Un decimal que es 1/10 de 3,0 es 0,3
Answer:
1/5
Step-by-step explanation:
To avoid ambiguity, your negative exponent -3/2 should be enclosed in brackets or parentheses, as should your exponent 1/3:
( 25^[-3/2] )^ (1/3)
This is equivalent to:
(√25)^(-3)· (1/3), or
5^(-1), or 1/5.
<span>A) -x+y=4
B) 6x+y= -8
Multiplying "A" by -1
A) x -y = -4 then adding it to B
B) 6x + y = -8
7x =-12
x = -12/7 = </span><span>-1.7142857143
y = 4 + x = </span><span><span><span>2.2857142857
