Answer:

x = the amount of money Jane had before she took out any

x - 135 = 650

x = 785

Step-by-step explanation:

Let x = the amount of money Jane had before she took out any

Set up the equation

x - 135 = 650

To solve the equation, we must add 135 on both sides to cancel the -135 on the left side of the equal sign.

x - 135 = 650

x = 785

What is to 3v=v+6? I just in chance this is for homework.

Answers

3v=v+6

Subtract v from both sides

3v-v = v+6-v

2v= 6

Now divide both sides by 2

2v/2=6/2

v= 3

I hope that's help:0

Lets check if the answer is good

all you need to do is to replace v by 3

3v=v+6

3(3)=3+6

9=9

To graph this on a coordinate plane, you have to go left 10 and down to -3. On 3,2, you go right 3 then up 2.

Step-by-step explanation:

2^x+5 = 3^1-x use logarithms to solve the exponential equation. round answer to 3 decimal places.

Answers

$2^(x+5)=3^(1-x)\ \ \ \ \ /log_2()\n\nlog_22^(x+5)=log_23^(1-x)\n\nx+5=(1-x)log_23\n\nx+5=log_23-xlog_23\n\nx+xlog_23=log_23-5\n\nx(1+log_23)=log_23-5\ \ \ \ /:(1+log_23)$

$x=(log_23-5)/(1+log_23)\n-------------\nlog_23\approx1.5849625\n----------------\nx\approx(1.5849625-5)/(1+1.5849625)\approx-1.321$

2^x+5 = 3^1-x
take log on both sides
(x+5)log2=(1-x)log3
0.3010(x+5) = (1-x)0.4771
0.3010x + 1.5050 = 0.4771 - 0.4771x
0.7781x= -1.0279
x=-1.320

help ! Find the volume of cylinder with a diameter of 8 inches and a height that is three times the radius. Use 3.14 for pi and round your answer to the nearest hundredth.( only numerical answers ! )

Answers

diameter(d)=8 in.
radius(r)= d/2= 4 in.
height(h)= 3r = 3(4) = 12 in.

Volume= $\pi$ r ² h
=(3.14)(4)²(12)
=(3.14)(16)(12)
=602.88 in.

Therefore, the volume of the cylinder is 602.88 in.
