Answer:
Solution =
=
5
Step-by-step explanation:
1. Rearrange Terms
100 + 30x = 50x
30x + 100 = 50x
2. Subtract 100 from both sides
3. Simplify
4. Subtract 50x from both sides
5. Simplify

Answer:
see explanation
Step-by-step explanation:
The perimeter is the length of all 6 sides of the polygon.
Note that the 2 unknown sides are
8 - 4 = 4 mm and 8 - 2 = 6 mm
Starting with the left side
Perimeter = 8 + 2 + 4 + 6 + 4 + 8 = 32 mm
The polygon can be split into 2 rectangles.
The lower rectangle with sides of 8 and 4
and the upper rectangle with sides 2 and 4
Area = (8 × 4) + (2 × 4) = 32 + 8 = 40 mm²
Answer:
41.6666% is a required percent of 48 is 20
20/48×100%=41.6666%
Angle 3 = 60°
Angle 4 = 60°
Step-by-step explanation:
To find angle 3 we have to use the straight angle that is formed with angle C. Angle C is the same value as angle 2 (120°) so all we have to do now is make an equation by subtracting angle C (120°) from 180°. 180°-120°=60°. So 60° is the value of angle 3.
Angle 4 is also 60° because it is the same angle as angle 3. So the value of angle 4 is 60°.
Another way to solve this problem (shown in the picture) is using the value of angle 1 (60°) and when you have the value 60° and there are triangles formed within the angle (highlighted in the picture) you know that all the angles within the triangle are going to be 60° because all angles within a triangle add up to 180°. So if we were to use this rule the equation would look like 60°+60°+60°=180°. Angle 3 in the green triangle would be equal to 60° because of the fact that one angle was already confirmed as being 60° so because of that all the angles in the triangle have to add up to 180° so the all the angles must be 60°. Angle 4 in the red triangle would also be equal to 60° for the same reason mentioned above.
So therefore the answer to this question is Angle 3 = 60° and Angle 4 = 60°

1. 2 (9) + 27 = 45
9 × 2 = 18
18 + 27 = 45
2. <span>12,599,000</span>
3. 108 ÷ 12 = 9
4. 18 ÷ 2 = 9
Hope I helped ya!!!☺☺☺☺☺
