What is the simplified form of the expression k^3(k7/5)^-5

saveliy_v [14]

The expression can be simplified as:

k^3(k7/5)^-5
= k^(3+-5) * (7/5)^-5
(Collecting the powers of k at one side and the constants at other side)
= k^-2 * (5/7)^5
(Solving thr integer powers)
= k^-2 * (3125/16807)

15(t+2)+9t=6 Please help!

yawa3891 [41]

Answer:

t = -1

Step-by-step explanation:

15(t+2)+9t=6

15t + 30 + 9t = 6

combine like terms

24t +30 = 6

subtract 30 both sides

24t = -24

t = -1

22-5(6v-1) = -63

22- 30v + 5 = -63

27 -30v = -63

subtract both sides by 27

-30v = -90

divide it by -30

v = 3
