5x + 3 = 3x + 11
• first put all the x-values on one side and the rest on the other
Remember: when the number moves to the other side of the equal sign the sign (+ OR - switches. For ex: the 3 on the left becomes negative when moved to the right side of the equal sign)
5x - 3x = 11 - 3
• subtract left and right sides separately
2x = 8
• divide both sides by 2 to solve for x
2x/2 = 8/2
x = 4 (final answer)
Answer:
its answer is 17 first find p and q value then use x2-x1 y2-y1 formula
Answer:
40
Step-by-step explanation:
let the unknown be y (x is used as times(multiplication) )
(y-17)x-6=-138
add /-6 to both sides
y-17x-6/-6=-138/-6
y-17=23
make y independent/add 17 to both sides
y-17+17=23+17
y=40
or in an easier way
-138/-6 =23
23+17=40
simply reversing the question to get the answer
Rounding is based off of the digit following the place we are rounding to
there are several possibilities for a number when we are "reverse rounding"
the original value could have been
3.73... and was rounded up
or
it could have been 3.74 but rounded down
all we do is identify the range of possible numbers and pick one as our answer
the lowest possible value would be 3.735...
the highest possible value would be 3.744...
so just pick any number falling within that range
