How tall is the table?

Mathematics
1 answer:
Solnce55 [7]3 years ago
6 0

Answer:

105cm

Step-by-step explanation:

Call the rat's height r, the cat's height c and the table height t.

The left part says that

(t + c) - (0 + r) = 120 = t + c - r

c - r = 120 - t

Right part says that (t + r) - (0 + c) = 90 = t + r - c

c - r = t - 90

120 - t = t - 90

2t = 210

t = 105

If f is a function, then f(3x)=3f(x)
Delvig [45]
This is false.
The f(3x) means you are multiplying the input 'x' by 3 before plugging into the equation.
3f(x) means you are going to multiply your answer (output) by 3 after you've plugged the input value in and gotten the output.
