Step-by-step explanation:
BODMAS which means
B- brackets
O- of
D- division
M- multiplication
A- addition
so that means you start with the brackets
(5+2)= 7
then with the division
8 / 2-7
4-7= -3
3 x 22+(-3)
66+(-3)
+ X - = -
<em>66-3=63</em>
140% = 1,4 = 14/10
14/10 * x = 56 |(*10/14)
14/10 * 10/14 * x = 56 * 10/14 14/10 * 10/14 => 1
1 * x = (56*10)/14
x = 560/14

Answer:
C. 5x^2 - 8x + 13
Step-by-step explanation:
Answer:
C) 24 adults
Step-by-step explanation:
Let A be the number of adults and C be the number of children.
If a ticket costs $8 per adult, we can express this as 8A
If a ticket costs $5 per child, we can express this as 5C
Combining the two expressions, we can write 8A+5C=272 as our first equation since the total amount of money collected is $272.
Our second equation would be A+C=40 since there are 40 people.
Now, we can take the second equation and write it as C=40-A so we can substitute the value of C into the first equation as 40-A so we only have to deal with one variable, the amount of adults that went to the theater.
The first equation now becomes 8A+5(40-A)=272 and is much easier to solve:
8A+5(40-A)=272
8A+200-5A=272
3A+200=272
3A=72
A=24
Therefore, there are 24 adults
