6. Write the inequality using interval notation for the graph.
makkiz [27]

Answer:

C

Step-by-step explanation:

C is the correct answer because it represents exactly what the graph shows with the bold lines.

As you can see in the graph, there is no interception between 7 and 12. Therfore, the answer can't be B(because it represents the area between the two numbers).

A isn't the correct answer either because it represents a dot, which is obviously not the case here since there is no dot.

I can't explain why C isn't the right answer, but I hope that explanation that I gave is enough for you to understand ;)

(If you have any questions about the way I solved it, don't hesitate to ask me in the comments, and if you find my answer helpful - consider marking it Brainliest ÷) )

17. Oscar, Lily and Jack collect souvenir coins. Oscar has 44 more coins than Lily and 48 more coins than Jack, Oscar has 6 more
Sladkaya [172]

Answer:

166 marbles

Step-by-step explanation:

O - 44 = L

O - 48 = J

O - 6 = L + J

I want to isolate O here

O = 44 + L

Plug it in

44 + L - 6 = L + J

38 + L = L + J

38 = J

Now we know that Jack has 38.

O - 48 = J

O - 48 = 38

O = 86

Now we know Oscar has 86.

O - 44 = L

86 - 44 = L

42 = L

Lily has 42.

38 + 86 + 42 = .....166

They have 166 coins altogether - Also Happy New Year!!! :D
