Answer:

For this problem, just apply the laws of exponents. When dividing variable with the same base, just subtract their exponents. Hence, x^-6 divided by x^2 would be x^-8. Then, multiply the exponent with 3, becoming x^-24. Or, in reciprocal form, 1/x^24.

Solve y-12/25=3 1/5. What number is y? A. 3 1/5 B. 3 17/25 C. 3 7/25 D. 4 17/25

kicyunya [14]

Answer:

Option c) y= $3\frac{17}{25}$ is correct

The value of y is 3 $\frac{17}{25}$

Step-by-step explanation:

Given equation is

$y-\frac{12}{25}=3\frac{1}{5}$

To solve the given equation for y

$y-\frac{12}{25}=3\frac{1}{5}$

$y-\frac{12}{25}=\frac{16}{5}$ (converting mixed fraction to normal fraction )

$y-\frac{16}{5}=\frac{12}{25}$

$y-\frac{(16\times 5)+12}{25}$ (taking LCM 25 )

$=\frac{80+12}{25}$ (adding the terms )

$y=\frac{92}{25}$ (now convert fraction into mixed fraction )

Therefore y= $3\frac{17}{25}$

Option c) y= $3\frac{17}{25}$ is correct

The value of y is 3 $\frac{17}{25}$

xialoli was estimating the difference between two positive numbers x and y (where x>y). First she rounded x up by a small amo

AleksandrR [38]

Remark

This is an excellent question. Estimation is a powerful skill to have. People should always shop using estimates. Try it to see what happens.

x = 11.7 which rounds up to which we will call x1 and that is 12

y = 6.03 which round down to 6 which we will call y1 and that is 6

Now x - y = 5.67

If you do the rounded subtraction x1 - y1 = 12 - 6 = 6

The estimate is not zero. D is not correct.

There is enough information E is not the answer.

B is wrong, her estimate is larger than x - y

C is wrong the two subtractions are not equal.

A is correct and always will be no matter what numbers are chosen
