Step-by-step explanation: TS 5 15 8 36
L = W + 10 cm
Perimeter = 2(L + W)
Perimeter = 70 = 2(W +10 +W)
70/2 = 2(W +10 +W) / 2
35 = (W +10 +W)
35 = 2W +10
35 - 10 = 2W +10 - 10
25 = 2W
25/2 = 2W/2
25/2 cm = W W = ?? cm
L = W + 10 cm
L = 25/2 + 10 cm L = ?? cm
X is unknown. There’s no answer to the problem stating what X could possibly be.
Answer:
since the lengths are consecutive odd numbers and the perimeter of the triangle is 51cms. Let x be the unknown length.
so 3x=51 ; x=17 . now the sides can be 15cms, 17cms, 19cms.
check Add them up it is 51cms which is the perimeter and the consecutive odd numbers
Well, in order to first determine the slope or y-intercept, you must put change the equation to this format: y=mx+b.
m=slope and b=y-interceptI
in order to do that, you must change this equation.
x+3y=9
-x -x
----------
3y=9-x
Then, rewrite it as:
3y=-x+9
_______
3 3
simplify to
y=-x/3 +9
