Hakeem subtracted 8 from a number, then multiplied the difference by
4/5. The result was 20. Write and solve an equation to find the
number, x.

  33

Step-by-step explanation:

8 subtracted from the number is ...

  x -8

and 4/5 of that value is ...

  4/5(x -8)

The equation will say this result is 20:

  4/5(x -8) = 20

__

Multiplying by 5/4, we get ...

  x -8 = 25

  x = 33 . . . . . . add 8

The number, x, is 33.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
