Which expression is equivalent to -2(39 - 2) - (48 + 3)? 1.-10g+7
2.-10g + 1
3.7g-1
4.-1g + 7

2 (assuming equatin you meant was -2(3g - 2) - (4g + 3))

Step-by-step explanation:

-2(39 - 2) - (48 + 3)

-78+4-48-3

= - 125

(assuming that your equation instead is -2(3g - 2) - (4g + 3)

-6g+4-4g-3

-10g+1

0.02

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
