It’s 30 because you have to do the work in the parentheses first, then you apply it to the rest of the equation.
Answer:
10 books
Step-by-step explanation:
5 shelves and 45 books on each of those shelves equals 225. 235 minus 225 is equal to 10 books.
For this one, use the order of operations to solve it, we called it PERMDAS to remember the steps.
14-6.2 times (-3+ -7)
So do the parenthesis first
-3+-7= -10
now the multiplication
-6.2 times -10= 62
a negative times a negative equal a 62
Now your problem is 14-62
Which equals -48.
So if I did my math and operations correctly, the answer would be B. -48.
Hope this helps!
Answer:
