Suppose a group of x people rent a jeep for $80 for a trip to the beach and plan to share the cost equally. if one person in the group decides not to go, each remaining person has to pay an extra $4. which equation could be used to determine how many people are in the group?

Step-by-step explanation:

Given that a group of x people rent a jeep for 80 dollars.

Since they share the amount equally we have

each person share =

When one person in the group decides not to go, each remaining person has to pay an extra 4 dollars.

i.e. now the share borne by each in the group would be

This is 4 dollars more than the original

Hence equation would be

This equation would be used to determine how many people are in the group.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
