1. Move 2/x to the left side of proportion by changing sign before it:
3/x - 1 - 2/x = 4
2. Move 1 to the right side of proportion and change it's sign as well:
3/x - 2/x = 4 + 1
3. Sum numerators in the left side of proportion since they have common denominator (x) abd also sum the numbers in the right side too:
(3-2)/x = 5
4. Calculate numerator in the left side of proportion:
1/x = 5
5. Move 1 to the right side of proportion by dividing that side by it:
x = 1/5

Step-by-step explanation:
multiply the weeks by the number of cars first, and then times it by the amount of money per car
(weeks×cars per week) money per car
Answer:
9
Step-by-step explanation:
All triangles (3 sided polygons) have angles added up to 180, so we can do the following:
(7x-1) + (7x+8) + (5x+2) = 180° <em>- equation</em>
7x-1 + 7x+8 + 5x+2 = 180° <em>- "distribute"</em>
19x - 1 + 8 + 2 = 180°<em> - combine the x terms</em>
19x + 9 = 180° <em>- combine the integer terms</em>
19x = 171 <em>- subtract 9 form both sides</em>
x = 9 <em>- divide both sides by 19</em>
Answer: 504 cm^2
The surface area of the shape is:
3 3 * 3=9
9 * 7=63
63+9=72 * 7
=504cm^2
Yo dawg it’s B 100% just took this one
