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!

If 3(d+1)=4(d–2)<br> then what is the value of 5(d–2)
Sonja [21]

Answer:

5(d - 2) = 45

Step-by-step explanation:

Solve the given equation for d

3(d + 1) = 4(d - 2) ← distribute parenthesis on both sides

3d + 3 = 4d - 8 ( subtract 3d from both sides )

3 = d - 8 ( add 8 to both sides )

11 = d

Then

5(d - 2) = 5(11 - 2) = 5(9) = 45
