Step-by-step explanation:
V=-2w+31 over 15
w=-15v+31 over 2
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
Time for the whole journey;
Time=
t=
t= 8 hrs
In driving 275 miles, you take,
t=Distance/speed
t=
t= 5 hours
The remaining traveling time is;
8-5
= 3 hours
Answer:
the car is traveling 60 miles per hour
Step-by-step explanation:
Since it is going 30 miles in half an hour, we just need to double both values to find the speed for an hour
30*2=60
1/2*2=1
60 miles per hour
hope this helps pls give crown <3
