Answer:
-3(3+4x)
Step-by-step explanation:
The cost of an adult ticket is $15.50 and the cost of a child ticket is $8.50
Proof:
Set up a system of equations calling Adults a and Children c
2a+3c= $56.50 (equation 1)
4c+a= $49.50 (equation 2)
a= -4c+49.50 (i subtracted 4c to both sides) (label equation 3)
sub equation 3 into equation 1
2(-4c+49.50)+3c= 56.50
-8c+99+3c=56.50
-5c+99=56.50
-99 -99
-5c = -42.50
c= -42.50/ -5
c= 8.50
sub c=8.50 into equation 3 to find adult price
a= -4(8.5)+49.50
a= 15.50
Therefore Child Cost = $8.50 and Adult Cost= $15.50
When multiplying fractions, multiply straight across:
(-3/7) (6/5) =
(-3 * 6) / (7*5)=
-18/35
The answer is B.
Answer:
Right of -7 and left of -1
-7 is in the left and -4 is in the right
-7<4
-4 in the left and -1 in the right
-4<-1
Step-by-step explanation:
if your doing the same question as i did then thats the answer
2.2 can be represented like
2 2/10 or 2 1/5
Also, you can say it is 22/10 or 11/5
I hope this helps!
