Answer:

Hence the simplified answer is 241.

Step-by-step explanation:

Given:

2^8-10-15/3

To Find:

Simplified and correct answer reasoning.

Solution:

Now,

The rule for arithmetic operation is given by,

BODMAS or PODMAS

The each letter is definded as follows:

B=<em>bracket or parentheses </em>

<em>O= order</em>

<em>D=division</em>

<em>M=Multiplication</em>

<em>A= addition</em>

<em>S=subtraction.</em>

So here there is no bracket ,next will be order which 2^8 ,then Division which 15/3 and afterwards subtraction.

So equation is simplified as ;

2^8-10-15/3

=256-10-15/3

=256-10-5        ........<em>..(for same operation perform from left to right side)</em>

=246-5

=241

A line passes through the points (2, –2) and (–6, 2). The point (a, –4) is also on the line. What is the value of a?
Minchanka [31]
First, we need to find the slope:
m=rise/run   OR
m= \frac{y_2-y_1}{x_2-x_1}
m=(2+2)/(-6-2)
m=4/-8
m=-1/2

second we need to find the equation for the line using point-slope form:
y-y_1=m(x-x_1)

y-(-2)=-(1/2)(x-2)
y+2= -\frac{1}{2}x+1
y=- \frac{1}{2}x-1

to find "a" we plug in the given y value and solve for x (in this case x=a):

-4=- \frac{1}{2}x-1
-3=- \frac{1}{2} x
-3(-2)=(-  \frac{1}{2} x)( -2)
6=x

so, a=6 and the point becomes (6,-4)

What is the value of x and the length of segment DE?
aniked [119]

Answer:

x = 6.6; DE = 16.6  

Step-by-step explanation:

Assume the diagram is like the figure below.

1. Calculate the value of x

In a right triangle, the altitude drawn from the right angle to the hypotenuse divides the triangle into two similar triangles.

Thus, ∆CDF ~ ∆FDE, and

\begin{array}{rcl}\dfrac{CD}{DF} &=& \dfrac{FD}{DE}\\\\\dfrac{5}{9} &=& \dfrac{9}{2x + 3}\\\\5(2x + 3) & = &81\\10x + 15 & = & 81\\10x & = & 66\\x & = & \mathbf{6.6}\\\end{array}

2. Calculate the length of DE

DE = 2x + 3 = 2(6.6) + 3 = 13.2 + 3 = 16.2

2x – 5x + 16 = -3(x – 6)
inessss [21]

Answer:

16=18

Step-by-step explanation:

2x-5x+16

-3x+16

-3(x-6)

-3x+18

-3x+16+-3x+18

16=18

-they do not share the same answer

and if you where to keep going

18-16=2

0=2

-so again not equal

hope that helps
