Which value is the solution to the equation 20=y+12 ? ( use substitution to find solutions to equations.)
amm1812

Answer:

8 = y

Step-by-step explanation:

In order to find a solution to an algebraic equation such as this one we simply need to isolate the variable. We do this by applying the opposite operation to each side in order to get rid of the other factors and get the variable alone. Like so...

20 = y + 12   ... we need to subtract 12 from both sides to get rid of the 12 on the right side with the variable y.

20 - 12 = y + 12 - 12

8 = y

Finally, we can see that the value of the variable y is 8

It costs Sally 20 cents to make a cup of lemonade, and she sells each cup for 50 cents. She is using the following identity to c
mote1985 [20]

She would make 3.00 dollars


50(10) - 20(10) = (10)(50 - 20)

500 - 200 = (10 * 30)

300 = 300


(10)(50 - 20) = 30(10)

(10 * 30) = 300

300 = 300

Solve x2 - 8x = 3 by completing the square. Which is the solution set
Simora [160]

Answer:

4\pm\sqrt{19}

Step-by-step explanation:

Move everything to left side

x^{2} -8x -3 =0

Now to solve this square equation we need to find Descriminant

D=b^{2} -4ac=64+12=76

As Descriminant D is greater than 0 then we have 2 solutions which we can calculate by this formula

x_{1,2}=\frac{-b\pm\sqrt{D}}{2a} =\frac{8\pm2\sqrt{19}}{2}=4\pm\sqrt{19}

In the figure below, AB and AD and AC bisects angle A . Solve for x. Then, using that value, find the length of AC.
erik [133]

Answer:

x=12

Step-by-step explanation:

Since AB=BD, they have equal length. 15x+4=2x+160, 13x=156, x=12
