Answer:
About 300 dollars
Step-by-step explanation:
THe best estimate for week one is 300, because 96 rounds to 100, and 100 * 3 equals 300.
The best estimate for week 2 is 600, because 204 rounds to 200, and 200 * 3 equals 600.
600 - 300 = 300, therefore the difference is about 300 dollars.
Hope this helps!
Answer:
Step-by-step explanation:
2y = -x +9
3x - 6y = -15
The solution is the value of x and y that will make the two equations true in the same time.
3x-6y = -15; divide both sides by 3
x-2y = -5; substitute 2y for -x+9 because the first equation tell us they are equal
x-(-x+9) = -5; open parenthesis
x+x-9 = -5 ; add 9 to both sides and combine like terms
2x = -5 +9; 2x = 4; divide both sides by 2
x= 2
Substitute x for 2
2y = -x+9 ; 2y = -2 +9 ; 2y = 7; y = 7/2 = 3.5
Solution is (2, 3.5)
