the same slope.

y=3/7x+11 (in slope intercept form already)

-3x+7y=13 (standard form)

Add 3x to both sides, giving you 7y=3x+13, divide by 7 on both sides, giving 


y=3/7x+13/7

Since both equations' slopes' are the same, their graphs will be parallel.

Martha Alison and Scott buy 3.8 pounds of clay Martha used 1 /4 of the clay for a sculpture Scott used 2/5 of the remaining amou
Sever21 [200]

They are left with 0.51 pounds of clay.

Step-by-step explanation:

Given,

Amount of clay bought = 3.8 pounds

Amount used by Martha = \frac{1}{4}\ of\ clay

Amount used by Martha = \frac{1}{4}*3.8=0.95\ pounds

Amount left after Martha's use= Total amount - amount used by Martha

Amount left = 3.8 - 0.95 = 2.85 pounds

Amount used by Scott = \frac{2}{5}\ of\ amount\ left

Amount used by Scott = \frac{2}{5}*2.85=\frac{5.70}{5}

Amount used by Scott = 1.14 pounds

Amount left after Scott's use = Amount left after Martha's - Amount used by Scott

Amount left after Scott's use = 2.85 - 1.14 = 1.71 pounds

Amount used by Alison = 1.2 pounds

Amount left = Amount left after Scott's use - Amount used by Alison

Amount left = 1.71 - 1.2 = 0.51 pounds

They are left with 0.51 pounds of clay.
