L = 4w
2L + 2W ≤ 130 cm
I would use the substitution method for this one.
Answer = 2(4w) + 2w ≤ 130 cm
We know already that desk A and desk B are on the same column, since both coordinates' x factors are 7. So all we need to do now is find the differeance of 2 and -8. So, we get the [very simple] equation 2 - (-8) = d. Now, when you subtract a negative, it's pretty much just adding, so we can simplify this equation to 2 + 8 = d, and we all know 2 + 8 = 10. So the distance between the two desks is 10 units.
Hope this helps! If there is anything wrong feel free to point it out.
Have a nice day!
Answer:
x=20
it told me the answer is too short but that answer is right
The formula that we want to use here is S = D/T.
S = Speed
D = Distance
T = Time
So, we know that S = 550 and T = 3.5, so we can plug them in.
We get 550 = D/3.5
Multiply by 3.5 on each side, and you figure out that the plane has traveled 1925 miles.
The <em>correct answer</em> is:
24°.
Explanation:
To find the degrees of rotational symmetry, you divide 360° by the order of symmetry.
For a regular 15-gon, the order of symmetry is 15 (there are 15 vertices that the polygon can be turned to and be mapped onto itself).
This means the degrees of symmetry would be
360/15 = 24°.
