Answer:
5+2=7x+3x= 10x is the right answer
x= +7 or x=2-7 let me know if you need an explanation <3
Answer: 9-2 & -2-(-9)
Correct me if I'm wrong.
Step-by-step explanation:
Answer:
A) 14
Step-by-step explanation:
BC is congruent to DC in saying this you can plug the equations to each other and solve for y and then put its back into the equation for BC to get the length.
3y+5=5y-1
subtract 3y from both sides --> 5=2y-1
add 1 to both sides --> 6=2y
now get y alone, divide by 2 by both side --> y=3
plug y in back to 5y-1 --> 5x3-1
15-1
BC = 14
