Answer: 96/45
Step-by-step explanation: The answer is 96/12 because to divide fractions you reciprocate the second fraction and turn it into a multiplication problem.
8 times 12 = 96
9 times 5 = 45
96/45
Answer:
2
Step-by-step explanation:
15x + 16 = 48 - x
16x = 32
x = 2
Plug two in and it fits right in :)
Answer:
40
Step-by-step explanation:
8:3 So divide 15 by 3. you get 5. Multiply 5 by 8 and you get 40
Answer:
There are infinite solutions that solve the system
Step-by-step explanation:
- The solution can be expressed as
(there are infinite solutions that solve the system). This results from rearranging terms in the first or second equation.
- This is because the first equation is a linear combination of the second one (this is, the first equation equals (-1) times the second equation). This means that the second equation does not add any information about x and y: it says exactly the same as the first equation about the relationship between x and y.
- Then, in terms of solving the system, you have one unique expression (not repeated) that shows the relationship between y and x. This means that, any pair of (x,y) that meet the requirements expressed by
, will solve the system. Then we have infinite solutions.
