Answer: .9

Step-by-step explanation:

When writing fractions to a decimal you divide the numerator and the denominator. For Example: 7/10 into a decimal divide 7 and 10. The decimal point wil be behind 7.

Now move the decimal point to the left.

Before: 7.

After: .7

Remember: When multiplying decimals always move to the RIGHT. When dividing decimals move to the LEFT.

Factorise:<br> (x - 2y)2 - 12(x - 2y) + 32

Vedmedyk [2.9K]

Hi there.

The answer is (x-2y-8)(x-2y-4)

Explanation:

$(x - 2y)^{2} - 12(x - 2y) + 32$

Let (x-2y) = x

${x}^{2} - 12x + 32$

Then factor the quadratic polynomial by 2 brackets factoring.

$(x - 8)(x - 4)$

Then convert x to (x-2y)

$(x - 2y - 8)(x - 2y - 4)$

VashaNatasha [74]

$Method\ \#1\\\\\begin{array}{ccc}31&-&40\%\\x&-&100\%\end{array}\ \ \ \ |cross\ multiply\\\\\\40x=31\cdot100\ \ \ \ |divide\ both\ sides\ by\ 40\\\\x=\frac{3100}{40}\\\\\boxed{x=77.5}$

$Method\ \#2\\\\p\%=\frac{p}{100}\to40\%=\frac{40}{100}=0.40=0.4\\\\x-the\ number\\\\40\%\ of\ the\ number\ is\ 31:\\\\0.4x=31\ \ \ \ |divide\ both\ sides\ by\ 0.4\\\boxed{x=77.5}$
