Hello!
When you have a non-exact root (irrational number)

$\sqrt{ \frac{3}{16} } \to \frac{ \sqrt{3} }{ \sqrt{16} } \to \boxed{\boxed{\frac{ \sqrt{3} }{4} }}\Longleftarrow(irrational\:number)\end{array}}\qquad\quad\checkmark$

Confusing I tried <br><br> 4x-7+31=4x+2<br><br> But it won’t work <br><br><br> Can someone explain??

Len [333]

Answer:

0=-22

4x−7+31=4x+2

Step 1: Simplify both sides of the equation.

4x−7+31=4x+2

4x+−7+31=4x+2

(4x)+(−7+31)=4x+2(Combine Like Terms)

4x+24=4x+2

4x+24=4x+2

Step 2: Subtract 4x from both sides.

4x+24−4x=4x+2−4x

24=2

Step 3: Subtract 24 from both sides.

24−24=2−24

0=−22.

Answer:

C.

Step-by-step explanation:

Because the vertical line is the line that is parallel to the y-axis,

(V) : x = 1...because it only passes through 1 and has a gradient of (0)

The horizontal line is the line that is parallel to the x-axis

(H) : y = 6...because it passes through 6 and has a gradient of 0

Julian is 10 years younger than Thomas. The sum of their age is 40. What is Thomas age

Karolina [17]

So first we subtract 10 from 40 and get 30. We divide this by the number of people (2) to get Julian's age: 15. We add 10 to this to get Thomas age = 25. 25 + 15 = 40

Thomas is 25 years old.
