Answer:
(−4, −8), because the point satisfies both equations
Step-by-step explanation:
Line A
y = x - 4
Line B
y = 3x + 4
If we equate those 2 equations
x - 4 = 3x + 4
2x = -8
x = -4
y = -8
Answer:
9
Step-by-step explanation:
I used tan but there's probably an easier way to do this but 4*tan(20)=8.94 then round it up to 9
18bags
Look if 1=3 2=9 3= 18 so he uses 18 bags!
B) 196 cubic cm or something like that... First you multiply 7x5x14=490... then you divide 490/5 because you're working in fifths and get 98... the white is only two-fifths so you multiply 98 times 2 and get 196
