This question is worded slightly strangely but I believe I understand it.
To eliminate x, multiply the second equation by 8, so that it becomes 4x + .8y= 96
Then you can subtract 4x on the top by 4x on the bottom to eliminate it.

Answer:
The order of the sides of each triangle from shortest to longest.
Step-by-step explanation:
Given the triangle CDE
We know that the longest side in a triangle is opposite the largest angle, and the shortest side is opposite the smallest angle.
as
angle D=35° < angle C=60° < angle E=85°
It means:
- The opposite side of the angle D is the shortest side which is CE.
- The second-longest side is the opposite of the angle C = 60° which is DE.
- The opposite side of the angle E i.e. CD is the largest side.
Therefore,
angle D=35° < angle C=60° < angle E=85°
CE < DE < CD
Hence, the order of the sides of each triangle from shortest to longest.
Answer:
x = 10
Step-by-step explanation:
Mathematically, the sum of the interior angles of a triangle is 180
Thus, we have it that;
55 + 45 + (5x + 30) = 180
100 + 5x + 30 = 180
5x = 180-30-100
5x = 50
x = 50/5
x = 10
IO/2.4 = I5/x
IOx = 36
x = 3.6
