Answer:

g(7) =  \frac{45}{8} \\   \: or \:   \\ 5 \frac{5}{8}

Step-by-step explanation:

We would just apply the 7 in g(7) as all the x

g(x)= 7/8x - 1/2

g(7)= 7/8(7) -1/2

\frac{7}{8}  \times  \frac{7}{1}  =  \frac{49}{8}

Simplify

g(7)= 49/8 -1/2

Multiply -1/2 by 4/4 to get the denominators the same

\frac{49}{8}  -  \frac{4}{8}  =  \frac{45}{8}

answer: g(7)=45/8

(simplified): g(7)=5 5/8

A student walked 100 meters north, then 100 meters west. how many more meters did the student walk compared to their total displ
seraphim [82]

Using Pythagorean theorem, the student walked 53.58 meters more compared to the total displacement from the starting point.

If a student walks 100 meters north, then 100 meters west, then the path he travels resembles the sides of a right triangle (see attached photo).

Using Pythagorean theorem, we can solve for the total displacement from the starting point to the end point.

c^2 = a^2 + b^2

where c is the total displacement from the starting point to the end point

a is the distance he walks up north

b is the distance he walks to the west

c^2 = 100^2 + 100^2

c^2 = 10,000 + 10,000

c^2 = 20,000

c = 141.42 meters

Comparing the total distance the student walked and the total displacement from the starting point to the end point by subtraction.

100 meters + 100 meters - 141.42 meters = 53.58 meters

Finding x :8x + 10 - 5x = 15.​
Misha Larkins [42]

Answer:

Here you go! 8x+10-5x!

Just kidding. here you go. x=1.66

Step-by-step explanation:

you can simplifiy the x´s by making it 3x by subtracting. You can also subract 10 from both sides. That leaves you with 3x=5.

x=1.66
