Which value could replace x in the table? O 30-gtg
O 3(30 -9)
O 30-g(3)
O 30-g+3

Pls help ;(

0 3(30-9) and 0 30-g(3)

Step-by-step explanation: 0 3(30-9)=(3)(21)=63

and 0 30-g(3)=-3g+30=(3-g+10)

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
