Answer:
d = 7
Step-by-step explanation:
7 times 5 = 35
or
35/5 = 7
39/120 = x / 1800....39 choc. chip to 120 students = x choc. chip to 1800 students
now we cross multiply because this is a proportion
(120)(x) = (39)(1800)
120x = 70200
x = 70200/120
x = 585 <===
or u could do it this way as well...
39 out of 120 picked chocolate chip....
39/120 = 0.325 = 32.5%....so 32.5% chose chocolate chip.
32.5% of 1800 = 0.325(1800) = 585 <==

Answer:
16. Parallelogram
17. x=3, y=9
Step-by-step explanation:
16. You should graph it to get a visual. But using the given points, you can tell that the slopes for the lines AC and BD are the same, thus meaning those lines are parallel. The same for lines AD and BC.
17. 5x+2=17, so x= 3
3y-6=21, so y=9
