Maristella is constructing an isosceles triangle to use as a model in her Algebra class. The perimeter of her triangle is 24 cm.

Vlada [557]

Isolating s, the equation written in terms of s is:

$s = 12 - 0.5b$

-------------------------

The equation for the length of the third side, as stated in the problem,("Maristella uses the equation b = 24 – 2s to find b, the length of the triangle's third side") is:

$b = 24 - 2s$

To solve for the lengths of the congruent sides, we isolate s, thus:

$b = 24 - 2s$

$2s = 24 - b$

Inverse of multiplication is division, thus:

$s = \frac{24 - b}{2}$

Separating into two fractions:

$s = \frac{24}{2} - \frac{b}{2}$

Solving each fraction:

$s = 12 - 0.5b$

Due today. Pls help.

X is 19
Explanation: because the opposite side of the angle is 134 degrees the other side also has to be 134 degrees. So we do 134-20 which is 114 and then 114 divided by 6 because the number next to x is 6 and the number that is x has to be 19 as 19x6 is 114.
I think this is the right answer and I hope it helps :)
