Answer:
-56-7k
Step-by-step explanation:
=> -7(8+k)
Expanding brackets using distributive property
=> (-7*8) + (-7*k)
=> -56 + (-7k)
=> -56-7k
Answer:
r = -8/5
Step-by-step explanation:
-7 log4 (-10r) = -14
Divide each side by -7
-7/-7 log4 (-10r) = -14/-7
log4 (-10r) = 2
Raise each side to the base of 4
4^ log4 (-10r) = 4^2
-10r = 16
Divide each side by -10
-10r/-10 = 16/-10
r = -116/10
r = -8/5
Get a common denominator first.
89/120 becomes 1157/1560
90/130 becomes 1080/1560
Subtract the two and you get 77/1560
