Answer:

Step-by-step explanation:

In 5 days there was a 75 point loss

In 1 day there was a loss of x (which would be the average per day)

5/75 = 1/x Cross multiply

5x = 75 * 1

5x = 75 Divide by 5

5x/5 = 75/5 Do the division

x = 15

The average loss was 15 points a day.

Answer:

15 points

Step-by-step explanation:

Divide the 75 points by the five days to find the average points lost per day.

75 points / 5 days = 15 points per day

4x-30=180 your missing the 180 part because it’s a straight line. so do 4x-30=180. subtract 30 from 180, then when you get that answer divide it by four

The congruence theorem that can be used to prove △LON ≅ △LMN is SSS. ASA. SAS. HL.

Zinaida [17]

Answer:

The correct option is SSS (Side-Side-Side) Theorem

Step-by-step explanation:

The question is incomplete because the diagrams of ΔLON and ΔLMN are not given. I have attached the diagram of both triangles below for better understanding of the question.

Consider the diagram attached below. We have to find the congruence theorem which can be used to prove that ΔLON ≅ ΔLMN

We can see in the diagram that both triangle have a common side that is LN. It means 1 side of both triangles is congruent because LN≅LN

Consider the sides ON and MN. Both side have a single bar on them, which means that it is given that both of these side are congruent. Hence ON≅MN

Consider the sides LO and LM. Both side have a double bars on them, which means that it is given that both of these side are also congruent. Hence LO≅LM

SSS theorem states that if all sides of the triangles are congruent, then the triangles themselves are also congruent, which is the same case in this question
