Y varies directly with x means y=kx, where k is constant. In this case Venus is y and Mercury is x. Find k by plugging in the first two values,
k= y/x
k= 108/45 = 2.4
Then using the second value for Mercury
y = kx
y = (2.4)(35)
y = 84
The object weighs 84 kg

Step-by-step explanation:
Emery has solved it incorrectly;
x = 100
Answer:
42
Step-by-step explanation:
let's make the missing number x
multiply 3 on both sides to get rid of the fraction, 41 × 3 = 123
simplify the right side, 48 + 33 = 81
subtract 81 on both sides
The range would be $14.
To find the range, you would take the highest value and subtract it by the lowest value:
29 - 43 =
14
Hope this helped! :)
I believe the answer for the first question is A. but not 100% sure, it's the only one I can figure out to be right.
The answer for the second question is C. 90% of 30 is 27.
I hope this helps.
