Type a digit that makes this statement true.<br><br> 5,072,<br> 00 is divisible by 8.

lina2011 [118]

The divisibility rule for 8 is that the last three digits have to be divisible by 8.

The third digit of 5072_00(from the right) could be 2, 4, 6, 8, or 0, because 200, 400, 600, 800, and 0 are divisible by 8.

Answer:

The value of x is $\frac{-2}{5}$ .

Step-by-step explanation:

Given expression is:

$\frac{2}{3}(x-2)=4x$

We have to solve this for x.

First we will multiply both sides of the equation by 3

$3*\frac{2}{3}(x-2)=4x*3$

2(x-2) = 12x

2x-4=12x

Now we will be subtracting 2x from both sides of the equation

2x-2x-4=12x-2x

-4=10x

10x=-4

Dividing both sides by 10

$\frac{10x}{10}=\frac{-4}{10}\\\\x=\frac{-2}{5}$

Hence,

The value of x is $\frac{-2}{5}$ .

3. One method you can use to determine whether a triangle is a right triangle, given three side lengths, is to apply the Convers

babymother [125]

Sin < C = 63/65 so m < C = 75.75 degrees

and tan B = 16/63 so m <B = 14.25 degrees

m < C + m<B = 75.75 + 14.25 = 90 degrees

Therefore m < A = 180-90 = 90

therefore the triangle is right-angled.
