100-20 round the last numbers so they have a 0 at the end so 4 or under is 0 and 5 or higher is 10 so 100 - 20 is 80
The unknown angles are in a ratio of 7 to 13.
Let 7x represent the smaller measure.Then, 13x represents the larger measure.
7x + 13x + 140 = 180
20x + 140 = 180
20x = 40
x = 2
7x = 7 * 2 = 14
13x = 13 * 2 = 26
The measures are 14 degree and 26 degrees.
Answer:
y = -2
Step-by-step explanation:
y - 2 = -4
add 2 to both sides
y - 2 + 2 = -4 + 2
y = -2
The answer is C. Identify property of addition
Answer:
4
Step-by-step explanation:
The greatest common factor (GCF) is the highest factor of two numbers...
4 (4) = 16
3 (4) = 12
4 is a factor of both 12 and 16. It is also the greatest factor of the two numbers. For example, 2 is also a factor of 12 and 16. However, it is not the greatest number... 4 is.
