(5x - 2) + (5x - 2) + (x + 3) +  (x + 3) = 50 \\ 12x + 2 = 50 \\ 12x = 50 - 2 \\ 12x = 48  \\ x = 4

k-4/3= 3

Mutiply both sides by 3 .

(3)(k-4/3)= (3)(3)

Cross out 3 and 3 , divide by 3 and then becomes k-4= 9

Move -4 to the other side

Sign changes from -4 to +4

k-4+4= 9+4

k= 13

Answer: k= 13

Someone help with this please!!!!
damaskus [11]

Answer:

10^{4} * 10^{3}=(10*10*10*10)(10*10*10) = 10^{7}\\\\10^{4}*10^{4}=(10*10*10*10)(10*10*10*10) = 10^8\\\\(10*10*10)(10*10*10*10*10)=10^3*10^5=10^8\\

10^{18}*10^{23}= (10 x 10 18 times)(10 x 10 23 times) =10^{41}

just as a note: when you multiply numbers with exponents and they both have the same base, all you have to do is add the exponents.

Ex: 10^{5}*10^{4}=10^{5+4}=10^{9}
