Answer:
the first 2
Step-by-step explanation:
5(6x + 3) + 4x = (6x + 3)5 + 4x due to the commutative rule of the multiplication (a×b = b×a).
and when you simplify the expression we get
5(6x + 3) + 4x = 30x + 15 + 4x = 34x + 15
so, the first two answer options are correct
Answer:
81/64
Step-by-step explanation:
(-8)^-2
----------------
3^-4
Negative exponents move the item from the numerator to the denominator, and from the denominator to the numerator
(3)^4
----------------
(-8)^2
Now evaluate the power
81
---------
64
62% because 200 silver coins out of 323 (total of all coins) is .619..., resulting in 62%
Answer:
- 3
Step-by-step explanation:
6 - 4x = 6x - 8x + 12
6 - 4x = - 2x + 12
6 - 12 = - 2x + 4x
- 6 = 2x
x = - 6 / 2
x = - 3
An expression for the difference between the two reaction times would be
√0.18 - √0.08. The result will be positive.
