Answer:
Think
Step-by-step explanation:
4x - 6 + 2x = 18
You are solving for x so obviously you have to have your x variable on one side of the equal sign by itself.
So how do you do that? Combine the same calues together and seperate the rest
4x + 2x = 6x
6x = 18 + 6
6x = 24
x = 3
Practice practice practice. Simple stuff. You got this!
Answer:
- angular speed: 61.3 radians/s
- tangential speed at .193 m: 11.8 m/s
Step-by-step explanation:
The forward speed of the center of the tire with respect to the ground is the same as the tangential speed of the tire at its full radius of 0.315 m, relative to the axle.
The angular speed of the tire is the ratio of tangential speed to radius:
(19.3 m/s)/(0.315 m) ≈ 61.27 radians/s
The tangential speed at any other radius is the product of angular speed and radius. At a radius of 0.193 m, the tangential speed is ...
(0.193 m)×(19.3 m/s)/(0.315 m) ≈ 11.825 m/s ≈ 11.8 m/s
Answer:
see below
Step-by-step explanation:
A left-arrow on a number line represents subtraction of a positive number or addition of a negative number. The two left arrows, one of length 0.2, the other of length 0.1, indicate the numbers -0.2 and -0.1 are being added. The end result is the dot at the end of the combined arrows, at -0.3.
The only expression that is true and corresponds to this description is the one shown below.
26*19=494.
480-494=-14

Answer:
577.50
Step-by-step explanation:
You need to add all the areas of the separate pieces together, so the triangles are:
Triangle: 7 (12) (1/2), but you have 2 of them so don't divide by 2, just 7(12) so that part is 84
Top flap is 15(7) = 105
Middle is 15(12) = 180
Bottom is 15(13.89) = 208.35
Add them all together 84+105+180+208.35 = 577.50
