Hey there! Thanks for asking your question here on Brainly!

You can find the rule to this sequence fairly easily. Take the last number (37) and subtract the second-to-last number (25) from it. That gives you 12. Next, take 25 and subtract 18 from it, which equals 7. Lastly, take 18 and subtract 11 from it, which equals 7. Therefore, the sequence is arithmetic.

The rule would be +7, +7, +12

Finding the rule involves taking one number and subtracting the number before it in order to find the difference between the two numbers, or how the sequence changes.

Hope this helps!! If there's anything else I can help you with, please let me know! :)

$\bf{Hello!}$

The answer is 140°

Because we can use exterior angle property here

Exterior angle property : It states that exterior angle is the sum of two opposite interior angles

y = 120 + 20 = 140°

Identify the terms of the expression 9a+4b-18

madreJ [45]

Hey there!

We may ask. What exactly is a term anyways.

Well, a term is a single number, a variable, or a number and a variable that would have to be multiply together. This is what a term would be.

Therefore, as we look above, we see the following equation.

9a+4b-18

18 is a term

4b is a term

9a is a term

This whole thing, would be called an expression, as this is expression something. Perhaps the amount of students who ate ice-cream at a football game, or something similar.

I hope you found this helpful! :)

You have to take 60 degrees and add it to 90 degrees because that’s how much the box in the corner is worth

Then add those 2 together which is 150 after that’s subtract it by 270 which is 120

Answer: 120 degrees or 120

Divide. Write the quotient in lowest terms. 1/4 ÷ 1 1/8

natta225 [31]

Answer:2/11

Step-by-step explanation:

A fraction is in simplest form when the top and bottom cannot be any smaller

Firstly start by getting the common factors between 1 and 4 in 1/4 and 11 and 8 in 11/8. The common factor is 1 in 1/4 and 1 in 11/8. 1÷1/4÷1= 1/4. 11÷1/8÷1 = 11/8.

1/4÷ 11/8 =2/11.
