0.3(10-5x)=31.5(8x+9)

Mathematics
1 answer:
salantis [7]3 years ago
7 0

Answer:

<h2>x = - 1.106</h2>

Step-by-step explanation:

0.3(10-5x)=31.5(8x+9)

<u>Expand the terms in the bracket</u>

That's

3 - 1.5x = 252x + 283.5

<u>Subtract 3 from both sides</u>

3-3 - 1.5x = 252x + 283.5 - 3

-1.5x = 252x + 280.5

<u>Subtract 252x from both sides</u>

That's

- 1.5x - 252x = 252x - 252x + 280.5

- 253.5x = 280.5

<u>Divide both sides by -253.5</u>

We have the final answer as

x = - 1.106

Hope this helps you

Inessa [10]
Since the plot of "The Wife of Bath's Tale" has at its heart a loathly lady who shape-shifts into a beautiful, young damsel, we might expect appearances to be important here. And they are, just not for the reason you might think. For instead of this being a tale about how a knight learns to appreciate people for what's on the inside and that outer appearances don't matter, it's a tale about how a knight learns to give up sovereignty to his wife. That sovereignty includes power over the body. The loathly lady's physical appearance becomes an important symbol of that body, so that, at the end of the tale, when she offers her husband a choice about how he wants her to look, she's in essence offering him control of her body. He grants this control back to her, thus proving his understanding of the doctrine of women's sovereignty in marriage. Medieval stories don't necessarily go in for the whole 'appearances don't mean anything' maxim anyway, as we've seen in the "General Prologue<span>."</span>

Explain how you would convert a measurement given in ounces in pints
Tom [10]

Answer:

It is known that 1 pint equals 16 ounces

Step-by-step explanation:

It is known that 1 pint equals 16 ounces. Then we use this data to transform a number of ounces into pints.

Suppose we have x ounces. We want to know how many pints are these x ounces. Then we perform the following operation

x\ ounces*\frac{1\ pint}{16\ ounces}=z\ pints

Where z pints is the amount equivalent to x ounces
