Answer:
Step-by-step explanation:
if f(x)=3x-1 and g(x)=2x+5 then
f(x)-g(x)=3x-1-(2x+5)
f(x)-g(x)=3x-1-2x-5
f(x)-g(x)=x-6

Answer:
20
Step-by-step explanation:
1/3 = .3
6/.3 = 20
Multiply the average by the number of exams to find total points:
8 x 55 = 440
9 x 60 = 540
The score of the 9th exam is the difference between the two totals:
540 - 440 = 100
They scored a 100
Answer:
Since we have two semi-circles we can say that we have a full circle. using the circle area formula we can say that
3.14*2^2 = 12.56 cm
Using the rectangle area formula we can say that
19*4 = 76 cm
Adding them both together is
12.56 + 76 = 88.56 cm
So the bookmark has an area of 88.56cm^2
