4 = 0.4 (3d - 5)
4 = 1.2d - 2
4 + 2 = 1.2d - 2 + 2
6 = 1.2d
6/1.2 = 1.2d/1.2
5 = d

What is the length of a picture frame whose width is 3 inches and whose proportions are the same as as a 9-inch wide by 15-inch

mezya [45]

The answer is 5

Explanation:

The 9 by 15 picture is similar to the 3 by x picture, meaning its the same shape but not the same size.

Since we know what the width is for the first picture we have to get the width of the second picture to equal the same width without changing the shape.

To do that you divide BOTH 9 and 15 by 3

And you get 3 and 5.

Hope this help you understand better.

Eliza reads of her book on Monday. On Tuesday and Wednesday combined,

pickupchik [31]

Answer:

Part A: 204 pages

Part B: 232 pages. 28 pages more.

Step-by-step explanation:

Eliza reads of her book on Monday by $\frac{r}{7}$ pages, where r is the total number of pages in the book.

On Tuesday and Wednesday combined, she reads three times as much as she reads on Monday i.e. $\frac{r}{7} \times 3 = \frac{3r}{7}$ pages.

So, combining Monday, Tuesday and Wednesday she reads $(\frac{r}{7} + \frac{3r}{7}) = \frac{4r}{7}$ number of pages.

Part A: If Eliza's book has a total of 357 pages then combining Monday, Tuesday and Wednesday she reads $\frac{4 \times 357}{7} = 204$ pages.

Part B: If Renee Reads the same fraction of a different book over the same period of time as Eliza, then if Renee's book has a total of 406 pages then combining Monday, Tuesday and Wednesday she reads a total of $\frac{4 \times 406}{7} = 232$ pages.

She reads (232 - 204) = 28 more pages than Eliza. (Answer)
