Answer:x = (39/2)

Step-by-step explanation:Radical Equation entered :     √2x-3 = 6Step by step solution :STEP 1:Isolate the square root on the left hand side      Radical already isolated      √2x-3 = 6STEP 2:Eliminate the radical on the left hand side      Raise both sides to the second power     (√2x-3)2 = (6)2     After squaring      2x-3 = 36STEP 3:Solve the linear equation      Rearranged equation      2x  -39 = 0     Add  39  to both sides      2x  = 39     Divide both sides by 2     A possible solution is :     x = (39/2)STEP 4:Check that the solution is correct      Original equation     √2x-3 = 6     Plug in (39/2) for  x       √2•(39/2)-3 = 6      Simplify      √36 = 6      Solution checks !!     Solution is:       x = (39/2)

This is a System Of Equations and I'd like it to get solved by the Elimination or Substitution Method.x+2y=83x+5y=8
Sonbull [250]

Answer:

x=133 y=-25

Step-by-step explanation:

I'll do both ways for you. So let's start with Substitution:

With the sub method, you have to set both equations equal to each other by setting them equal to the same variable. Since there is no coefficient in front of both x's in both equations, that variable will be easiest to solve for.

x + 2y = 83    &    x + 5y = 8

Solve for x.

x = 83 - 2y     &    x = 8 - 5y

Once you have solved for x, set each equation equal to one another and solve for y now.

83 - 2y = 8 - 5y

Isolate all variables to one side:

83 = 8 - 3y

Now subtract the 8 to fully isolate the y variable:

75 = -3y

Divide by -3:

-25 = y   Now that you have your first variable, plug it into one of the original equations and solve for x.

x + 2(-25) = 83

x - 50 = 83

x = 133

Now for the Elimination method. For this method you need to get rid of a variable by either subtracting/adding each equation together. Again, since you can subtract and x from both equations, you will be left with only the y variable to solve:

Put each equation on top of one another and subtract:

  x + 2y = 83

- (x + 5y = 8)

The x's will cancel out:

(x - x) + (2y - 5y) = (83 - 8)

Simplify:

-3y = 75

Solve for y

y = -25

Then, plug y = -25 into one of the original equations:

x + 5(-25) = 8

Solve for x:

x - 125 = 8

x = 133

Hope this helps!

What is 1/4×2/5÷1/3 as a fraction<br> please help
Vikki [24]

Answer:

3/10

Step-by-step explanation:

Please give brainliest!

hope this helps :)

the first step is to multiply 1/4 and 2/5

1/4 times 2/5 = 2/20

you figure this out by multiplying the numerators and denominators.

next, we solve 2/20 ÷ 1/3

we do this by taking the reciprocal of 1/3, which is 3/1, and then multiplying the fractions

2/20 times 3/1 = 6/20

6/20 = 3/10
