<span>1.) f(x)=x+1/5 is already in that form
</span>2.) f(x)=3/2x-1/2
X = 180 - 150 = 30°
z = 180 - 100 = 80°
y = 180 - 30 - 80 = 70°
Answer: x = 30, y = 70, z = 80

It says the scale factor is 1:25000, so for every one part there is actually 25000. So for every centimeter, there is actually 25000 cm. See that we multiplied by 25000.
So for 6.8cm, multiply by 25000 to get 170000cm.
The real distance represented is 170000cm.
19) Just work out one step at a time using order of operations.
Do parentheses first. 7^2 = 49, and 3^3 is 3*3*3 which is 27.
Now you have [8(49 - 27) ]/ sqrt121.
Finish simplifying the parentheses. 49 - 27 is 22.
[8(22)] / sqrt121.
Now multiply 8 times 22, which is 176.
176 / sqrt 121
The square root of 121 is 11.
176/11.
= 16
It would be 12
10% = 6
6 x 2 = 12
