<span>The book has sold 442,696 copies to date.
This was calculated by making a proportion: 8.9 : 39,400 = 100 : X where X Is the number of copies sold.
Then I calculated 39,400*100/8.9 to obtain the answer</span>
Answer:
5.
2.4 = E
-1 4/5 = B
-0.2 =C
-2 3/5 = A
0.6 = D
6. one line under -1
Step-by-step explanation:
5. On the number line each short line is by 2 so basically 2 + 2 + 2
6. -4/3 = 1/1/3 (simplify)
Part a:
x + y = 55
y = x + 25
part b:
jackie runs 15 minutes every day.
part c:
it is not possible for jackie to spend 45 minutes a day dancing, since the time she spends dancing and running is 55 minutes, and we know that it takes 15 minutes to run
step-by-step explanation:
let's call and while jackie is dancing
let's call x while jackie is running
then we know that jackie runs and dances for a total of 55 minutes every day
this means that:
x + y = 55
we also know that jackie dances 25 minutes more than she runs.
this meant that:
y = x + 25
now we substitute the second equation in the first and solve for the variable x
x + x + 25 = 552x = 55-252x = 30x = 15
jackie runs 15 minutes every day.
now we find the value of the variable -y
15 + y = 55y = 55-15y = 40
note that it is not possible for jackie to spend 45 minutes a day dancing, since the time she spends dancing and running is 55 minutes, and we know that it takes 15 minutes to run
