Because you're trying to make them congruent, equal the two expressions to each other.
So, for #10 you would equal them so it would look like this.
2x+2=5x-19
Then you would just go ahead and simplify
2x+2=5x-19
-2x -2x
---------------
2= 3x -19
+19 +19
---------------
21=3x
--- ----
3 3
x=7
This means that x should be 7. You can check this just by plugging it in
2x+2
2(7)+2 = 16
5x-19
5(7)-19= 16
Same with #11.
x+8=3x-14
-x -x
--------------
8=2x-14
+14 +14
--------------
22=2x
--- ----
2 2
x=11
Check.
x+8
11+8= 19
3x-14
3(11) - 14 = 19
The answers D, the explanation is that it’s basically common sense just look for the same numbers and make it make sense :)
5 million x 3% = 150,000
1 Year = 5,150,000
5.15 million x 3% = 154,500
2 Years = 5,304,500
5,304,500 x 3% = 159,135
3 Years = 5,463,635
5,463,635 x 3% = 163,909.05
4 Years = 5,627,544.05
5,627,544.05 x 3% = 168,826.322
5 Years = 5,796,370.37
After 5 years, the population will be 5,796,370.37
Answer:
ac is parallel to df because it doesn't intersect with each other
