Answer:
-x = -2 - 3
Step-by-step explanation:
-x = -2 - 3
-x = -5 then make it positive
x = 5
6.2w = 18.6....divide both sides by 6.2
w = 18.6 / 6.2
w = 3 <==
Answer:
a=8
c=5.5
Step-by-step explanation:
solve simultaneously:
2a + 4c = 38.00
3a + 3c = 40.50
times the first eq. by 3 and the second by 2
6a + 12c = 114
6a +6c = 81
subtract from one another
6a + 12c = 114
-6a +6c = 81
6c = 33
c=5.5
3a + 3x5.5 = 40.50
3a= 24
a=8
Answer:
$162.94
Step-by-step explanation:
Because 20% off of 192.15 = $162.94 and
$153.72 + (6.0%) $9.22 = $162.94
All real numbers would be the domain here
