\huge\text{$x=\boxed{6}$}

We can solve for the variable x by isolating it on one side of the equals sign.

Start by adding 4 to both sides to cancel out the -4 on the left side of the equation.

\begin{aligned}3x-4+4&=14+4\\3x&=18\end{aligned}

Now divide both sides of the equation by 3 since 3x is the same as 3*x and we want to isolate x, keeping in mind that anything multiplied by 1 is itself.

\begin{aligned}3x&=18\\3*x&=18\\3*x\div3&=18\div3\\x*3\div3&=18\div3\\x*1&=6\\x&=\boxed{6}\end{aligned}

\text {Hello! Let's Solve this Problem!}

\text {\underline {The First Step is to Add 4}}

\text {3x-4+4=14+4}

\text {3x=18}

\text {\underline {The Final Step is to Divide 3}}

\text {3x/3=18/3}

\text {Your Answer Would Be:}

\Huge\boxed {x=6}

\text {Best of Luck!}

Answer:

(arranged from top to bottom)

System #3, where x=6

System #1, where x=4

System #7, where x=3

System #5, where x=2

System #2, where x=1

Step-by-step explanation:

System #1: x=4

2x+y=10\\x-3y=-2

To solve, start by isolating your first equation for y.

2x+y=10\\y=-2x+10

Now, plug this value of y into your second equation.

x-3(-2x+10)=-2\\x+6x-30=-2\\7x=28\\x=4

System #2: x=1

x+2y=5\\2x+y=4

Isolate your second equation for y.

2x+y=4\\y=-2x+4

Plug this value of y into your first equation.

x+2(-2x+4)=5\\x+(-4x)+8=5\\x-4x+8=5\\-3x=-3\\x=1

System #3: x=6

5x+y=33\\x=18-4y

Isolate your first equation for y.

5x+y=33\\y=-5x+33

Plug this value of y into your second equation.

x=18-4(-5x+33)\\x=18+20x-132\\-19x=-114\\x=6

System #4: all real numbers (not included in your diagram)

y=13-2x\\8x+4y=52

Plug your value of y into your second equation.

8x+4(13-2x)=52\\8x+52-8x=52\\0=0

<em>all real numbers are solutions</em>

System #5: x=2

x+3y=5\\6x-y=11

Isolate your second equation for y.

6x-y=11\\-y=-6x+11\\y=6x-11

Plug in your value of y to your first equation.

x+3(6x-11)=5\\x+18x-33=5\\19x=38\\x=2

System #6: no solution (not included in your diagram)

2x+y=10\\-6x-3y=-2

Isolate your first equation for y.

2x+y=10\\y=-2x+10

Plug your value of y into your second equation.

-6x-3(-2x+10)=-2\\-6x+6x-30=-2\\-30=-2

<em>no solution</em>

System #7: x=3

y=10+x\\2x+3y=45

Plug your value of y into your second equation.

2x+3(10+x)=45\\2x+30+3x=45\\5x=15\\x=3

The radius r and height h of a right circular cone are both increasing at a constant rate of 2 cm/h. At what rate in centimeters
Elden [556K]

Answer:

94.2

Step-by-step explanation:

i honestly dont know if this answer is right but i am currently takeing classes in math about Geometry. We was learning about Word problems, that had to do with volume, Area, and perimeter, and learned what radius is, etc..

  • So i thought you take the formula it gives you and use. Since Pie means 3.14 you use that in the formula. V= 1×3.14×2×15 = 94.2
  • you would multiply everything together because every number is close together.
  • the height is 15 cm, thats how you get 15 at the end.
  • next step is to solve the equation in your calculator. and it gives you that number. = 94.2
