The figure RQTS is a clockwise rotation of figure DEFC, then:
The image of CD is
Answer: Option C. RS
You must get the like terms on the correct sides, so here is how to solve it:
First subtract 5x from both sides: 3x+4=-11
Then subtract 4 from both sides: 3x=-15
Finally divide by 3: x=-5
Answer:
300
Step-by-step explanation:
That would be 2.25 / 0.0075
= 300
5 (x-2y)=20
x-2y=20/5
x-2y =4
-2y=4-x
y=- 4-x/2
ans -4-x/2
Answer:
4376
Step-by-step explanation:
8, −24, 72, -216, 648, -1944, 5832
Multiply the next number by -3
8 x -3 = -24
-24 x -3 = 72
72 x -3 = -216
-216 x -3 = 648
648 x -3 = -1944
-1944 x -3 = 5832
adding all 7 numbers
8 + (−24)+72 + (-216)+648+ (-1944)+5832 = 4376
