Answer:

3x + 5x - 4 = 1

Step-by-step explanation:

Given the equation

3x + y = 1

We must substitute the following equation:

y + 4 = 5x

So first we'll isolate y from the second equation so that then we can substitute its solution in the first equation:

y + 4 - 4 = 5x - 4

y = 5x - 4

Now we can substitute y in the first equation:

3x + y = 1

3x + 5x - 4 = 1

Solve the second equation for y so that you can substitute it in for y in the first equation..

y = 5x - 4

Substitute:

3x + (5x - 4) = 1

There are 550 students at Martin Middle School. One bundred and eighty- seven students walk to school. what percent of the stude
Anvisha [2.4K]
For a question like this, all you have to do is remember that a percentage is simply a fraction expressed as a decimal. So, all we have to do is:
\frac{187}{550}, and then multiply our decimal answer by 100 to get the percentage:
\frac{187}{550} = 0.34
0.34 x 100 = 34
Therefore 34% of the students walk to school.
I hope this helped and remember to please try and understand the maths that got the answer, not just writing the answer down :))
