Solve for x. 16 = -2x - 1 x = -8 x = -7 x = 7 x = 8

x = - 8.

Step-by-step explanation:

Given  : 16 = -2x - 1

To find : Solve for x.

Solution : We have given

16 = -2x - 1

On adding both sides by 1

16 + 1 = -2x .

17 = - 2x

On dividing both sides by -2.

x = - 8. 5

If we rounded it it would be - 8 .

Therefore, x = - 8.

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
