5x-3=42. To solve you add three to both sides making the equation 5x=45. Then you divide both sides by five, and you get 9 as your answer.
D for sure I hope it helps and I know I’m 100% right because I already had this question somewhere else dude so yeah
Combine (subtract) 3n and 2n to get 1n or n. Then you have n -5n =10n add 5n to 10n to get 15n. divide the 15 from n and your answer is n=15
Answer: m∠D = 65°
Step-by-step explanation:
The best solve method for problems like this is say the sum of the angle values equals 360.
2x-15+2x-15+x+x = 360
Then from here you just simplify.
4x+2x-30 = 360
6x = 390
x = 65
So the measure of Angle D equals 65 degrees.
