Answer:
1) B. n ≥ 3
2)A. 5x – 9
Step-by-step explanation:
1)
If the least value of n is 3 then all the values of n must be greater or equal to 3
Thus the correct option is B :n ≥ 3
2)
Given:
Milo's age is 9 years less than 5 times Pearl's age
Pearl's age is x years
5 times Pearl's age= 5x
then milo's age= 5x-9
so the correct option is A. 5x – 9 !
Let's define what as 'x'
3x = 75
Divide both sides by 3.
3x/3 = 75/3
x = 75/3
x = 25
Three times twenty five equals 75.
Your final answer is twenty five or 25.
Answer:
7 / 15
Step-by-step explanation:
Fraction before painting = 5/6
Fraction left after painting = 11/30
Fracrion used = difference of the fraction before painting and fraction left after painting
Fraction used = 5/6 - 11/30
Lowest common factor of 6 and 30 = 30
5/6 - 11/30 = (25 - 11) / 30 = 14/ 30
Fraction used = 14/30 = 7/15
Answer:
x = 8 ; x = -3
Step-by-step explanation:
Sum = -5
Product = - 24
Factors = 3 , (-8)
x² - 5x - 24 = 0
x² - 8x + 3x - 3 * 8 = 0
x(x - 8) + 3(x - 8)= 0
(x - 8)(x + 3) = 0
x - 8 = 0 ; x + 3 = 0
x = 8 ; x = -3
