Rational numbers are numbers that can be written as a fraction and ?

answer is below

Step-by-step explanation:

i don't know if you have answer choices for this question, but rational functions are any number that can be written as a fraction or decimal that has a repeating pattern or is finite.

ex:

1/2, 4.5, 1/3, 2.6666..., -23, -1.91919...

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
