(1/4)^-2 - (5^0 x 2) x 1^-1 =
(4/1)^2 - (1 x 2) x 1 = 16-2 = 14
If you raise something to the power of -2, swap numerator and denominator and remove the minus.
So (1/4)^-2 = 4^2 = 16
Also 1^-1 is just 1, not -1.
The answer is 40
you just times 23 by the number of photocopies you need with is 20
so 23x20 which is 460
500-460 is 40
Answer:
Hence after solving the given equation we get <em>x = 13/20.</em>
Step-by-step explanation:
<em>Given:</em>
<em>-3 x + 0.1 + 10 x = x + 4</em>
<em>-3 x + 10 x - x = 4 - 0.1</em>
<em>6 x = 3.9</em>
<em> x =
</em>
<em>x =
</em>
<em>x =
</em>
since the equation on the left can be rewritten :
to be 5n-10 then both sides of the equation are equal
so any real number will work
