Answer:
What type of problem are you asking? Math, English, Computer, etc.
Step-by-step explanation:
First put a bubble around 5x-7. Now you plug that into the problem. -3x-2
(5x-7)=12. now times the -2 by 5x which is -10x. and then times the -2 by -7 which is 14. so now you have -3x-10x+14=-12. add the -3x and -10x. -13x. Add the 14 over. -13x=2. Now dived by -13, which gives us x=-0.15
Now you take that a plug it into the -3x-2y=-12. So that it looks like this -3(-0.15)-2y=-12
Now times the -3 by -0.15 to give us 20 -2y=-12. Now 'kill' the 20, so that it looks like this -2y=-32. Now you divide by -2 and get y=16.
Now your ordered pair is (-0.15,16)
61 = 3b + 7
3b + 7 = 61
3b = 61 - 7
3b = 54
b = 54/3
b = 18.
Answer:
2(n+1)+2
You start with two greens and two columns of two orange squares while adding two orange squares each time. So, the bolded part is the green squares that stay the same. The 2(n+1) represents the two orange columns that increase by one block on each side per image.
