Answer:
27
Step-by-step explanation:
n+6+2n+3=90, 3n=81, n=27
First one,
You add -7 to the pattern.
5, -2, -9, -16.
50 times is going to be -350. But it starts at 5, so you add 5 to -350... so it should be -345?
second if the top is 7.1 and the bottom is 3.9. The average is (7.1+3.9)/2.
11/2 = 5.5
Add 10 to each number in the pattern.
-7, 3, 13, 23.
110 times should be 1100, but it starts at -7, so you add -7 to 1100. 1093. :)
Answer: 250 hamburgers
Step-by-step explanation: x= hamburgers
If there are 72 more cheeseburgers than hamburgers there are:
x+72
The number of cheeseburgers and hamburgers=572 so:
572= x+72+x
Then solve
572=x+72+x
572=2x+72
-72 -72
———————
500=2x
500/2=2x/2
250=x
The common difference is 5 each time. Take for example -9 and -4 it’s goes up 5, and then 1 and 6 it goes up five and so on,hope this helped!
