3 0
3x + 3y = 27
3x - 3y = -11
------------------add
6x = 16
x = 16/6 which reduces to 8/3

3x + 3y = 27
3(8/3) + 3y = 27
8 + 3y = 27
3y = 27 - 8
3y = 19
y = 19/3

solution is (8/3, 19/3)

Complete the solution of the equation. find the value of y when x equals -6. -4x + y = 29
Bingel [31]

Answer:

5

Step-by-step explanation:

x = -6

-4x + y = 29

substitute x = -6 in -4x + y =29

-4(-6) + y = 29

24 + y = 29

subtract 24 from both sides

24 - 24 + y = 29 - 24

y = 5

Scott divides some 4-digit numbers by 1000. His answer is a decimal every time. Scott says,if you divide a 4-digit number number
Ghella [55]

Answer:

1000, 2000, 3000, .... etc are the 4-digit numbers which when divided by 1000, give whole number answer.

Step-by-step explanation:

Scott divides some 4- digit numbers by 1000 and his answer is a decimal every time.  

From this Scott has concluded that if you divide a 4-digit number by 1000, then the answer will never be a whole number.

I think Scott is wrong and the reason is that if we try to divide those 4-digit numbers which are multiples of 1000, i.e. 1000, 2000, 3000, 4000, ... etc. with 1000 then only you will get a whole number answer. (Answer)
