15 is at least the quotient of a number and 6 increased by 3

crimeas [40]

Answer:

The number is $x\geq 72$

Step-by-step explanation:

Given:

Quotient $\geq$ 15

Let the number be $x$

The quotient is 15 of a number and 6 which is increaase by 3

Hence forming the inequality expression from the question given we get;

$\frac{x}{6}+3\geq 15$

Now Solving the above equation we get,

$\frac{x}{6}+3\geq 15\\\\\frac{x}{6}\geq 15-3\\\\\frac{x}{6}\geq 12\\\\x\geq 12\times6\\x\geq 72$

Hence the number is $x\geq 72$

A steamer going downstream traveled the distance between two ports in 3 hours. The return trip took 3 hours 40 minutes. Find the

lapo4ka [179]

Answer:

1.8 mph

Step-by-step explanation:

Speed of the steamer in still water is 18 mph.

Speed of the current = x mph.

1. The steamer going downstream traveled the distance between two ports in 3 hours. Traveling downstream the current "helps" the steamer, then the speed is 18 + x mph.

The distance traveled downstream = 3(18 + x) miles.

2. The steamer going upstream traveled the distance between two ports in 3 hours 40 minutes that is $3\frac{2}{3}$ hours. Traveling upstream the current "interferes" the steamer, then the speed is 18 - x mph.
