How many solutions can be found for the equation 5x + 3(x − 1) = 10x − 2x − 3? None
One
3. Two
4. Infinitely many

2 UWU IM S SMART LOL

4. Infinitely many

Step-by-step explanation:

5x + 3(x − 1) = 10x − 2x − 3

5x+3x-3=8x-3

5x+3x-8x=3-3

0=0

x∈R

step-by-step explanation:

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
