D. A ray has one endpoint.
Plug in y=3x+2 into the y in the second equation.
x + 2(3x+2) = 11
x + 6x + 4 = 11
7x + 4 = 11
7x = 7
x = 1
then, plug the x value into x in the first equation.
y = 3(1) + 2
y = 3 +2
y = 5
Answer:
15 because 3 x 5 equals 15

Answer: 72</h3>
Divide the 9 inch side into 9 "1 inch" sub-segments
Divide the 4 inch side into 2 "2 inch" segments
Divide the 12 inch side into 4 "3 inch" segments
So we have 9*2*4 = 18*4 = 72 boxes that can fit.
Answer:
180 grams
Step-by-step explanation:
grams of dark chocolate= 200 % cocoa =60%
Grams of milk chocolate: 200 % cocoa=30%
Amount of cocoa in mixture:
(proportion of milk chocolate+ dark chocolate)
(30% of 200)+60% of 200)
(0.3* 200)+(0.6 *200)
60+120
=180 grams
