Answer:
-16/45
Step-by-step explanation:
8/15 x (-2/3)
multiplying a positive and a negative equals a negative
-8/15 x 2/3
multiply the fractions
-16/45
Answer:
10 x -6y = -76
-56 - 10x - y = -76
10x - 6y = -76 (-56) - (-76) = 20
-10 x -y = -20
10x - 6y = -76
-10x -y =-20
10x cancels
76 + 20 = 96
-7y = - 96
divide both sides by -7
y = 96/7
substitute into -10x - y = - 20
- 10x - 96/7 = - 20
96/7 is a fraction btw
= -10 x = - 20 + 96/7
-20 + 96/7
-10 x = -44/7
divide by - 10
x = 22/ 35 ( a fraction)
(x,y) = (22/ 35) ( 96/7)
Answer:
option 1
Step-by-step explanation:
cube root of 125 = 5
cube root of 27 = 3
5+3 = 8
now take x^10 =cube root of x^(3+3+3+1)
cube root of x^10 = x^(1+1+1)+*cube root of x
cube root of y^13 = cube root of y^(3+3+3+3+1)
= y^4*cube root of y
so answer is opt 1
Answer: C
Step-by-step explanation: All the the numbers can be multiplied evenly into 15a^2b^2
>5a^2b *3b = 15a^2b^2
>15ab^2 * a =15a^2b^2
