You use the order of operations. So in you start with multiplication. 8*7= 56. Then that would leave 56-4. 56-4 is 52.
Is this meant to be a question? If so, what are you asking. The all time low for Dallas would be -3 degrees if that's what you want to know.
There are 2001 items in that set.
So n(A) = 2001
We can individually count them all out, which is very slow and tedious, or we can use the formula
n-m+1
where,
m = starting value
n = ending value
In this case,
m = 0
n = 2000
So,
n-m+1 = 2000-0+1 = 2001
This formula only works if we increase the number by 1 each time (eg: 6, 7, 8, etc)
Answer:

Answer:
11 calls
Step-by-step explanation:
She has already spent 42 min. Also she wants to talk for 2 min per call. We can change calls on x. So, only 2x min for her calls left.
42 + 2x = 64
2x = 64 - 42
2x= 22
x=11
Answer: 11 calls
