Answer:
D) no solution.
Step-by-step explanation:
4(x + 1) ≤ 4x + 3
First, distribute 4 to all terms within the parenthesis:
4(x + 1) = 4(x) + 4(1) = 4x + 4
4x + 4 ≤ 4x + 3
Isolate the variable, x. Treat the "≤" as an equal sign, what you do to one side, you do to the other. Subtract 4x and 4 from both sides:
4x (-4x) + 4 (-4) ≤ 4x (-4x) + 3 (-4)
4x - 4x ≤ 3 - 4
0 ≤ -1
Since x was eliminated from the inequality, and you need the x for the inequality, your answer is D) no solution.

Answer: <u>₹759407.56</u>
Step-by-step explanation: Total No. of passengers = 400
1 Coach = 50 passengers
∴Total No. of coaches= 400/50=8 coaches.
Cost for each passenger= £23
∴Total cost for 400 passengers= 400x£23
= £9200 ( 1£=82.5443 ₹) ∴ Total cost for passengers = <u>₹759407.56</u>
Money spent per mile= 70p
∴Money spent for 200 miles= 200x70p=14000p
(1₹=100p) thus, 14000p=<u>₹140</u>
<u><em>Total profit</em></u>= <em>Money from the passengers- Money spent for fuel</em>
∴<u>₹759407.56- ₹140= ₹7,59,407.56</u>

Midpoint formula

Let S denote the midpoint of R and T
The rate a computer works is 1/time. Working together, you add the rates.
Let new computer be x, old computer be y.
x = y - 7

Rounded to nearest tenth gives:
x = 23 hours
