X + x + x + x - 20 is equivalent to 4x - 20 because you can add the like terms, or the x's.
If you would like to know how many boys play video games daily, you can calculate this using the following steps:

Answer:
1,42 * 10 ^ -5
Step-by-step explanation:
La notación científica también se conoce como forma estándar.
Tenemos que realizar la siguiente operación y dejar el resultado en forma estándar.
Entonces;
0,00000826 * 235 × 10 ^ -7 / 0,0017 × 10 ^ -2
También;
8.26 * 10 ^ -6 * 2.35 * 10 ^ -5 / 1.7 * 10 ^ -5
= 19,411 * 10 ^ -11 / 1,7 * 10 ^ -5
= 1,42 * 10 ^ -5
4% of 200 7 graders= 8, so 8 are expected to move by the end of the year. but if 12 students actually moved instead, there was 4 more moves than we expected. I hope this helped..!
