Answer:
t=1
Step-by-step explanation:
16-2t = t + 9 +4t
combine like terms
16-2t = 5t + 9
add 2t to both sides
16-2t+2t = 5t+9+2t
combine like terms
16=7t+9
subtract 9 from both sides
16-9=7t+9-9
combine like terms
7=7t
divide both sides by 7
t=1
It'll be 4^2+ 3^2 then the answer you get you take the square root of it which will give you the hypotenuse.
Your answer would be 5 because square root of 25 is 5
If u want the formula it's a^2+b^=c^2
C is the hypotenuse and a and b is the lengths

solve for 1 variable
solve for x in seond eqution
divide everybody by 2
x+2y=8
minus 2y
x=8-2y
sub 8-2y for x in other equation
3(8-2y)-2y=12
24-6y-2y=12
24-8y=12
minus 24
-8y=-12
divide -8 both sides
y=3/2
sub
x=8-2y
x=8-2(3/2)
x=8-3
x=5
(5,3/2)
