I will do it step by step
(3xy^-5)^3= 27x^3y^-15
(x^-2y^2)^-4= x^8y-8
So the fraction is (27x^3y^-15)/ x^8 y^8= 27 x^-5y^-7
and the whole thing to power of -2 equals to x^10y^14/ 729
answer is A

A(b-c)=d solve for c
Romashka-Z-Leto [24]
A(b-c)=d
Ab-Ac=d
-Ab    -Ab from both sides
-Ac=d-Ab
divide -A 
c=d-Ab over -A and the -A's should cancel so it should be c=db <span />

Jon hikes 12 mi at a constant rate of 3 mi/h.<br><br><br><br> How many hours does he hike?
Radda [10]

Because Jon is walking at a constant rate, the equation will be simple division. Because Jon walks 3 miles per hour, if you divide 12 miles by 3 miles per hour (12 mi / 3 mph), the miles in the equation cancel and you are left with 12 / 3 hours. 12 / 3 = 4, so Jon is hiking for 4 hours.

What value of x is in the solution set of 2(3x – 1) ≥ 4x – 6?<br><br> –10<br> –5<br> –3<br> –1
givi [52]

Answer: -1

Step-by-step explanation:

Given by your question

2(3x-1)≥4x-6

Distributive property to take off the parentheses

2×3x-2×1≥4x-6

6x-2≥4x-6

Subtract 4x on both sides (Subtractive property of equality)

6x-2-4x≥4x-6-4x

2x-2≥-6

Add 2 on both sides (Addition property of equality)

2x-2+2≥-6+2

2x≥-4

Divide 2 on both sides (Division property of equality)

2/2 x≥-4/2

x≥-2

----------------------------------------------------------------------------

Looking at the options you've provided.

-10 INCORRECT, it is not greater or equal to -2

-5 INCORRECT, it is not greater or equal to -2

-3 INCORRECT, it is not greater or equal to -2

-1 CORRECT, it is greater than -2

Hope this helps!! :)
