Answer:

Darius is correct

Step-by-step explanation:

Darius reads \frac{2}{10} of his book in 3 days

In 1 day, he reads \frac{2}{10} \div 3 of the book.

Therefore in 15 days,  He reads

(\frac{2}{10} \div 3) X 15=\frac{2X15}{10X3}=\frac{30}{30}=1

which is the whole of the book.

Which equation has a graph of 7x=14y-8
masha68 [24]
You could re-write this to make it into an equation, you want to isolate the y, for a slope-intercept form. So you +8 to the other side; so it would be 7x+8=14y, then divide it by 14. And your equation would be y=4/7+x/2.

kakasveta [241]
<h2>Hope this helps!</h2>

Answer:

$68.32

Step-by-step explanation:

Is 9.76 = x

And the value needed is 8 * this amount, then it can be shown with 8x

8x = 9.76 * 8

8x = 78.08

So the total price is $78.08

To find the money needed, simply subtract the saved money from this amount:

78.08 - 9.76 = 68.32

So she needs $68.32!

The vertices of AABC are A(-6, -7), B(-3,-10) and
LenaWriter [7]

Answer:

A, but try the rest of the points!

Step-by-step explanation:

I assume AABC means triangle ABC

Just do the operation to each point.  so A is (-6, -7)  (x - 2. y - 7) is telling you subtract 2 from -6 and 7 from -7 or in other words it changes from  (-6, -7)  to (-6 - 2. -7 - 7) = (-8, -14)

Only one answer has that point for A', but you should really really really try the rest.

Negative two and one-third minus negative ten and one-sixth
zhenek [66]

Answer:

7 and 5/6.

Seven and five-sixths.

Step-by-step explanation:

-2 and 1/3  = -6/3 and 1/3 = -7/3

-10 and 1/6 = -60/6 and 1/6 = -61/6

(-7/3) - (-61/6)

= (-14/6) + (61/6)

= 47/6

= 7 and 5/6.

Hope this helps!
