Sophia wrote 260,880 as (2 times 100,000)+(6 times 10,000)+(8 times 100). what error did sophia make

260,880 as (2 times 100,000)+(6 times 10,000)+(8 times 100).

here Sophia must consider 80 as 8 times 10

so that complete expression becomes

260,880 = (2 times 100,000)+(6 times 10,000)+(8 times 100)+(8 times 10)

answer: 370

step-by-step explanation:

remember use pemdas! there are no parentheses or exponents so lets move onto the first part of the equation: multiplication and division. first, lets break the first part of the equation up into something easier using the distributive property. 28 * 12= (20 *12) + (8*12) you know that 20*12 is 240 and 8*12 is 96. add them and you get 336. then, lets solve the last part of the equation (the last part of pemdas is addition and subtraction). 336 plus 34 is 370. hope this !

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
