Answer:
Step-by-step explanation:
5a. 7 < x
b. 2< 2x
c. 8 > x
d. 3 > x/29
joe = j
christina = c
Aaron = a
j = 3a , c = a-6 total ages is 149
149 = j + c+ a
149 = 3a + a-6 + a
149 = 5a-6
add 6 to both sides
149 + 6 = 5a-6+6
155 = 5a
a = 155/5
a = 31
c = a - 6
c = 31 - 6
c = 25
The answer is:
.
____________________________________________Explanation:____________________________________________We have: " 6⁻¹ * (-2)³ * (-4)⁻² = ? " ;
_______________________________________Note: "6⁻¹ =

=

" .
Note the following property of exponents:
____________________________________ a⁻ˣ =

; {x ≠ 0}.
____________________________________________Note: (-2)³ = (-2)*(-2)*(-2) = 4*(-2) = -8 .
_______________________________________Note: (-4)⁻² =

;
=

;
=

;
____________________________________So; we have:
_____________________________________6⁻¹ * (-2)³ * (-4)⁻² ;
=

;
→ Cancel out the "8" in the "numerator" (to a "1") ; and the "16" in the number (and change to a "2"); since: {"16÷8 = 2" ; and since: "{8÷8=1"} ;
→and we have:

;
=

.
