Step-by-step explanation:

62500 - 56100 = 6400 - number of retrivers u lost per year.
Answer need to be lower then 62,5 and 56,1 thousand so no (A) and not (D)
Number is reduce by 6400 and starting amount was 62500, 2 zeros and end must stay there in answer so not (B)
Then it must be (C)
Or u can calculate 62500 - 9*6400 = 4900
Step 1
Multiplication property of equality
Multiplying the first equation by 5 and the second equation by 7
Step 2
Addition property of equality
Adding the two equations you get 31a =217
step 3
Division property of equality
Dividing both sides of the above equation by 31 to get the value of a
step 4
Substitution property of equality
Substituting a with 7 in the first equation
step 5
Simplify
simplifying the equation got above
step 6
Using associative property of addition by taking 14 to the other side of the equation.
step 7
Division property of equality
Dividing both side of the equation by 7 to get the value of b
Step 1) Add up the three given angles: 125+109+83 = 317
Step 2) Subtract the result (found in step one) from 360
360 - 317 = 43
The reason for the 360 is because for any four-sided polygon, the angles always add up to 360 degrees.
The answer is 43
Part B is saying to equal the both equations, so
5x + 2 = 5x + 5
Take a look, we have the same multiplicative to our variable, but we have different sums, so, if we just say x = 0 we wil have:
5.0 + 2 = 5.0 + 5
0 + 2 = 0 + 5
2 = 5
And of course it's not true, 2 will never be equal to 5, so we can say there's no solution for x.
Another way to see this is:
5x + 2 = 5x + 5
5x - 5x = 5 - 2
0 = 3
0 of couse isn't equal to 3.
