Answer:
d
Step-by-step explanation:
7x + 2 and 10x - 9 are same- side interior angles and sum to 180° , that is
7x + 2 + 10x - 9 = 180
17x - 7 = 180 ( add 7 to both sides )
17x = 187 ( divide both sides by 17 )
x = 11 → d
Answer:
312 copies
Step-by-step explanation:
100 + 100 = 200
40 + 60 = 100
8 + 4 = 12
200 + 100 + 12 = 312 copies

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.
