Answer:

x = 5

Step-by-step explanation:

Equating the terms :

x + 3 = 2x - 2

Add 2 on both sides :

x + 3 + 2 = 2x - 2 + 2
x + 5 = 2x

Subtract x from both sides :

x + 5 - x = 2x - x
x = 5

9. All the students in the sixth grade either walk home or take the bus home after scho

timurjin [86]

There are 250 students in sixth grade

Solution:

Given that, All the students in the sixth grade either walk home or take the bus home after school

From given,

Number of students walk home = 170

Let "x" be the total number of students in school

32% of the students take the bus

Thus, 32 % of "x" takes bus

To find: total number of students in school

Total students = Number of students walk home + number of students takes bus

$x = 170 + 32 \% \times x\\\\x = 170 + \frac{32}{100} \times x\\\\x = 170 + 0.32x\\\\x - 0.32x = 170\\\\0.68x = 170\\\\x = 250$

Thus there are 250 students in sixth grade

This is because you can multiply the terms after the log and set them equal to 10^1. or simply 10. This would give you 7(x-4)= 10. Solve for x.
