Step-by-step explanation:
Answer:
Assuming you're solving for <em>n</em>, 1. n=-1 2. n=-1.6
Step-by-step explanation:
1. -5(2-5n)+6=-5n-34-2
Distributive Property
-10+25n+6=-5n-32-2
Add Like Terms
-4+25n=-5n-34
Subtract -4
25n=-5n-30
Subtract -5n
30n=-30
Divide by 30
n=-1
2. -5(2-5n)+6=-5n-34-20
Distributive Property
-10+25n+6=-5n-32-20
Add Like Terms
-4+25n=-5n-52
Subtract -4
25n=-5n-48
Subtract -5n
30n=-48
Divide by 30
n=-1.6
Compatible numbers is used to find estimate to a sum. The numbers are chosen because its 'simplicity' when they are multiplied, divided, added or subtracted.
Estimate one:
We can decrease the value 1322 to 1320 and 18 to 15
Then do the sum = 1320÷15 = 88
This estimate is not far from the actual answer 1322÷18 = 73.44..
Estimate two:
We can increase 1322 to 1330 and 18 to 20
Then do the sum 1330÷20=66.50
This estimate is also not far from the actual answer 73.44...
