Answer: I did the test too
The range is the highest number in the set minus the lowest number in the set so
84-16=
68
Answer:
10 days
Step-by-step explanation:
Jenny has read 50 pages and will read 15 each day.
The equation would be: 15x+50
Mark will read 20 pages daily.
The equation would be: 20x
In both equations x represents days.
You set both equal to each other because you want to know when they read the same amount of pages.
15x+50=20x
...you subtract 15x from both sides
50=5x
...and divide by five to get: 10 days
The only way i can think of working out this question is this:
t = time p = phone calls
insert what we know:-
93 = p + 50
make P on its own:-
take away 50 from each side
43 = p
switch (you don’t HAVE to do this) :-
p = 43
So, shivani has to route a total of 43 phone calls to spend a total of 93 minutes on the phone.
This mean you need to be more careful in driving a car
