8 0

Answer:

It would be 70

Step-by-step explanation:

First step: Divide 156 by 2

156 / 2 = 78

Second Step: The half of 156 is 78. Now we have 78 laptops and desktops, and as we know the question says that "there are 8 more laptops than desktops", the next step to follow is to subtract 8 from 78 (Desktops) and add 8 to the 78 (Laptops).

78 - 8 = 70 Desktops

78 + 8 = 86 Laptops

Hope this helps :)

suppose the number of fiction books is 2/7 times the number of nonfiction books. what would be the ratio of the numbers of nonfi

Elis [28]

Well, the total amount of books is all fiction books and nonfiction books, let's say is "x", total

now, the fiction books are 2:7 or 2/7 to nonfiction

so, if we divide the total "x" by 2+7, or 9, 2 of those quotients go to fiction and 7 of those go to nonfiction

if we divide "x" by 9, a "whole" is 9/9 or (9/9)x or 1x or just "x"

and we know 7 of those 9ths belong to nonfiction, thus

$\bf \begin{array}{clclclll}
\cfrac{2}{9}&+&\cfrac{7}{9}&=&\cfrac{9}{9}\\
\uparrow &&\uparrow &&\uparrow \\
fiction&&nonfiction&&whole
\end{array}\\\\
-----------------------------\\\\
\cfrac{nonfiction}{whole}\implies \cfrac{7}{9}\implies 7:9\impliedby ratio$

Select the term that best describes the statement: The glass is not always half full. a. conjunction

vlada-n [284]

Answer:

c. negation

Step-by-step explanation:

A conjunction is two statements joined by "and"; that does not fit this statement, so it is not a conjunction.

A disjunction is two statements joined by "or"; that does not fit this statement, so it is not a disjunction.

A conditional is an "if-then" statement; that does not fit this statement, so it is not a conditional.

This is a negation; the word "not" negates "the glass is always half full."
