8.6x + 3 + 8.6+3 =. 17.2x + 6
5.2+5.2= 10.4
17.2x + 6 = 10.4
Answer:
the equation have infinite solutions
Step-by-step explanation:
if you have that x is equal to x (x=x) the only thing you really know nothing about it.
brainliest please ;)
X + y = 56 ------------------(1)
x:y = 5:3
x/y = 5/3
3 x = 5 y
so, x = (5/3)y---------------(2)
sub (2) in (1)
x + y = 56
(5/3)y + y = 56
5 y + 3 y = 168
8 y = 168
y = 168 / 8 = 21
x = (5/3) x 21
= 35
the value of x - y = 35 - 21
= 14
Answer:
See below.
Step-by-step explanation:
The expression 
is equivalent to the decimal -0.8 or -80%. It is also equivalent to the fractions 
since these simplify to 4/-5.
