Perimeter: 64 cm
Step-by-step explanation:
21 + 21 = 42 cm 11 + 11 = 22 cm
42 + 22 = 64 cm
'a/b' is an integer when 'b' is a factor of 'a'.
Answer:
42 student tickets and 98 adult tickets
Step-by-step explanation:
Let's call the number of student tickets 's' and the number of adult tickets 'a'.
Then, we can write the two equations below:
5s + 8a = 994
a = 2s + 14
Using the value of 'a' from the second equation in the first one, we have:
5s + 8*(2s + 14) = 994
5s + 16s + 112 = 994
21s = 882
s = 42
Now, finding the value of 'a', we have:
a = 2*42 + 14 = 98
Answer:
x = -7
Step-by-step explanation:
Given:
5 – x = 12
Subtract 5 from both sides
5 – x - 5 = 12 - 5
- x = 7
Note: the coefficient of -x is -1
- x = 7
Divide both sides by the coefficient of -x
- x / -1 = 7 / -1
x = -7
Check
5 – x = 12
5 - (-7) = 12
5 + 7 = 12
It is possible to subtract a number from 5 and have more than 5 as your answer when the unknown number is a negative value
