Answer:
a) 3 b) 5 c) 7 d) 9
Step-by-step explanation:
For this, you want to replace x in the equation y=x+5 with each of the values listed.
For the first one, -2, the equation becomes y=-2+5, which is solved to y=3.
For the second one, 0, the equation becomes y=0+5, which is solved to y=5.
For the third one, 2, the equation becomes y=2+5, which is solved to y=7.
For the last one, 4, the equation becomes y=4+5, which is solved to y=9.

Answer:
7 minutes
Step-by-step explanation:
okay so lets make blocks = x and neighborhood = y
2x + y =10
2x + 4y = 31
multiply the top equation by -1 so we can single out y
-2x - y = -10
2x + 4y = 31
combine the two equations
3y = 21
since the x's have canceled each other out, just divide both sides by 3 to get a single y
y = 7
