Write and solve an equation of ratios:
x 9
---- = ----
16 x
Cross mult., we get x^2 = (16)(9)
Taking the sqrt of both sides, we get x = plus or minus (4)(3), or
x= plus or minus 12
Since x is measure of distance here, omit the -12 result. x = +12 units
Answer:
14/11
Step-by-step explanation:
A rational number times a rational number is rational
A rational number is written as a/b
14/11 * 1/2 = 7/11
This is rational
This one you can do by multiplying the number by ten, getting 1.666, or 1+0.66. 0.66 is easy to put into a fraction form as 2/3. add the other 3/3 from the whole 1 to get 5/3. From here you either divide by 10 or multiply by 1/10, as KCF will do that anyways if you divide to get 5/30, or 1/6.
Answer: 31 cents
Step-by-step explanation: Since sales tax is 6%, in decimals, that is 0.06. Then you multiply the total of the bill by the tax amount to get how much she will be paying in tax.
5.20 x 0.06 = 0.312
Then you round to the nearest hundreth since you can't have a fraction of a cent to get 0.31
First we want to join the denominators together
Then we want to gather all like terms
And lastly simplify
Answer: 2x + 11
---------
