The line n intersects line m and at the point of intersection two angles are formed, which are 3x and x.

Please note that angles on a straight line equals 180 degrees. That means angle 3x and angle x both sum up to 180. This can be expressed as;

3x + x = 180

4x = 180

Divide both sides of the equation by 4 (to eliminate the 4 on the left hand side and isolate the x)

x = 45

How would I figure out what L= is if V=168 yd W= 7 yd H= 3 yd?

Mariulka [41]

We can assume that the shape is a rectangular prism by the given dimensions

Volume of a rectangular prism
Volume = Area of Base × Height of prism
= Length × Width × Height of prism
Substitute!
168 = L × 7 × 3
168 = L × 21
Divide 21 on either sides to isolate L

$\frac{168}{21}$ = $\frac{L*21}{21}$
21 and 21 cancels out

8 = L
L = 8 yd

Is times and divide the same explain

iVinArrow [24]

Times means
2 times 3 means 3+3
4 times of 3=3+3+3+3

divide is
4 divided into 2 parts=2
6 divided into 3 parts=3

but you could multiply by a fraction and essensially divide

they are different
