answer all of above asap 20 points

a) 2 b)1  c)1/3 d)5/4

Step-by-step explanation:

Hi to solve this equation we simply have to replace the variable with the number given, and then isolate the variable.

5 x 2/5 = 10 /5 = 2

5/5= 1

In this case after replacing the number we have to simplify it.

2 (2/3) -1 =

4 /3 -1 =

4/3 -3/3 = 1/3

In this case, to add fractions first we have to multiply the top and bottom numbers of the second fraction by 3, to have the same denominators.  

1/2 + 3/4 =

2/4 +3/4 = 5/4

Feel free to ask for more if it´s necessary or if you did not understand something.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
