I'll mark brainliest!me, i'm desperate for an explanation lol!

1: how do you find 3 4/5x - 2 1/2 for x = -10 step by step?

2: simplify the expression step by step, listing the property of operations used.
-5/6 x (-5/8) x 6/5 =

you so much!

Question 1: x = -75/38

Question 2: -5/6 X (-5/8) X 6/5 = 5/8

Step-by-step explanation:

Question 1:  3 4/5x - 2 1/2 for x = -10

Given equation is in whole number form so by simplifying we get:

19/5x - 5/2 = -10            (As 5*3 + 4 = 19  and 2*2+1 = 5)

Now Add 5/2 on both sides we get:

19/5x - 5/2 +5/2 = -10 + 5/2

19/5x  = -10 + 5/2

Taking LCM we get:

19/5x = (-20+5)/2

19/5x = -15/2

Multiply both sides by 5/19

x = -15/2 * 5/19

x = -75/38

Question 2:

= -5/6 X (-5/8) X 6/5

Multiplying first 2 fractions we get:

= 25/48 X 6/5   ("-" multiplied by "-" gives "+")

= 5/8 X 1/1

Multiplicative identity

= 5/8

I hope it will help you!

they can both be solutions depends on the equation
