Tom and Brian are hiking towards each other at the opposite ends of a trail that is 21 miles long. Tom hikes uphill at a speed o

Arturiano [62]

Answer:

3.5 hours

Step-by-step explanation:

Distance = 21 miles

Speed * time

Speed * time = distance

Tom speed = 2 mph

Brian = 4 mph

Let time = t

Brian distance + Tom's distance = total distance

4t + 2t = 21

6t = 21

t = 21 / 6

t = 3.5 hours

Im being timed<br>which number line represents the solution set for the inequality?

Ludmilka [50]

Answer:

The solution is:

$-\frac{1}{2}x\ge \:4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-8]\end{bmatrix}$

The number line graph of the solution is also attached below.

From the graph, it is clear that the 2nd number line represents the solution set for the inequality.

Step-by-step explanation:

Given the inequality

$-\frac{1}{2}x\ge 4$

Let us solve the inequality

$-\frac{1}{2}x\ge 4$

Multiply both sides by -1 (reverse the inequality)

$\left(-\frac{1}{2}x\right)\left(-1\right)\le \:4\left(-1\right)$

Simplify

$\frac{1}{2}x\le \:-4$

Multiply both sides by 2

$2\cdot \frac{1}{2}x\le \:2\left(-4\right)$

Simplify

$x\le \:-8$

Thus, the solution is:

$-\frac{1}{2}x\ge \:4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-8]\end{bmatrix}$

The number line graph of the solution is also attached below.

From the graph, it is clear that the 2nd number line represents the solution set for the inequality.

Subtract 4/5-1/6 and write it in a simplest form

svetlana [45]

$\frac{4}{5}-\frac{1}{6}=\ \ \ \ | making\ common\ denominator\\\\
\frac{24}{30}-\frac{5}{30}=\frac{24-5}{30}=\frac{19}{30}\\\\Solution \ is\ \frac{19}{30}.$

a bookseller prices a particular book by raising its wholesale price 60% and then adding $0.75. what is the wholesale price of t

MissTica

Let's named wholesale price with variable x.

The appropriate equation is

1.6 x + 0.75 = 18.75 => 1.6x = 18.75 - 0.75 => 1.6x = 18 => x= 18/1.6

x= 11.25$ The wholesale price is 11.25$

Good luck!!!!
