–2.5p – 20 = 9p + 37.5

Mathematics

Sever21 [200]3 years ago

Answer:

The answer is p = -5

Step-by-step explanation:

-2.5p - 20 = 9p + 37.5

(move constants to one side by adding 20 to both sides)

-2.5p = 9p + 57.5

(move all terms with the "p" variable to one side by subtracting 9 from both sides)

-11.5p = 57.5

(divide both sides by -11.5 to isolate the variable)

p = -5

Answer:

p = - 5

Step-by-step explanation:

–2.5p – 20 = 9p + 37.5

combine like terms:

- 2.5p - 9p = 37.5 + 20

simplify:

- 11.5p = 57.5

p = 57.5 / -11.5

p = - 5

K/13 = 0.6/0.5 what does that equal
photoshop1234 [79]
\frac{k}{13} = \frac{0.6}{0.5} equals k = 15.6

First,
simplify \frac{0.6}{0.5} to 1.2. Your problem should look like: \frac{k}{13} = 1.2
Second, multiply both sides by 13. Your problem should look like: k = 15.6, which is the answer.

Indicate the equation of the given line in standard form.
Lorico [155]
We have that
<span>triangle ABC
where
A(-5, 5), B(1, 1), and C(3, 4) are the vertices

using a graph tool
see the attached figure

the hypotenuse is the segment AC

find the equation of the line AC
</span>A(-5, 5) C(3, 4) 
<span>
step 1
find the slope m
m=(y2-y1)/(x2-x1)-----> m=</span>(4-5)/(3+5)-----> m=-1/8

step 2
with C(3,4) and m=-1/8
find the equation of a line
y-y1=m*(x-x1)-----> y-4=(-1/8)*(x-3)----> y=(-1/8)*x+(3/8)+4
y=(-1/8)*x+(3/8)+4----> multiply by 8----> 8y=-x+3+32
8y=-x+35
the standard form is Ax+By=C
so
x+8y=35
A=1
B=8
C=35

the answer is
x+8y=35

How do you solve for the central area of a polygon?
ycow [4]
Getting the central area of a polygon is not possible. Probably the question refers to the central angle. In a a regular polygon, getting the central angle is that you need to use the formula.

Central Angle of a polygon = 360 degrees / number of sides of a polygon.
Why 360 degrees? Because, a circle has a total of 360 degrees. And a circle is a polygon with no sides.
