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?
what is the value of X in X/5 = 45 and why?
What do think will happen if you multiply both sides by 5? Try and see.
negative 3.5 squared=-3.5^2=12.25
t=4.86988015815
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

10% off £31=1 - .10=.90 left X 31=27.9 pounds
Look it up in your Math book!!!.
what is x with exponent 2 equals 300
x^2=300, take the square root of both sides,
x=sqrt(300)=17.32(rounded), so that 17.32^2=300(rounded)
If you know how to SWEAR, then you should be able to figure it out!!!!. Maybe, that will humble you.
please show steps
16^1/4 simplified
Assuming D is a variable:
d + 5 /10 =2
d+ 1/2 = 2
d = 3/2 = 1.5
ok?
Thanks, Melody, that'll help me a lot in the future! :)
(From, the person who asked this question)
sin(sin^-1(5pi/3))
5pi/3 is a trig ratio not an angle and it is approximately equal to 5.2
Now sine of any angle must be between -1 and 1 so sin^-1(5pi/3) is undefined.
So this question makes no sense. The answer is undefined.
6/9-1/4=15/36=5/12
5*5= 25
First find out how many people can eat from 1 pizza pie. So you divide 60 from 5 and get 12. Next multiply 12 times 7 and you get 84 people
287
6/9-1/4=24/36-9/36=15/36
30% off 161.99 = first you must find 30% of 161.99 then subtract the product from 161.99
.30 * 161.99 = 48.597
161.99-48.597= 113.393
