Answer:
431 reserved tickets, 1356 general tickets
Step-by-step explanation:
4x + 3y = 5792
x + y = 1787
Start with these equations and guess numbers and eventually you'll be right
1000x + 787y =6361 WRONG
700x + 1087y = 6061 WRONG
500 x + 1287y = 5861, close but WRONG
430 x + 1357 y = 5791, very close but WRONG
431 x + 1356y = $5792, CORRECT
431 + 1356 = 1787 tickets sold
Oranges=r
apples=a
12<em>r</em>+7<em>a</em>=5.36
-12<em>r </em> -12<em>r</em>
What you do on one side you do on both sides
12 on the left cancels out
7<em>a</em>=5.36-12<em>r</em>
/7 /7 /7
Divide 7
7 on the left cancels out
5.36/7=0.76....
left with
<em>a</em>=0.76-12<em>r</em>/7
so the apples cost $0.76 each
to get the cost of the oranges (<em>r</em>) you do the same as you did to get the cost of the apples.
Also on the other equation for 8 oranges and 5 apples you might get different answers but you will see that they are close/similar to the same answers as you will get for the last equations.
Answer: 50.0
Step-by-step explanation:
1. Add 45+55=100
2. Divide 100 by 2 =50
3. Add a decimal after 50.0
Not a real number because a negative number is imaginary
Answer:
≈ 78.55 cm
Step-by-step explanation:
Using the ratio of arc (AB) to circumference (C) is equal to the ratio of angle subtended at centre by arc AB to 360°, that is
= 
, that is
= ( cross- multiply )
110C = 8640 ( divide both sides by 110 )
C = 
≈ 78.55 cm ( to 2 dec. places )
