Answer:
c
Step-by-step explanation:
Hello there!
The correct answer is B. Why? Well, we cannot choose A, because we don't have a multiplication sign. We cannot choose C because we also don't have a multiplication sign. However, since we have a PLUS sign and a Subtraction sign, we can say that the correct answer is option B.
3x + 1 < -2x + 8
We wanna start by subtracting 1 on both sides
3x + 1 - 1 < -2x + 8 - 1
3x < -2x + 7
Add 2x on both sides
3x + 2x < -2x + 7 + 2x
5x < 7
x < 7/5
I hope this answer helps! As always, it is my pleasure to help students like you. If you have any additional questions, feel free to comment them down below. I'll see you around!
Answer:
105
Step-by-step explanation:
By solving for the other triangles, we know that the angles of a triangle add up to be 180 degrees. The angle for the triangle on the left is 25 and for the triangle on the right is 50. So we have the measurements, 25, 50 and x for our middle triangle from which we can see x=105
