Answer:
-2 = x
Step-by-step explanation:
4(1-x)+3x = -2(x+1) Distribute
4 - 4x + 3x = -2x -2 Combine Like Terms (On the same sides of the equal sign)
4 -x = -2x -2 Combine Like Terms (On different sides of the equal sign)
4 = -3x - 2 Solve
6 = -3x
-2 = x
Answer:
1
Step-by-step explanation:
since the other side can not be given as a line of symentry
Answer:
First find the circumference of both wheels
C = pi d
Large wheel = 3.14 * 60
= 188.4
Small wheel = 3.14 * 18
= 56.52
Divide them both with divide 600 by the circumference
Large wheel = 600/188.4 = 3.18 or <em>3 rotations</em>
Small wheel = 600/56.52 = 10.61 or <em>11 rotations</em>
<em>b. 2 large wheels. This is because you can cover more distance with large wheels that small wheels. Large wheels are also worth the energy.</em>
