Answer:
(-1, -1)
Step-by-step explanation:
Answer:
length times width times height
Step-by-step explanation:
width is height by the way
so 20×10×9 gives you 1800
1800 petrol can hold on Meters
7 & 8/10 or 78/10 ( which is the same thing)
I’m guessing the question is written as (-6)^-1x=27^-1
to get rid of a negative exponent, you use the reciprocal of the number.
so (-6)^-1 would be 1/-6
27^-1 would be 1/27
rewrite is as
(1/-6)x = 1/27
multiply both sides by reciprocal or 1/-6 to cancel it and make x by itself
it’s would be x = 1/27(-6)
multiply
x = -6/27
simplify
the final answer is x=-2/9
