The answer is 3!
explanation; 3x10 equals 30. the difference is 27 years and 30-3=27!
It would be: 21 * (6.3 * 10⁻⁴)
= 132.3 * 10⁻⁴
= 1.323 * 10⁻²
In short, Your Answer would be: 1.323 * 10⁻²
Hope this helps!
Answer:
−22.599a−32.513
Step-by-step explanation:
Distribute:
= (4.1) (−7.93) + (4.1) (− 4.39 a) + − 4.6 a
= − 32.513 + − 17.999 a + − 4.6 a
Combine Like Terms:
= −32.513 + − 17.999 a + − 4.6 a
= (− 17.999 a + −4.6 a) + (− 32.513)
= − 22.599 a + (− 32.513) = − 22.599 a − 32.513
Answer:
25.5 and 37.5
Step-by-step explanation:
x+y=63
x-y = 12 then x = 12 + y sub this into the first equation
(12+y) + y = 63
12 + 2y = 63
2y = 51
y = 25.5 then x = 37.5
