Answer:
(-7)∧-1
Step-by-step explanation:
(-7)^3 / (-7)^4
taking each and simplifing it
-7³ = -7 x -7 x -7
(-7)∧4 = -7 x -7 x -7 x -7
(-7)^3 / (-7)^4 = (-7 x -7 x -7 ) / ( -7 x -7 x -7 x -7) = 1/-7
1/-7 ( 1/ means raise to power -1)
1/-7 = (-7)∧-1
When we say "5 is the third part of 15," we do not imply a sequence: the first part, the second part, the third, and so on. When we speak of the third part, that is a different meaning for the word "third." It means each one of three equal parts that together make up the whole
Answer:
24 white marbles, 36 black marbles
Step-by-step explanation:
System of Inequalities:
x + y > 20
2/5y + 3/5x > 20
solve first inequality for 'y':
y > 20 - x
Use substitution to solve for 'x':
2/5(20 - x) + 3/5x > 20
8 - 2/5x + 3/5x > 20
1/5x > 12
x > 60
2/5 of 60 = 24
3/5 of 60 = 36
-2(x-6)-4=2(8-x)-x first perform indicated operations on both sides...
-2x+12=16-2x-x
-2x+12=16-3x add 3x to both sides
x+12=16 subtract 12 from both sides
x=4
