When is the sum of two integers equal to zero? Explain.
Answer:
Rule: The sum of any integer and its opposite is equal to zero. Summary: Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.

if Afsheen can read 39 pages of a book in half an hour how much will it take her to finish the book that is 1287 pages
We are given:
Afsheen can read 39 pages in 30 minutes
Time taken by Afsheen to read 1287 pages:
Time taken to read 1 page:
Time taken to read 1 page = time taken to read 39 pages / 39
Time taken to read 1 page = 30 minutes / 39
Time taken to read 1 page = 0.77 minutes
Time taken to read 1287 pages:
Time taken to read 1287 pages = Time taken to read 1 page * 1287
Time taken to read 1287 pages = 0.77 * 1287
Time taken to read 1287 pages = 991 minutes OR 16.52 hours (Approx)
Answer:
in 1 hour = 2×39= 78 pages
so 1287 pages= 1287÷78= 16.5 hours
Step-by-step explanation:
it takes 16. 5 hours that means 16 hours 30 min

Find the ratio a:b if it is given that ... a+3b/5=a-2b/2. HELP RIGHT NOW PLS
By simplifying the given equation, we can see that the ratio a:b is:
8:1
How to find the ratio a:b?
We start with the equation:
(a + 3b)/5 = (a - 2b)/2
The first thing we need to isolate each variable in one side of the equation.
(a + 3b)/5 = (a - 2b)/2
2*(a + 3b) = 5*(a - 2b)
2a + 6b = 5a - 10b
6b + 10b = 5a - 2a
16b = 2a
So, 16 times b is equal to 2a
We can write this as:
b/2 = a/16
b = a/8
Then the ratio a to b is:
8:1

How do you solve 7,124 ÷ 26 using standard algorithm?
Answer:
274
Step-by-step explanation:
The standard algorithm of multiplication is based on the principle that you already know: multiplying in parts (partial products): simply multiply ones and tens separately, and add.
However, in the standard way the adding is done at the same time as multiplying. The calculation looks more compact and takes less space than the “easy way to multiply” you have learned.(i really think this is correct but I am so so sooo sorry if it's not!!!!)
Which expression is equivalent to -51-(-60)
Answer:

Step-by-step explanation:
When subtracting with negative numbers use the "keep, change opposite" skill. Keep your first number which in this case, is -51, then change the subtraction sign to addition and lastly change the sign of your last digit which is (-60) so opposite of that just 60.

Answer:
x=19
Step-by-step explanation:
4x-3x-12=7
x-12=7
x=7+12
x=19
Answer:
x=19
Step-by-step explanation:
first you would distribute the -3 to the x and the 4 which would give you
4x-3x-12=7
next you would combine like terms (there's always an invisible 1 one front of a variable)
x-12=7
then to get the variable by itself you would add 12 on each side
x=19
