Answer:
the exact value of x is 2
Step-by-step explanation:
8⁽¹/⁶⁾ x 2ˣ = 32⁽¹/²⁾
32⁽¹/²⁾ = 2⁵⁽¹/²⁾ = 2⁽⁵/²⁾
8⁽¹/⁶⁾ = 2³⁽¹/⁶⁾ = 2⁽¹/²⁾
8⁽¹/⁶⁾ x 2ˣ = 2⁽¹/²⁾ x 2ˣ = 2⁽¹/²⁾+ˣ = 2⁽¹/²+ˣ⁾
since 8⁽¹/⁶⁾ x 2ˣ = 32⁽¹/²⁾ = 2⁽⁵/²⁾
2⁽¹/²+ˣ⁾ = 2⁽⁵/²⁾
equate the powers
1/2+ x = 5/2
subtract 1/2 from both sides
x = 5/2 - 1/2 = (5-1)/2 = 4/2 = 2
x = 2
Answer:
-4(5x - 9) + 6(2x + 5)
multiplication of:
(-).(-) = +
(-).(+) = -
(+).(-) = -
(+).(+) = +
-4(5x) -4(- 9) + 6(2x + 5)
(-)(+)4(5x) (-)(-)4(9) (+)(+) 6(2x) (+)(+)6( 5)
-20x + 36 + 12x + 30
-20x + 12x + 36 + 30
-8x + 66

Answer:
Step-by-step explanation:
p=10(q-3r)/r
Cross multiply
pr = 10(q-3r)
pr = 10q - 30r
Pr + 30r = 10q
r(p + 30) = 10q
r = 10q/(p + 30)
Answer:
For this case we know that the total distance to travel is 325 mi. And we know that Aretha travels at the following velocity:

Then we can use the following definition:

Where D is the distance and V the velocity. And solving for t we got:

And replacing we got:

So then we can conclude that after 5 hours at this rate Aretha will arrive to home
