Answer:
$199.31
Step-by-step explanation:
To find the answer, you have to do 190 x 4.9%, which is $9.31. You can also do 190 x 4 9/10, which you need to make the 4 9/10 an improper fraction, which is 49/10. 190 x 49/10 is 9.31. 190 + 9.31 is the answer ($199.31)
Percent means parts out of 100
140%=140/100=1.4
'of' means multiply
'is' means =
140% of what is 48 means
1.4 times what=48
divide both sides by 1.4
what=34.285714285714285714285714...
Answer:
B
Step-by-step explanation:
Given
4x² - 72x = 0 ← factor out 4 from each term
4(x² - 18x) = 0
To complete the square
add/subtract (half the coefficient of the x- term)² to x² - 18x
4(x² + 2(- 9)x + 81 - 81) = 0
4(x - 9)² - 4(81) = 0
4(x - 9)² - 324 = 0 ( add 324 to both sides )
4(x - 9)² = 324 ( divide both sides by 4 )
(x - 9)² = 81 ( take the square root of both sides )
x - 9 = ±
= ± 9 ( add 9 to both sides )
x = 9 ± 9
Then
x = 9 - 9 = 0
x = 9 + 9 = 18
