Jamal factored it completely.
in Jennifer's answer, 3x+3 has a common factor of 3 which can be factored to become 3(x+1) which is what Jamal did.
8x + 3× + 9x = 180
20x = 180
x = 180/20
x = 9
The smallest angle is: 3×9 = 27 degrees
Note: 180 degrees is the sum of angles in a triangle
Answer:172.5
Step-by-step explanation:Xoxo
Answer:
b. The variable will always be the letter x (false)
Step-by-step explanation:
Variables can be any letter or symbol. The letter x is often used as a variable, but that is not the only choice. Many formulas, for example, make use of variables that have letters reminding you what they stand for.
For example, the formula ...
A = 1/2(b1 +b2)h
uses the variables A, b1, b2, and h to represent area, base-1, base-2, and height, respectively. The letter x is not used at all.
Answer -4/27
-1/9 x 4/3 will give you -4/27
