X + 3 = 2x +5
-x -5 = -x - 5
x = -2
The whole number part of a decimal stays the same, and stays to the left of the decimal point. You have to transform the fraction into a decimal by dividing the numerator (number on the top) by the denominator (number on the bottom). If you divide 3 / 4 then you get 0.75. When you add this to the whole number part that you already know, then you get 43.75.
X + 11 + 8x = 29. We need to solve for x.
First, on the left side, you have "x" and "8x": You can always add 2 numbers with the same variable, so you have 1 number: x + 8x = 1x + 8x = (1+8)x = 9x
So we get:
9x + 11 = 29
Now subtract 11 from both sides (You can't do any operation if you don't do it both sides), so you can get the variable alone on the left side, and the numbers on the right side:
9x + 11 = 29
9x + 11 - 11 = 29 - 11
9x = 18
Now divide both sides by 9, so you can transform the coefficient of x to one, and have the numeric value of x on the right side:
9x = 18
(9x)/9 = 18/9
x = 2
So x+11+8x = 29 for x = 2.
You can recheck your answer (very important):
x + 11 + 8x = 2 + 11 + 8*2 = 2 + 11 + 16 = 13 + 16 = 29
The answer has been approved.
Hope this Helps! :)
Uhh... what are the options?
Here's some possible ones:
0.2
1/5
Answer:
$16,000?
Step-by-step explanation:
375 times 36 is 13500
Add 2500
and you have 1600
thats my guess
