Answer:
No solution
Infinitely many solutions
One solution
Step-by-step explanation:
The first expression:
-2(3x - 1) = -6x -1
Expand the parentheses;
-6x + 2 = -6x -1
-6x + (-6x) = -1 -2
0 = -3
This problem has no solutions
Second expression:
2(3x-1) = 6x -2
Expand the parentheses;
6x - 2 = 6x -2
6x -6x = -2 + 2
0 = 0
This problem has infinitely many solutions
Third expression:
2(3x - 1) = -6x -2
Expand the parentheses;
6x -2 = -6x - 2
6x + 6x = -2 + 2
12x = 0
x = 0
This equation has only one solution
I just reorder it and range it
First divide bot sides of the formula by 1/2(3.14):-
2A / 3.14 = r^2
r = sqrt (2A/3.14)
Answer:
1-a
2-a
3-b

Answer:
She must work at least 7 hours. All possible values are 7, 8, 9, 10
Step-by-step explanation:
14 - 4 = 10
4($7)=$28
$130-$28=$102
$102÷$15=6.8
$15x7=$105
$105+$28=$133
$15x8=$120
$120+$28=$148
$15x9=$135
$135+$28=$163
$15x10=$150
$150+$28=$178
