D. Diving both sides by 4 isolates the variable.
Turn 7/4 into a decimal by dividing it and then multiply from there and you get 1.75. Then you time 5.4 by 1.75 and you get 9.45
You would add them all and then decide them by how many numbers there are witch would be 3.

Answer:
A=61, B=74
Step-by-step explanation:
Because all the angles in a triangle add up to 180:
(2x+4) + (2x-9) + x = 180
If you solve that for x, you will get that x=35. Now you just plug in x to the angles A and B.
X= 2.5
just move the terms collect the terms calculate it, divide both sides !!
