Answer:
correct
Step-by-step explanation:
Imagine a point in the top left quadrant of a graph
when you rotate it 180 degrees it will end up in the bottom right quadrant
The same will apply if you flip on the y axis and the x axis in no given order
X+10=15
Isolate x by subtracting 10 from both sides
x+10-10=15-10
x=5
Final answer: B
Check by plugging the value in
5+10=15
True
10 is 37.037 percent of 27
Answer:
2x = 10
Step-by-step explanation:
7 + 3x = 22
-7 -7
Subtract 7 from both sides (you are trying to get the variable alone, and to do that, you have to get every other number to 0. <em>7 - 7 = 0</em>. BUT, whatever you do, you have to do to both sides.)
3x = 15
/3 /3
Divide both sides by three to get the variable alone.
x = 5
Now, plug in the value of x to the second equation and solve.
2(5) = ? --> 10
