The slope of the line is 2/3, so the angle is arctan(2/3) ≈ 33.69°.
Answer:7 + 11x
Step-by-step explanation: you add your letter and number that were in the brackets the since 7 has no number the equation would end and become 7+11x
S1: 7x - 4x - 2 = 6 OK
S2: 3x - 2 = 6 OK
S3: 3x - 2 + 2 = 6 WRONG, correct is 3x - 2 + 2 = 6 + 2
Answer: c. Step 3, because a number has been added only to one side of the equation.
Answer:
Step-by-step explanation:
<u>STU is an equilateral triangle. And:</u>
- ST = 2x - 1
- SU = 5x - 37
- TU = x + 11
<u>All sides are equal. Then take one pair and solve for x:</u>
- 2x - 1 = 5x - 37
- 3x = 36
- x = 12
<u>Substitute x to find the side length:</u>
- 2x - 1 = 5x - 37 = x + 11 = 23
