Answer:
infinite solutions
Step-by-step explanation:
-3f + 3f = 0
0=0
This is always true so there are infinite solutions
2/3 (9x - 6)
=2/3(9x) - 2/3(6)
= 6x - 4
answer
B) 6x – 4
Answer:
(a) 75 minutes
(b) 50 minutes
(c) labeling speed = Number of books to label ÷ Time taken to finish labeling them
Step-by-step explanation:
Firstly, she has 750 books to label and she labels 10 books in a minute. Hence, the number of minutes it will take her will equal the number of books divided by the number of books labeled in a minute.
This will be 750/10 = 75 minutes
Secondly, we use the same approach here but the number of books she labeled in a minute is different. Hence we get 750/15 = 50 minutes.
Lastly, the relationship between her labeling speed and the number of minutes is shown as follows.
The speed has a unit of books/minute since it is a rate and this is equal to number of books labeled ÷ Time taken to label them
Answer:
7/8
Step-by-step explanation:
In order to solve this problem, we need to find a common denominator, which is basically the least common multiple of the two denominators.
The two denominators are 8 and 4, and their LCM is 8. So, let's convert all these fractions so that their denominators are 8.
3/8 is already there, so we don't need to touch that.
To make 2/4 have a denominator of 8, we need to multiply the numerator and denominator by 2: (2 * 2)/(4 * 2) = 4/8
Now, we add: (3/8) + (4/8) = 7/8
That's why the answer is 7/8.
Hope this helps!
