Combine like terms. 4b +5b = 9b. Isolate the variable. Divide both sides by 9.
9b = 44
/9 /9
b = 4 8/9 or 4.88888888...
I'm not sure why you'd get a problem like that, but anyways, I hope this was helpful.
$.20* 12 (inches to feet conversion) * 5.25' = $12.60
I hope this was helpful.
Please be more specific.
The base number must be between 1 and 10. The number of times you move the decimal place to make the number between 1 and 10 is the power of 10 that you will have, and the direction you went determines whethere the power of 10 is negative or positive.
Move the decimal point 3 times to the right, so
1.5 x 10-3
4/7 k = 3/4
Divide both sides by 4/7 to get k all by itself. So multiply both sides by the reciprocal, 7/4.
*7/4 *7/4
k = 21/16 or 1.3125
Hope this was helpful.
Your question is too vague.
Specifically what do you not understand about using negative numbers?
To convert a percent to a decimal, divide by 100%.
35%/100% = 0.35
Then divide normally.
27.5/0.35 = 78.571428571428...
12 +5b = 3(b+8)
12 +5b = 3b +24
-12 -12
5b = 3b + 12
-3b -3b
2b = 12
/2 /2
b=6
I hope this was helpful :)
The result is too big for the calculator to display, so it says infinity.
"of" means multiply.
14% = 0.14 (because 14% /100% = 0.14)
Knowing what you now know, you can plug in 0.14 * 471 into the the calculator on the home page of this website.
