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
Answer:
S: 24x - 72
S and T are not equivalent for any value of x
Step-by-step explanation:
S: 4(6x-18) = 4 * 6x - 4 * 18 = 24x - 72
S and T are not equivalent for any value of x, x+1 S: 24 - 72 = - 48 T: 24 - 18 = 6
Answer:
Beto and Mark
Step-by-step explanation:
When you simplify Beto's equation, you get 0=5 which is inncorrect. 5 does not equal 0 so there are no solutions. When you simplify Mark's equation, you get 6=2 which is also inncorrect. 6 can not equal 2. If you solve the other 2 equations you get answers that can work.
