−4(3.2−3k)+0.2(9+15k)
Distribute:
=(−4)(3.2)+(−4)(−3k)+(0.2)(9)+(0.2)(15k)
=−12.8+12k+1.8+3k
Combine Like Terms:
=−12.8+12k+1.8+3k
=(12k+3k)+(−12.8+1.8)
=15k+−11
Answer:
Step-by-step explanation:
Let the number be x
- 5x - 9 = 4x + 1
- 5x - 4x = 1 + 9
- x = 10
Proof:
Answer:
6
Step-by-step explanation:
XY = 3x – 1, YZ = 5, and XZ = 5x – 8,
We know that XY + YZ = XZ, so
3x - 1 + 5 = 5x - 8
3x + 4 = 5x - 8
3x + 12 = 5x
12 = 2x
6 = x
I think is C tbh sorry if that’s wrong my fault
Okay so you're correct answer in this situation would be A but it could alsobe C
