For the second one, it is C

0.52 = 52/100

It's 52/100 because 0.52 = 52%. 52% then equals 52/100.

52/100 = 13/25

So the answer is 13/25

base=4m

height=7m

hypotenuse can be determined using pythagoras law

How dou you solve for 6x+4y=24?

lilavasa [31]

You could first solve for y, assuming x is 0, and y = 6. Then solve for x, and that means y = 4.
