Answer:
x ∈ (-∞,-3)∪(0.5,∞)
Step-by-step explanation:
2x^2+6x-x-3>0
2x(x+3)-1(x+3)>0
(2x-1)(x+3)>0
x ∈ (-∞,-3)∪(0.5,∞)
For this you divide the total spent by the total number of pizzas...
16.50/ 3 = $5.50 per pizza.
Area = (1/2) * 4 * 5 = 10 cm²
<span>100% of $X plus 100% of $Y equals $1000
4% of $X plus 6% of $Y equals $58
To solve that clear the second equation of decimals by
multiplying through by 100:
Solve that by either substitution or by elimination:
X = $100 at 4% and $900 at 6%</span>
Answer: $16.50
Step-by-step explanation:
