Answer:
the number = 8/5 or 1 3/5 or 1.6
Step-by-step explanation:
n = the number
5/2n - 11 = 4
5/2n - 11 + 11 = 5 / 2n
5/2n = 4
5/2n / 5/2 = n
4 / 5/2 = 8/5

Answer:
6.43
pls follow me and mark brainliest ...thank u
Step-by-step explanation:
length of side x will be
Tan tita = opp/adjacent
tan65 = x/3
tan 65 is 2.14
so...you are left with 2.14=x/3
by cross multiplying
x= 2.14 × 3
= 6.43
x > -3
x < 3
<em><u>-3 < x < 3</u></em>
question didn't mention about "x is real number, or positive, or negative etc".. so we can't say anything more
for example: x can be -2,-1,0,1,2
but if only positive, x can be = 1,2
" " negative, x can be = -1, -2
Hope this helps ^-^
