Answer:

x = 4 y = 2

Step-by-step explanation:

2x + y = 10

2x4 = 8

8 + 2 = 10

2x - y = 6

2x4 = 8

8 - 2 = 6

Answer:

Step-by-step explanation:

2x + y = 10......(1)

2x - y = 6........(2)

Substracting (2) from (1)

2x - 2x + y - (-y) = 10 - 6

y + y = 4

2y = 4

Dividing through by 2

y = 4/2

y = 2

Substitute y = 2 in (2)

2x -y = 6

2x - 2 = 6

Collecting like terms

2x = 6 + 2

2x = 8

Dividing by 2

x = 8/2

x = 4

Counting each visible cube, and multiplying it by 2, he used 112. If you counted them, there would be 56 cubes. You'd multiply by 2 for the non-visible ones.

Explain how you got the answer please
kykrilka [37]
-2x + 12 = 2y

Add 2x on both sides,

12 = 2y + 2x

Divide by 2 on both sides,

6 = y + x -> x + y = 6

The answer is D.

Complete the square x^2-10=16<br><br>​
Hatshy [7]

Answer:

(x - 5)² = 41

Step-by-step explanation:

* Lets revise the completing square form

- the form x² ± bx + c is a completing square if it can be put in the form

 (x ± h)² , where b = 2h and c = h²

# The completing square is x² ± bx + c = (x ± h)²

# Remember c must be positive because it is = h²

* Lets use this form to solve the problem

∵ x² - 10x = 16

- Lets equate 2h by -10

∵ 2h = -10 ⇒ divide both sides by 2

∴ h = -5

∴ h² = (-5)² = 25

∵ c = h²

∴ c = 25

- The completing square is x² - 10x + 25

∵ The equation is x² - 10x = 16

- We will add 25 and subtract 25 to the equation to make the

 completing square without change the terms of the equation

∴ x² - 10x + 25 - 25 = 16

∴ (x² - 10x + 25) - 25 = 16 ⇒ add 25 to both sides

∴ (x² - 10x + 25) = 41

* Use the rule of the completing square above

- Let (x² - 10x + 25) = (x - 5)²

∴ (x - 5)² = 41
