Answer: the number of children tickets sold 265
the number of adult tickets sold 77
Step-by-step explanation:
Let x represent the number of children tickets sold.
Let y represent the number of adult tickets sold.
They charge $5 per ticket for a child and $12 per ticket for an adult. They were sold for a total of $2250. This means that
5x + 12y = 2250 - - - - - - - - - -1
The total number of tickets sold is 342. This means that
x + y = 342
Substituting x = 342 - y into equation 1, it becomes
5(342 - y) + 12y = 2250
1710 - 5y + 12y = 2250
- 5y + 12y = 2250 - 1710
7y = 540
y = 540/7 = 77
x = 342 - y = 342 - 77
x = 265
Answer: r = 2
Step-by-step explanation:
Answer:
Step-by-step explanation:
first, do 30-2 to get 28. 7-28 is -21. -21/7 is -3
$1.14 1.40 x 0.8=1.12 1.4+ 1.12=1.52 * 0.25 = 1.14
Easy, it says "for ANY positive integer" so just test any positive integer
remember that n! means times all integers from 1 to that number n
lets try 1
(1+1)!/(1!)-1=
(2!)/(1!)-1=
2/1-1=
2-1=
1
if you don't believe me, try 2
(2+1)!/(2!)-2=
(3!)/(2!)-2=
(6)/(2)-2=
3-2=
1
te answer is 1, B
and number 9
easy, remember the exponential law
(x^m)(x^n)=x^(m+n)
jsut add the exponents
first gropu like bases
(r^2r^2/3)(t^1/2t^-3/2)
add bases
(r^2 and 2/3)(t^-1)=
(r^2∛(r^2))(1/t)=
