Answer:
subtract 2, and add 5 repeatedly
Step-by-step explanation:
49, 47, 52, 50, 55
subtract 2, and add 5 repeatedly
49-2=47
47+5=52
52-2=50
50+5=55
55-2=53
53+5=58
and so on........

Answer:
$13.67
Step-by-step explanation:
Let's say that CD= c and DVDs= d. Four CDs and 4 DVDs cost $164, so the equation will be:
i. 4c + 4d= 164
The cost of the 4 CDs is half the cost of the 4 DVDs, to put into an equation it will be:
ii. 4c= 0.5(4d)
4c= 2d
d= 2c
Then we can substitute the second equation (ii) into the first equation (i). The calculation will be:
4c + 4d= 164
4c + 4(2c)= 164
4c+ 8c= 164
12c= 164
c=13.67
The cost for each CD is $13.67
Answer:
D- 30
Step-by-step explanation:
Total = 50
Percentage= 60%
No : of choose maths = 60/ 100 x 50 = 30
Hope its right!
The first one because they go up by 4 each time thus it is linear.
Hope this helps! :)
