Answer:
35.8°
144.2°
Step-by-step explanation:
Definition of Supplementary Angles: They add up to 180°
Step 1: Set up equation
3x + 12x + 1 = 180
Step 2: Solve
15x + 1 = 180
15x = 179
x = 11.93
Step 3: Find angles
∠1 = 3x
m∠1 = 3(11.93) = 35.8°
∠2 = 12x + 1
m∠2 = 12(11.93) + 1 = 144.2°
Hi!
To solve this inequality, we have to isolate x on one side. Whatever we do to the equation we have to do it on both sides.
1.30x + 5.20 ≤ 18.20
Subtract 5.20 from both sides.
1.30x + 5.20 - 5.20 ≤ 18.20 - 5.20
1.30x ≤ 13
Divide by 1.30 on both sides.
1.30x/1.30 ≤ 13/1.30
x ≤ 10

Hope this helps! :)
Good morning. I’m sorry to say I can’t really see what the numbers are in your photo. I zoomed in and circled what I could on my picture.
For your first question (6), subtract the difference between the two points that I have circled. Each of those marks the upper quartile for each team.
For (7), I need to know which line or dot is 210. If it’s the line in the middle of the box, the answer is 50%. If it’s the line at the right side of the box, the answer is 75%
For (8), again, I need your help to know where 220 is.
If you can put some answers in the comments, I’m happy to keep helping you.
Answer:
4
Step-by-step explanation:
Because it will be positive
Answer: C
Step-by-step explanation:
I’m pretty sure it’s c because x isn’t less than -2. It goes forever in the directions of positive and negative infinity
