Answer:
x=24/7
Step-by-step explanation:
3(x+2)+4(x-5)=10
3x+6+4(x-5)=10
3x+6+4x-20=10
7x+6-20=10
7x-14=20
7x=24
x=24/7
Answer:
25:15

Answer: 137.17 miles
Step-by-step explanation: To know the driven miles, we will have to find the extra money paid divided by the unitary price of each driven mile.
Extra money=$29.46-$25=$4.46
Miles=
=31.17 miles
However, this price per mile is only charged after 100 miles, therefore we will have to sum the extra miles driven and the 100 miles for the basis
Total=100 miles+31.17 miles=137.17
Answer:
No positive value of n
Step-by-step explanation:
we have to find out for how many positive values of n are both
our-digit integers
Let us consider first cube
we get 4digit lowest number is 1000 and it has cube root as 10.
Thus 10 is the least integer which satisfies four digits for cube.
The highest integer is 9999 and it has cube root as 21.54
or 21 the highest integer.
Considering 3^n we get,
3^10 is having 5 digits and also 3^21
Thus there is no positive value of n which satisfy that both n cube and 3 power n are four digits.
