Answer:
100 children
150 adults
Step-by-step explanation:
c- children
a- adults
---------------
we get equations as per question:
- 1.5c+4a= 750
- c+a= 250 ⇒ a= 250- c
- 1.5c +4(250-c)= 750 ⇒
- 1.5c- 4c+1000=750 ⇒
- 2.5 c= 250 ⇒
- c= 100
- a= 250-100 ⇒
- a= 150
Children 100, adults 150
I think it is always true. I am not sure but I hope I'm right
Answer:

Step-by-step explanation:
Answer:
The first one:
−8x4−14x2−3
Step-by-step explanation:
(-4•2-1)(2•2+3)
-4•2 = -8
-8 - 1 = -9
(-9)(2•2+3)
2•2 = 4
4+3 = 7
(-9)(7) = -63
Now we find the one that equals -63:
-8•4-14•2-3
(-8•4)-14•2-3
-32-14•2-3
-32-(14•2)-3
-32-28-3
(-32-28)-3
-60-3
-60-3 = -63
BAM! THE ANSWER!
Answer:
(-1, 4)
Step-by-step explanation:
Point B is 5 units below point A, and point E is 5 units above point D: AB = ED. This means that BC will be equal to EF. B and C are 7 units apart, so 7 units left from E is (-1, 4).
Hope this helps!
