850.

68,750 = 350(75) + 50x
68, 750 = 26,250 + 50x
                -26250
42,500 = 50x / 50
850 = x

Franco is reading a book with 482 pages he reads 30 pages each night. how many pages will he read in 7 nights? show your work
Sergeu [11.5K]
The number of pages in the book is actually irrelevant.

Franco reads 30 pages in 1 night. To find how many pages he reads in 7 nights, just multiply by 7.

30*7=210

Franco reads 210 pages in 7 nights.


Solving with Equivalent Ratios:

The ratio of pages he reads per night is 30:1. We need to figure out the ratio <em>x</em>:7, where the variable <em>x</em> is the number of pages he reads in 7 nights.

30:1=<em>x</em>:7

To find x we need to see the similarity between both ratios. This is found by dividing two of the equal sides, here it would be 7 and 1.

7/1=7

This means that the second ratio is 7 times the first ration. To find <em>x</em>, just multiply 30 by 7.

30*7=210

Franco reads 210 pages every 7 nights.

Determine if the sides form a right triangle.
Law Incorporation [45]

Answer:

Yes, it's a right-angle triangle

Step-by-step explanation:

3 root 2 is 4.24

3 root 3 is 5.2

3 root 5 is 6.71

3 root 5 is the longest side, so must be the hypotenuse.

a^2 + b^2 = c^2

(3 root 3)^2 + (3 root 2)^2 = c^2

45 = c^2

Square root both sides

C = root 45

( simplified to C= 3 root 5)

Thus, it is a right-angle triangle.

(Root means a square root)

Hope this helps!

Add the following polynomials, then place the answer in the proper location on the grid. Write answer in descending powers of x.
CaHeK987 [17]

Answer:

-x^5+3x^4+16x^3+7x^2-3x+6

Step-by-step explanation:

Given polynomials are:

x^5-4x^4+7x^3+8, 9x^3+7x^2-10 and -2x^5+7x^4-3x+8

Now we need to add the given polynomials, then place the answer in the proper location on the grid. Also we need to write answer in descending powers of x.

So let's add them by combining like terms:

x^5-4x^4+7x^3+8+9x^3+7x^2-10-2x^5+7x^4-3x+8

-x^5+3x^4+16x^3+7x^2-3x+6

Hence final answer in descending order is -x^5+3x^4+16x^3+7x^2-3x+6
