A+b= 17
a-b=3
a=10
b=7
That is the answer
Answer:
17.5
Step-by-step explanation:
Given that the variables x and y have a proportional relationship.
i.e. y is directly proportional to x or can be written as
y = mx where m is the constant of proportionality.
When x =2, y =7
Substitute this to get the value of m.
7 =2m or m = 3.5
Thus the relationship between x and y is
y = 3.5x
So when x=5, y = 3.5(5) = 17.5
Answer:
a
Step-by-step explanation:
5 is greater than 4 while the rest aren't
Answer:
Final grade: 93.9%
Step-by-step explanation:
The weights are as follows: 0.25, 0.10, 0.30 and 0.35. Note that these add up to the whole, that is, to 1.00.
Then the final grade is:
0.25(94) + 0.10(99) + 0.30(92) + 0.35(94) = 93.9
