Answer:

x = 1

Step-by-step explanation:

There are a couple of ways to solve this. One is to graph the left side of the equation, graph the right side of the equation, and look for the point where those graphs intersect. It is at x = 1. The first attached graph shows this solution.

Another method for solving such an equation is to subtract one side from the other and look for the value of x that makes the resulting expression zero.

(-2x +3) -(-3(-x) -2) = 0

A graphing calculator doesn't need to have this simplified. If it is simplified, it becomes ...

-5x +5 = 0

So, the graphed line is y = -5x+5. Its x-intercept is x=1, the solution of the original equation. The graph of this is shown in the second attachment.

The historical walking tour of a town covers a total distance of 5 miles. The map shows that the path of the tour travels 3 inch

kari74 [83]

Since the problem is given all the total walking distance, the first thing we are going to do is find the total distance in the map:
$Diastance_{map}=3+4+2+1$
$Distance_{map}=10$
Now that we have the distance in the map, we can establish a ratio between the walking distance and the distance in the map:
$\frac{5miles}{10inches} = 0.5 \frac{mile}{inch}$

We can conclude that each inch the map represents 0.5 miles of walking distance.

For three consecutive numbers, the sum of the first number, twice the second and 7 less than the third is 133. What are the thre

babunello [35]

Answer:

34, 35, 36

Step-by-step explanation:

1st number = x

2nd number = x+1

3rd number = x+2

So the equation would be:

x+2(x+1)+(x+2)-7=133

x+2x+2+x+2-7=133

4x-3=133

4x=136

x=34
