Y = mx + b
m = 3 (given), then

y = 3x + b. Now calculate b by plugging in the coordinates (1,5)

5 = 3(1) + b and b = 2

The equation is then y = 3x+2

Find the perimeter of the following trapezoid: 6 ft 2.5 ft/ 12 ft 2.5 ft 8 ft

sasho [114]

Answer:

31ft

Step-by-step explanation:

6 ft + 2.5 ft + 12 ft + 2.5 ft + 8 ft = 31ft

I assumed the slash in the space between 2.5ft and 12ft was an error, so I ignored it in the solution to this problem.

Besides that, perimeter is found by adding all sides of the shape or figure together, and the sum of that is the perimeter.

The basic formula for perimeter is:

base + height + base + height.

I do not think you square perimeter as you do area (e.g. 31ft^2).

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:

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!
