Answer:
A
Step-by-step explanation:
a and d look similar but I'm quite sure it's a
120 times because 300 divided by 25
17 = 3(4x - 5)
<em><u>Distributive property.</u></em>
17 = 12x - 15
<em><u>Add 15 to both sides.</u></em>
32 = 12x
<em><u>Divide both sides by 12.</u></em>
x = 2.67. (This is your answer.)
Let me know if you have any questions.
For the first one, to find x, you are going to take that entire side which would equal to 180 and solve. 2x+20+55=180 would then go down to 2x+65=180 once you add the 20 and 55. Then subtract 65 to both sides and divide your final answer 115/2 which is x=57.5. For the second one it’s 4x-2+21=180, then you will subtract 2 from 21 and get 19. After you would subtract 19 by 180 and divide 4 by each side, getting x=40.25 as your final answer.
