Answer:

It would be 4:15

Step-by-step explanation:

You would take 20 and 75 and put them in a ratio that would look like this 20:75, then they are divisable by 5 so you reduce them, when you reduce them you get 4:15

Solve for the roots in simplest form by completing the square <br><br> x^2-12x+20=0
Alex17521 [72]

Answer:

x = 10 or x = 2

Step-by-step explanation:

Solve for x:

x^2 - 12 x + 20 = 0

Hint: | Solve the quadratic equation by completing the square.

Subtract 20 from both sides:

x^2 - 12 x = -20

Hint: | Take one half of the coefficient of x and square it, then add it to both sides.

Add 36 to both sides:

x^2 - 12 x + 36 = 16

Hint: | Factor the left hand side.

Write the left hand side as a square:

(x - 6)^2 = 16

Hint: | Eliminate the exponent on the left hand side.

Take the square root of both sides:

x - 6 = 4 or x - 6 = -4

Hint: | Look at the first equation: Solve for x.

Add 6 to both sides:

x = 10 or x - 6 = -4

Hint: | Look at the second equation: Solve for x.

Add 6 to both sides:

Answer: x = 10 or x = 2

A computer is on sale for 30% off with a sales tax of 10%.what is the final price of the computer if the computer was originally
Fynjy0 [20]
Answer is $924. First you must multiply 1200 by .3 for the sales tax. Giving you 360. You subtract 360 from 1200 giving you 840. Then you multiple 840 by .1 which gives you 84. You then add 84 to 840 giving you $924.

E is the midpoint of AB. If<br> AE = 4x +6 and EB = 10x - 12,<br> what is AB?
zzz [600]

Answer:

36

Step-by-step explanation:

Since E is the midpoint, AE and EB are equal. We can write this as such,

4x+6=10x-12 if we solve from here we get 6x=18. Simplify to get x=3. sub in three for  x in the AE equation, 4(3)+6 and solve. You'd get 18 as your answer. Double that to get the solution since AE= 1/2AB. 18*2= 36

AB=36
