2)  1/12 times 3/5 = 1*3 = 3     12*5 = 60     3/60 3 and sixty divided by 3
       = 1/20 ANSWER

3) (-5/8)(-12/5) = the two 5's cancel each other. This becomes (-1/5)(-12/5) = 12/8 12 and 8 divided by 4 
= 3/2 ANSWER

4) 6/7 divided by 8/7 becomes 6/7 times 7/8 
7's cancel each other  becomes 6/8

Point x is at 2/3 on number line. On the same number line point y is the same distance from 0 as point x but has a numberator of
Yanka [14]

Answer:  The answer is 12.

Step-by-step explanation: Given that a point 'x' is lying at \dfrac{2}{3} on the number line. Another point 'y' is also lying at the same distance from 0 but has a numerator of 8. We are to find the denominator of 'y'.

Since 'x' is lying at \dfrac{2}{3} on the number line so its distance from 0 will be

d_x=\dfrac{2}{3}-0=\dfrac{2}{3}.

Let the denominator of 'y' be p, then its distance from 0 will be

d_y=\dfrac{8}{p}-0=\dfrac{8}{p}.

According to the given information, we must have

d_x=d_y\\\\\\\Rightarrow \dfrac{2}{3}=\dfrac{8}{p}\\\\\\\Rightarrow p=\dfrac{8\times 3}{2}=12.

Thus, the denominator will be 12.

If all the rows and columns have the some number of blocks, then

(number of blocks in each row) times (number of blocks in each column)

must be a perfect square.

'121' is the only choice on the list that's a perfect square.  It's the square of 11.

Write the equation in vertex form of the parabola with the vertex (-4,-4) that goes through the point (-2,-16)
Brrunno [24]

Answer:

- 3(x + 4) {}^{2}  - 4

Step-by-step explanation:

Vertex form is

a(x - h) {}^{2}  + k = f(x)

We know that h and k are both -4. Let x be -2 and y be -16.

a( - 2  + 4) {}^{2}   - 4 =  - 16

a(2) {}^{2}  - 4 =  - 16

4a - 4 =  - 16

4a =  - 12

a =  - 3

So the equation in vertex form is

- 3(x  + 4) {}^{2}  - 4
