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

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

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
