For this case we have to:
x: Let the variable representing the unknown number
We algebraically rewrite the given expression:
Eleven more than four times a number, is represented as:
The number less 7, is represented as:
Thus, the complete expression is:
We subtract x from both sides of the equation:
We subtract 11 from both sides of the equation:
Equal signs are added and the same sign is placed:
We divide by 3 on both sides of the equation:
Answer:
let the number of adult tickets be x and the number of children tickets be y
3x + y = 164...equ(1)
2x + 3y = 174....equ(2)
multiplying equation 1 by 3
9x + 3y = 492
subtracting equation 2 from 1
7x = 318
x = 45.43 dollars
substituting the value of x into the equation
3(45.428) + y = 164
y = 164 - 3(45.428)
∴y = 27.71 dollars
It is just two as you are dividing a negative by and negative turns into a positive
Area =
Area = 22/7 x 10 x 10
Area = 314 in^2
(the answer is option A, its rounded)
