Step-by-step explanation:
Solve the equation:
-First you add both sides 9.6:
-Then, you divide both sides by 3.2:
Answer:
The distance that Peter rides is:
Step-by-step explanation:
To identify the miles that Peter rides, you must imagine the triangle with measures: 3.36 miles, 4.18 miles, and 5.61 miles. How you can suppose, Peter regularly rides exactly by each side of the triangle mentioned, then you must find the perimeter of the triangle to identify the miles that Peter rides, remember that the perimeter of an irregular triangle is:
- Perimeter of a triangle = side + side + side
If you replace the formula, you obtain:
- Perimeter of a triangle = 3.36 miles + 4.18 miles + 5.61 miles
- <u>Perimeter of a triangle = 13.15 miles</u>
3x - y = 9
y = -2x + 11
3x - (-2x + 11) = 9
3x + 2x - 11 = 9
3x + 2x = 9 + 11
5x = 20
x = 20/5
x = 4
y = -2x + 11
y = -2(4) + 11
y = -8 + 11
y = 3
solution (where the lines intersect) is (4,3)
4.5 x 6.2 = 27.9
Hope that helps
