Answer:

They are in AP then common difference of successive no. is same

Step-by-step explanation:

3d+4 -(2d-1) = 2d-1(2d+1)

=> 3d+4-2d+1 = 2d-1-2d -1

=> d+5 = -2

=> d = -2-5

=> d = -7

Hence the value of d is -7

I need help solving for X<br>The answer choices are <br>-9<br>10<br>-11<br>9​
Andreas93 [3]

Answer:

<em>x = -11</em>

Step-by-step explanation:

<u>Equations</u>

The image shows a right triangle with angles 70°, 90°, and x+31.

The sum of the internal angles of a triangle is 180°, thus:

70 + 90 + x + 31 = 180

Simplifying:

191 + x = 180

Subtracting 191:

x = 180 - 191

x = -11

djyliett [7]

Answer:

D. 56%

Step-by-step explanation:

For the fractions we will do:

\frac{wanted.outcome}{possible.outcomes}

      It depends on if he puts the first name back in, but I am going to asume Mr. Rosart does not, <em>so we will subtract one from the boys for the second pull</em>.

[Wanted over possible] \frac{14}{25}

[Dividing] 14 / 25 = 0.56

[Making a percent] .56 * 100 = 56%

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

Okay.This is a question just for points.And the question is what is {(94 x 3)+ (86 /2)- (3)}?
JulijaS [17]
94 * 3 = 282
86/2  = 43
Therefore this turns into 282 + 43 - 3 = 282 + 40 = 322
