Answer:
solve simultaneously
start by labeling them equation 1 and 2 then choose whether you want to make x or y the subject from knew of the equations
Here’s the answers hope this helps.
17/51=8/x <-- Cross multiply
17x=408 <-- Divide 17 by both sides
x=24
The shortest side is 24 or B.
<span>hypothesis :-
if x=30, then 3/4x+5≠20
let Q:- x=30 P:- 3/4x+5≠20
we need to prove if Q then P (Q →P)
proof :-
lets assume 34x+5=20 is true
now x=30
so
3/4(30)+5=27.5 ≠20
which is a contradiction

Answer:
y=2.5
Step-by-step explanation:
