If a = 2b^3 and b = − 1/ z c^−2, express a in terms of c.

m_a_m_a [10]

Answer:

a = -2 z^-3 c^6

Step-by-step explanation:

equations are given as

a = 2b^3 .....1 and

b = -1/ z c^-2 .....2

put the value of b in eq 1

a = 2(-1/z c^-2)^3

a = 2(-1/z^3 c^-6)

or a = -2 z^-3 c^6

5x+6+92 = 22x-4

5x+98 = 22x-4

add 5x to both sides

98 = 27x-4

add 4 to both sides

102 = 27x

divide both sides by 27

x = 3 and $\frac{7}{9}$
