Answer:
Step-by-step explanation:
a) 60 = 50x
x = 60 / 50 = 1.20
1.20(100) = 120%
b 50 = 60x
x = 50/60 = 0.83333....
0.83333(100) = 83.333... % or 83⅓%
Answer:
20
Step-by-step explanation:
If you know algebra here is the answer:
x = number of hours needed to work
10x=$200
10/10=200/10
x=20
Otherwise just do 200/10 to find your answer.
Answer:
If the sequence has a common difference, it's arithmetic. If it's got a common ratio, you can bet it's geometric
Answer:
Step-by-step explanation:
x = smaller number, y = bigger number
7x + 2y = 635
7y - 2x = 871....rearrange...-2x + 7y = 871
7x + 2y = 635....multiply by 2
-2x + 7y = 871...multiply by 7
----------------------------------
14x + 4y = 1270 (result of multiplying by 2)
-14x + 49y = 6097 (result of multiplying by 7)
--------------------------------add
53y = 7367
y = 7367/53
y = 139
7x + 2y = 635
7x + 2(139) = 635
7x + 278 = 635
7x = 635 - 278
7x = 357
x = 357/7
x = 51
solution : x = 51 and y = 139 or (51,139)
The X can be in a range number from -5 to -2.
