Answer:
3 4/15
Step-by-step explanation:
Perimiter is width plus width plus length plus length and they give you the width but since there is two widths you have to add the widths then subtract that from 11 1/5 and the answer from that gets divided by two.
If wrong let me know and i will try again
Answer:
26/52
Step-by-step explanation:
I believe this is correct
S=cost per student ticket
a=cost per adult ticket
value=(students vlue)+(adults value)
student value=(cost per student) times number of students
adult value=(cost per adult) times number of adults
you sell 8 adult and 6 students and that is a value of 126
8a+6s=126
friend sell12 adult and 13 student and get 209
12a+13s=209
so we have
8a+6s=126 and
12a+13s=209
it might help to simplify the first equaiton by dividing by 2
4a+3s=63
we have
4a+3s=63
12a+13s=209
multiply first equaton by -3
-12a-9s=-189
add to secont equaiton
12a+13s=209
<u>-12a-9s=-189 +
</u>0a+4s=20<u> </u>
4s=20
divide 4
s=5
each student ticket costs $5.00
Step-by-step explanation:
Simply Equation 1
R. H. S
6x^2 -x +3-2x^2-8
==> 6x^2-2x^2 -x +3-8
==> 4x^2-x-5 .....(1)
Simply equation 2
L. H. S
4x^2+2x-5-3x
==> 4x^2 +2x-3x-5
==> 4x^2-x-5 ....(2)
Since here, RHS = LHS
both eqn (1) = eqn(2)
hence they are equal.
Answer:Associative property of addition: Changing the grouping of addends does not change the sum. For example, ( 2 + 3 ) + 4 = 2 + ( 3 + 4 ) (2 + 3) + 4 = 2 + (3 + 4) (2+3)+4=2+(3+4
