Answer:
7=x
Step-by-step explanation:
multiply 5 and 2x by 2, you'll then have (10+4x)=-4+6x. Then add 4 to both sides and you have (14+4x)=6x. Subtract 4x from both sides and that'll get you 14=2x and you divide 2 from each side to get x by itself so 7 is your answer.

189 is 45% of 420 and 198 is 55% of 360
189 = .45x

420 = x
198 = .55x
/.55 /.55
360 = x
Answer:
x < 12
Step-by-step explanation:
Note that the symbol for:
"less than" is <
"greater than" is >
"less than or equal to" is ≤
"greater than or equal to" is ≥
In this case, the question states that the variable "x" is less than 12. Set the equation: x < 12
x < 12 is your answer.
