Answer:
the unknown angle is 88°
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the opposite interior angles. Therefore, in the tall triangle, 60 + 40 = 100, meaning the bottom left angle in the small triangle is 100-64=36. And b/c angle sum of a triangle is 180°, 180-36-56=88°

Step-by-step explanation:
honestly not 100% sure but it seems the most specific
Answer:
The difference of 8 times a number r and 12 is solved for a number r and is given by 
Step-by-step explanation:
Given problem is the difference of 8 times a number r and 12
It can be written as
To simplify the above expression :
8r-12
( using addition property of equality )
(using division property of equality )
Therefore
Therefore the difference of 8 times a number r and 12 is solved for a number r and is given by
The second one because the denominator is smaller meaning the second term is smaller and the first is bigger 2/3 > 2/4
Answer:
You have to translate these sentences into expressions. I am not going to solve all of these because if I explain one/two problems to you, you'll get the hang of it. Seven more than three times a number: 7+3x; Five times a number decreased by six: 5x-6
Step-by-step explanation:
Why? We don't know what number that is, so we can put any variable like (x, y, z, a, b, etc.). Three times a number is simply that number times 3. In this case we would input: 3*x, or 3x. 7 more than that number is 3x+7. Five times a number decreased by six: 5x-6 . Remember: it is simply 5*x which simplifies to 5x. Decreased is take away, so take away 6, and get 5x-6
Key words: Quotient: the result after dividing two/or more numbers; Product: the result after multiplying two/ or more numbers; Decreased: take away (Example: x decreased by 7=x-7)
I hope you understand!! It is very simple after you start to get the hang of it!!
