Step-by-step explanation:
The line above the letter means "complement". If X is a set, the the complement of X (denoted by X with a line above it) is the set of all things not in X...If X is a set, then the complement of X (denoted by X with a line above it) is the set of all things not in X.
Sorry if it was complicated
X-the number
16 + 2x = -24 |subtract 16 from both sides
2x = -40 |divide both sides by 2
<u>x = -20</u>
Answer: <em>The number is -24</em>
7.5 - 3.2 = 4.3 + 4 = 8.3^3 = 571.787 ÷ 2 = 285.8935 rounded to 285.9
Answer:
2x -3y =1 and 3x-2y= 4 has
Step-by-step explanation:
The pair of linear equations 2x-3y=1 and 3x-2y=4 has one unique solution. , then it has a unique solution other wise not. Since , , it means the pair of linear equations has only one unique solution. Hence, the pair of linear equations 2x-3y=1 and 3x-2y=4 has only one unique solution.
a1/a2= 2/3
b1/b2= 3/-2 (-) cancle so it remains
c1 / c2 = 1/4
a1/a2 = b1/b2 not equal to c1/c2 as no solution
Answer:
no, depends on what the ball costs but no because its .25 (meaning cents) not 25.00 (meaning dollars)
