It is assumed that the equipment will lose value at a constant yearly rate. Then we can find a linear function to represent the value of the equipment.
The rate at which the equipment loses value is $ 875 / 5 years =$ 175 / year.
a) y = 875 - 175x
b) x = 2 => y = $875 - [S175/ year] (2year) = $875 - $350 = $ 525
c) y = 200 = 875 - 175x => x = [875 - 200] / 175 = 3.86 years
Let the number of girls be g.
Let the number of boys be b.
Now we can write these equations;
3g + 4b = 92 ..........(1)
g + b = 26 ...............(2)
b = 26 - g ................(3)
Plugging the expression for b in (3) into (1), we get:
3g + 104 - 4g = 92 ......(4)
Solving (4) we get
g = 12
So the number of girls in the class is 12.
Answer:
98x-2
Step-by-step explanation:
(212x-7)+(-114x+5) = 212x-7-114x+5
= 98x-2
