Answer:

b = 7

Step-by-step explanation:

3(b−4) + 5b = 44

3b - 12 + 5b = 44

8b = 44 + 12

8b = 56

b = 56/8

b = 7

Answer:

<h2>b = 7</h2>

Step-by-step explanation:

3(b-4)+5b=44\qquad\text{use the distributive property}\\\\3b+(3)(-4)+5b=44\\\\3b-12+5b=44\qquad\text{add 12 to both sides}\\\\3b+5b=44+12\\\\8b=56\qquad\text{divide both sides by 8}\\\\b=7

If P(A or B) =3/4, P(B) = 1/3, and P(A and B) = 1/6, find P(A)
Sloan [31]

Answer:

Step-by-step explanation:

P(A∪B)=3/4

P(B)=1/3

P(A∩B)=1/6

P(A∪B)=P(A)+P(B)-P(A∩B)

\frac{3}{4}=P(A)+\frac{1}{3}-\frac{1}{6}\\P(A)=\frac{3}{4}-\frac{1}{3}+\frac{1}{6}=\frac{9-4+2}{12}=\frac{7}{12}

How do i solve this?<br> 2+4x=2(2x+1)
IgorC [24]

Answer:

Infinitely many solutions (or 2=2 which isnt related)

Step-by-step explanation:

2+4x=4x+2

Distribute the 2 to the numbers inside.

Secondly, Minus the 4x on the right side and also minus the 4x on the right side.

You would end up with 0x.

The answer would be 2=2, but the real answer would be "infinitely many solutions."

If your teacher thinks this is wrong, I don't know what else. I could be wrong but really, I don't care.

A translation along the vector (-2 , 7 ) maps point P to point Q. The coordinates of point Q are (4, -1 ) What are the coordinat
Artist 52 [7]
<span>A translation is simply a "moving" when it comes to a point. In this case, by adding (-2, 7) to the point P, we will find point Q. That is, x-2 gives Q's x-coordinate of 4 and y+7 gives Q's y-coordinate of -1. To start, x-2 = 4 gives an x of -6, and y+7 = -1 gives a y of -8. So, the original point P was located at (-6,-8).</span>

Where r is the radius of the cylinder and h is the height of the cylinder.
AnnyKZ [126]
<h3>Given:-</h3>
  • radius = 7 inches
  • height = 9 inches

\\  \\

<h3>To find:</h3>
  • Surface area of cylinder

\\  \\

we know:-

\bigstar \boxed{ \rm Surface \: Area \: of \: Cylinder=2\pi rh+2\pi {r}^{2} }

\\  \\

So:-

⇢SA of cylinder=2πrh+2πr²

\\

⇢SA of cylinder = 2πr(h+r)

\\

⇢SA of cylinder = 2 × π × 7(7 + 9)

\\

⇢SA of cylinder = 2 × π × 7 (16)

\\

⇢SA of cylinder = 2 × π × 112

\\

⇢SA of cylinder = 2 × 112 × π

\\

⇢SA of cylinder = 224π inches ²

\\
