Step-by-step explanation:
<u>Step 1: Define</u>
3x + 6(x - 11) = 5x - 18
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 6: 3x + 6x - 66 = 5x - 18
- Combine like terms: 9x - 66 = 5x - 18
- Isolate <em>x</em> terms: 4x - 66 = -18
- Isolate <em>x</em> term: 4x = 48
- Isolate <em>x</em>: x = 12
6 lb9 oz is the answer to this question.
It’s the third choice because the highest degree is three and there are three terms. FOR QUESTION 3
The first two choices for QUESTION 4
Area of triangle = 1/2 base x height
15.588 = 1/2 * base x 5.196
15.588 = base x 2.598
base = 15.588 / 2.598 = 6
equi center of triangle = 1/3*5.196 = 1.732
radius of circle = Sqrt(1.732^2 + 3^2) =
sqrt (2.999824 +9) =
sqrt(11.999824) = 3.464
rounded to nearest tenth = 3.5 inches
