Answer:
$7.65
Step-by-step explanation:
step one:
The total bill was $45.
michelle pays 35% of the total bill
= 35/100*45
=0.35*45
=$15.75
lori pays 48% of the bill
= 48/100*45
=0.48*45
=$21.6
Therefore patti will pay
=45-15.75-21.6
=$7.65
Answer:
30
Step-by-step explanation:
x+50=180(संगत कोन भएकाले )
x=180-50
X=130
अब,
130-100=30
Answer:
x = -
, x = 3
Step-by-step explanation:
Given
(4x - 5)² = 49 ( take the square root of both sides )
4x - 5 = ±
= ± 7 ( add 5 to both sides )
4x = 5 ± 7, thus
4x = 5 - 7 = - 2 ( divide both sides by 4 )
x =
= - 
or
4x = 5 + 7 = 12 ( divide both sides by 4 )
x = 3
As a check
Substitute these values into the left side of the equation and if equal to the right side then they are the solutions.
x = - 
left side = (- 2 - 5)² = (- 7)² = 49 = right side ⇒ solution
x = 3
left side = (12 - 5)² = 7² = 49 = right side ⇒ solution
