Step-by-step explanation:
Answer:
Step-by-step explanation:
-2(2)-1+1(1)-1(-1)
Do multiplication
-4-1+1+1
Now add/subtract
-5+2
-3
58,800.
3600 divided by 9000 is 0.4
147,000 * 0.4 is 58,800
Answer:
no solution
Step-by-step explanation:
Given
(21 - 3a) = 6 - a ( multiply through by 3 to clear the fraction )
21 - 3a = 18 - 3a ( subtract 21 from both sides )
- 3a = - 3 - 3a ( add 3a to both sides )
0 = - 3 ← not possible
This indicates the equation has no solution
Answer:
A
Step-by-step explanation:
The line on the right has equation y = x + 1
The absolute value function always gives a positive value
Thus the equation is y = | x + 1 | → A
