Answer:

a = -2

b = 7

Step-by-step explanation:

5a+3b=11

-2a+3=b

substitute for b:

5a + 3(-2a + 3) = 11

5a -6a + 9 = 11

-a = 2

a = -2

b = 7

How do you estimate the sum of 36795 and 14467
USPshnik [31]
To estimate the sum of these two numbers, we shall round them to the nearest 5,000, and then add the sum of those numbers.

36,795 rounded to the nearest 5,000 = 35,000
14,467 rounded to the nearest 5,000 = 15,000

15,000+35,000= 50,000

Therefore, an estimate for the sum of 36795 and 14467 is approximately 50,000.
