Answer:
2700ft^3
Step-by-step explanation:
X≥8 shows the inequality for at least 8
A. About $80 ; 53 round down to 50, 67 round up to 70
B. $53 + $67 = 120
200 - 120 = 80
Exactly $80
To eliminate a cariable in a system of equations, we multiply the variable by a factor that will make both coefficients of the variable to be equal.
Thus, we multiply the coefficient of y in the second equation by a factor that will make it equal to the coefficient of y in the first equation. i.e. multiply 1/2 by a factor that makes it equal to 3/4. and the factor is 3/2.
Therefore, the third option is the correct answer.
