A student is 7 years old. If you triple the teachers age and add the student's age the answer is 163. How old is the teacher?
pogonyaev

Answer:

52

Step-by-step explanation:

We can write this out as an equation. Let's say that the teacher's age is x. Triple the teachers age plus the students age is 163, which can be written out as:

3x + 7 = 163

We want to isolate the variable, so subtract 7 from both sides. This gives us:

3x = 156

Finally, we divide both sides by  3, giving:

x=52

So the teacher is 52 years old.

Hope this helps!

A square patio has a perimeter of (32x+8) feet. What is the length of the patio?
Sonbull [250]

The perimeter of the square patio is the sum of its side lengths

The length of the patio is: 8x + 2

The given parameters are:

\mathbf{Shape = Square}

\mathbf{Perimeter = 32x + 8}

The perimeter of a square is:

\mathbf{Perimeter = 4 \times Length}

So, we have:

\mathbf{4 \times Length = 32x + 8}

Divide both sides by 4

\mathbf{Length = 8x + 2}

Hence, the length of the patio is: 8x + 2
