Answer:
Step-by-step explanation:
<u>Step 1</u>
- s = 3 terms x 6 years, s = 18 years
<u>Step 2</u>
- h = 30 years - 18 years, h = 12 years
<u>Step 3</u>
- t = 12 years ÷ 2 years, t = 6 terms
To simplify a fraction (reduce it to lowest terms), you divide
the numerator and denominator both by their greatest common
factor. (That's why you learn 'greatest common factor' before
you learn to simplify fractions.)
The greatest common factor of 36 and 80 is 4 .
Divide the top and bottom of 36/80 by 4, and you'll have the
fraction in lowest terms.
ANSWER IS LAST CHOICE 256/81
You can take the reciprocal of the fraction and drop the negative sign in the exponent. Then:
(-4/3)^4 = (-4)^4 / 3^4 = 256/81
Answer:
According to the graph about <u>5 percent</u> of households in Africa owns a computer in 2008.
2013 about 1/3 of all households in <u>Asia</u> had a computer.
The number of households with a computer is <u>increasing</u> in all regions overtime.
Answer:
yes
Step-by-step explanation:
because we are simply "adding" 2 negative numbers.
-8n + -7 = -7 + -8n
as long as we flip the terms around with their signs, the commutative principle of addition applies.
what we CANNOT do is e.g.
8n - 7 = 7 - 8n
THERE would be a problem.
but again, by also keeping the signs with the terms, it is all OK.
so, yes, we could also do
8n - 7 = -7 + 8n
that is true again.
