What is the solution set of negative X equals -8

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

the unknown can NEVER be negative

so you wont see an answer like

-b= 7, -a=98; -k= -9

so,

-x= -8 (change their positions so that the unknown, x, is positive)

x=8

4. A marathon is 42.195 km, how many miles is this

Answers

Answer:

26.2244 mi

Step-by-step explanation:

Step 1: Find conversion

1 mi = 1.609 km

Step 2: Use Dimensional Analysis

$42.195 \hspace{2} km (\frac{1 \hspace{2} mi}{1.609 \hspace{2} km} )$

26.2244 mi

42.195 km = 26.219 miles

I'm giving 50 points and brainliest answer to whoever can answer this... Please show your work so I can try to understand it xD <3

Ok, to solve this first you have to set up your proportion:

9/150=x/230

/ is a fraction

x= the number of vials it will take to treat 230 patients

in order to solve this, you have to cross multiply:

9 x 230= 2070

150 · x= 150x

so you get 150x=2070

then divide 2070 by 150

2070/150= 13.8

so it would take 13.8 vials of medicine to treat 230 patients

Okay, firstly, you want to work out how many people will 1 vial of malaria treat. So, you do this:

150 divided by 9= 16.6

That means for every 1 vial, 16.6 people are treated.

Since the question asks you to find out how many vials are needed if you're required to treat 230 people, you would do this:

230 divided by 16.6= 13.8

That means you need 13.8 vials to treat 230 people.

The coordinates of triangle GBW are G (20, 10) B (-35, 20), and W (5,-10). Is GBW a right triangle? Justify your answer.

Answers

We know from Pythagoras' Theorem, a right angle triangle can be identified by the relationship:

$a^2+b^2=c^2$

Thus, we know if the side lengths of the triangle in question abide by this relation, the triangle is right.

First, we must find the greatest side length.

We know, using the distance formula.

$GB= √((-35-20)^2 +(20-10)^2) =√(3125)$
$BW= √((5+35)^2 +(-10-20)^2) =√(2500)$
$WG= √((20-5)^2 +(10+10)^2) =√(625)$

From this, we know that:
$GB\ \textgreater \ BW\ \textgreater \ WG$
Therefore, GB would be the hypotenuse of the triangle.
Now we substitute the values for the two shorter lengths and the greater length into the pythagorean theorem:
$a^2+b^2=2500+625=3125$
$c^2=3125$
$\therefore LHS=RHS$
Therefore, this triangle is a right angled triangle
