Answer: 6 people ordered for the lobster dinner.
2 people ordered for the steak dinner.
Step-by-step explanation:
Let x represent the number of people that ordered the lobster dinner.
Let y represent the number of people that ordered the steak dinner.
A family of 8 went out to dinner. This means that
x + y = 8
Each person either ordered the lobster dinner, which costs $25, or the steak dinner which cost $20. The total cost of all the meals is $190. This means that
25x + 20y = 190 - - - - - - - - - -- -1
Substituting x = 8 - y into equation 1, it becomes
25(8 - y) + 20y = 190
200 - 25y + 20y = 190
- 25y + 20y = 190 - 200
- 5y = - 10
y = - 10/ - 5
y = 2
x = 8 - y = 8 - 2
x = 6
The answer is x = 51 okay bro
This question is ultimately asking you to factor 3x² - 9x - 30, which you can do by finding factors of 30 that, when one is multiplied by 3 due to the 3x², makes -9. These factors are 5 and 6, with 5 being multiplied by 3 so you get 15 and 6. Because you have -9, the 5 must be negative, which means the 6 is positive, so you get your final answer as:
(3x + 6)(x - 5)
I hope this helps!
