Answer:
where x denotes number of small rooms and y denotes number of large rooms
Step-by-step explanation:
Given: Small rooms can hold 3 people, and large rooms can hold 4 people.
Number of small rooms is twice the number of large rooms.
Small rooms and large rooms altogether can accommodate 70 guests.
To find: system of equations that could be used to determine the number of small rooms reserved and the number of large rooms reserved
Solution:
Let x denotes number of small rooms and y denotes number of large rooms.
As number of small rooms is twice the number of large rooms,

As small rooms and large rooms altogether can accommodate 70 guests such that small rooms can hold 3 people, and large rooms can hold 4 people,

Divide the number of ice-cream bars into the number of people. Example: say you have 20 ice cream bars and 10 people you divide 20/10 and get 2 ice cream bars per person. Hope this helped.
Step-by-step explanation:
Factor 98n2−200
98n2−200
=2(7n+10)(7n−10)
Answer:
2(7n+10)(7n−10)
Solving inequalities is just like solving equations, except you have < or > instead of =, so:
7x + 18 > -3
- 18
7x > -21
÷ 7
x > -3
So your answer is A, x > -3. I hope this helps!
