Answer:
10x-15
Step-by-step explanation:
First, do Abbey. Abbey= 5 hrs less than 3 Emily.
Nathan spends twice as much as Abbey. Then you get 3x (Emily is x) -5 +x (for Emily) +6x - 10 (for Nathan. Add those. You get 3x+x+6x-5-10. I hope this is correct.
Step-by-step explanation:
the true statemnts underneath and are in bold letters
-.For all nonempty sets A, B, C, D, if A x B = C x D, then A = C and B = D.
This property is true
-The cartesian product has a cancellation property, i.e. if A x B = A x C for some sets A, B, C and A nonempty, then B = C.
This property is true
- If A={1,2} and B={3} then A x B ={ (1,3), (2,3) }.
if we have 2 non empty sets a and b if we want to get their cartesian product, it is defined as the set of all ordered pairs from a and b
we have A x B to be{(1,3)(2,3)}
therefore this is also true
The answer is C I’m pretty sure, it makes the most sense
