Answer:
G
Step-by-step explanation:
Red marble probably currently: 12/32 = 3/8
Guess and check (using the multiple choice answers):
F: 12 + 13 / 32 + 13 = 25/45 = 5/6; does not equal 3/5
G: 12 + 18 / 32 + 18 = 30/50 = 3/5; does equal 3/5
H: 12 + 28 / 32 + 28 = 40/60 = 2/3; does not equal 3/5
J: 12 + 32 / 32 + 32 = 44/64 = 11/16; does not equal 3/5
K: 12 + 40 / 32 + 40 = 52/72 = 13/18; does not equal 3/5
Answer: x =5.5
x+3=8.5
subtract “-3” from both sides
x = 5.5
Answer:
x=129 degrees
Step-by-step explanation:
Answer: y=-2x-3 = x=-1/2y+-3/2
5x = -4+ y = x=1/5y+-4/5
proof:
y=-2x-3 -- Step 1: Flip the equation.
−2x−3=y
Step 2: Add 3 to both sides.
−2x−3+3=y+3
−2x=y+3
Step 3: Divide both sides by -2.
−2x/-2=y+3/-2
5x = -4+ y -- Step 1: Divide both sides by 5.
5x/5=y-4/5
Well first you have to leave x by itself this will result in x2=-10 now to get the x completly by itself square root both sides this will leave you with x= square root of 10 and that would be your final answer because you cant simplify it no more
Hope this helped
