220-220r=160
Solve for r to get the discount rate
r=0.2727
r=0.2727×100
r=27.27%
Check
220−220×0.2727

Multiple choice questions = 5
True questions = 15
Given that:
Total number of questions = 20
Total worth of point = 100
Multiple choice questions (M) = 11 points each
True false questions (T) = 3 points each
Hence,
M + T= 20 ____(1)
11M + 3T = 100 ____(2)
M = 20 – T
Using the relation in (2)
11(20 – T) + 3T= 100
220 – 11T + 3T= 100
220 – 8T = 100
-8Tf = 100 – 220
-8T = – 120
T = 120/8
T = 15
Mc = 20 – 15

Answer:
C) 
Step-by-step explanation:
The equation of a straight line is given by:
y = mx + b
where m is the slope of the line, b is the y intercept (value of x when y is 0) and y, x are variables.
The equation of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by:
From the graph, the line passes through (0, 0) and (10, -2), hence the equation of the line is:
Answer:
Step-by-step explanation:
The first equation is the weights of the rabbit and the ferret together which is
r + f = 7.
The second equation puts the weight of the ferret in terms of the rabbit. If the ferret's weight is 2 pounds more than the rabbit, then
f = r + 2 (the word "is" means equals). Since we know what f is equal to, we will sub it into the first equation and solve for r:
r + (r + 2) = 7 and
2r + 2 = 7 and
2r = 5 so
r = 2.5 pounds.
A rabbit weights 2.5 pounds and the ferret weights 7 - 2.5 which is 4.5 pounds.
Answer:
19 days
Step-by-step explanation:
Because they do a school show every Monday and a library show every fifth day of the weekday and weekend so all you have to do is count the days from the Monday they’re doing a show at both places but keep in mind that they do library shows on the fifth day of the weekend and weekday that’s how you get to 19
