Answer:
x = 7
Step-by-step explanation:
First, move the variables and numbers to the opposite sides
-3x = 12 - 33
Then add and subtract
-3x = -21
Divide and multiply
-x = -7
x = 7
Lets test out all the answers
A. 2/3 is about .666 so A is not
B. 3/5 is .75 so B is B also not
C 7/9 is 0.7777 which is still less so C is not
D. 4/5 is about 0.80 and this is more than 0.78 so D is the answer
Step-by-step explanation:
Antoine= 125 cards
Antoine2?= 125+36= 161 cards
Antoine + Antoine2= 125+161= 286 cards
Answer:
discriminant=D=0
Step-by-step explanation:
given, 9x^2-18x+9=0...............(1)
equ (1) divided by 9
x^2-2x+1=0
discriminant=D=b^2-4ac
where, b=-2, a=1, c=1
D=(-2)^2-
D=4-4=0
D=0
hence discriminant=D=0 answer
The correct answer would be ‘B’ because...
A rounds up to 277000
B rounds to 276000
C rounds to 275000
And D rounds to 275000 as well.
