B and C because an acute triangle is a triangle with all sides less that 90 degrees and a scalene triangle has three unequal sides
I have to make certain assumptions about what you mean here by your
3 ≤ 4 + 3 x / 2 ≤ 2: <span>3 ≤ 4 + 3x/2 ≤ 2. Is that correct or not?
If correct, let's elim. the fractions by mult. all 3 terms of this inequality by 2:
2(</span> 3 ≤ 4 + 3x/2 ≤ 2) => 6 ≤ 8 + 3x ≤ 4
Now subtract 8 from all three terms:
6-8 ≤ 8-8 + 3x/2 ≤ 2-8, or -2 ≤ 3x ≤ 4-8, or -2 ≤ 3x ≤ -4
Isolating x: -2/3 ≤ x ≤ -4/3
There's a basic problem here: -2/3 is not ≤ -4/3.
Please double check to ensure that you have copied down the original problem exactly as it was given.
Answer: 16x + 16x + 13x = 180°
Step-by-step explanation:
16x + 16x + 13x = 180° add all variables
45x = 180° divide both sides by 45
x = 4 Substitute 4 for x for each angle, and then you have your measurements!
Hope this helps! Please give brainliest :)
There are 8 cars which gives between 30 to 50 miles per gallon.
Step-by-step explanation:
- Stem-and-leaf plot are one of the most classical form of plotting.
- The left hand side of vertical line is stem and right is leaf.
- unit digit is leaf and tenths digit is stem.
- 0-9,10-19,20-29,30-39,40-49,50-59,60-69 is range.
- Plotting is done by the number which comes between the range.
- Example between 10-19 there are two points 19 and 19.
- They use discrete variable not continuous.
- The are easy to understand because discrete is counting numbers.
From what I got, you will need 62 <span>centiliters.</span>
