Answer:
x=-5/3
Step-by-step explanation:
Add 5 to both sides to get 5=-3x.
Then divide by -3.
And get -5/3=x
(x + 4)(x - 4)
x2 - 4x + 4x - 16
x2 - 16
The statement above is False.
Answer:
914 and 916
Step-by-step explanation:
let the first integer be x
The next largest consecutive even integer is hence x+2
given that the 2 integers add up to 1830,
x + (x+2) = 1830
2x + 2 = 1830
2x = 1828
x = 914
Hence the first number is 914
the second number is 914 + 2 = 916
Check Answer:
914 + 916 = 1830 (verified)
7.125 is the anwcer to that
<span>The answer is 9.52 kg.
The density (D) of is quotient of mass (m) and volume (V):
</span><span>D = m/V
It is given:
m = ?
D = 0.680 g/cm³
V = 14 L = 14 d</span>m³ (1 L = 1 dm³) = 14000 cm³<span>
</span>Since <span>D = m/V, then m = D*V
</span>m = 0.680 * <span>14000
= 9520 g
= 9.52 kg</span>
