C makes no sense because it is not equal to 372
AB make no sense since it is supposed to be 2x not 2y
D is the only reasonable answer.
Answer:
Okay So I see you need to change 1/3 to a denominator of 6
You don't do anything to the -1/6
But to change the 1/3 you need to multiply 3 and 1 by two, which is 2/6
And the -1/6 stays the same
Answer:
The answer is 4.
Step-by-step explanation:
The value of a in ax^2 - 40x + 109 = 0 when one solution to the quad equation is x = 5 + 3 over 2i is 4.
Answer:
x = - 104, y = - 130
Step-by-step explanation:
the quotient of the 2 numbers is
= 
( cross- multiply )
5(x + 26) = 4x
5x + 130 = 4x ( subtract 4x from both sides )
x + 130 = 0 ( subtract 130 from both sides )
x = - 130
First number is - 130 + 26 = - 104
second number is - 130
solution:
its simple volume of 1 sand grain = (0.10 mm)³ = 0.001 mm³
1 mole sand x (6.02214x10^23 grains / mole) x (0.001 mm³ / grain) = 6.02214x10^20 mm³
268,601 mi² x (5280 ft / mi)² x (12 in / ft)² x (2.54 cm / in)² x (10 mm / 1 cm)² = 6.95673x10^17 mm²
V = height x area
height = V / A = 6.02214x10^20 mm³ / 6.95673x10^17 mm² = 865.657 mm
finally...
865.657 mm x (1 cm / 10 mm) x (1 in / 2.54 cm) x (1 ft / 12 in) = 2.84008 ft... 6 sig figs.
