Y=400-10d
If he reads 10 pages a day and there is 400 total pages then you plug in an amount of days (d) to find the total amount of days it takes him to read the book.
Answer:
Probably 7.
Step-by-step explanation:
You may be asking yourself, "Why 7?". That's all.
The <em><u>correct answer</u></em> is:
negative six and thirty-three fortieths
Explanation:
To multiply (2 5/8)(-2 3/5), we first change each mixed number to an improper fraction. To do this, we multiply each whole number by the denominator and add the numerator:
(2*8)+5 = 16+5 = 21; this makes 2 5/8 = 21/8
(2*5)+3 = 10+3 = 13; this makes -2 3/5 = -13/5
This gives us
(21/8)(-13/5) = (21*-13)/(8*5) = -273/40
40 will go into 273 6 times; this gives us the number -6. There is then 270-240 = 33 left over; this gives us 33/40, and a total of -6 33/40.
Coordinates of the center you can find from
x-3=0 and y+5=0
x=3 and y=-5
(3,-5) is the center of the circle.
25 is a square of the radius.
r²=25, so
r=5
Center (3,-5), r=5
So, the answer is D.
Answer:
The answer is 173,595
Step-by-step explanation:
Firstly, you multiply 815 by the first number of 213 which is 3
So:

Then 815 by the second number:

Then 815 by the third number:

Then you add all the numbers, but you have to put a zero to the right of the second product and two zeroes to the third product and so on..
In this case the addition is :
2445+8150+163000 = 173595
