Given m||n, find the value of x.

x = 16

Step-by-step explanation:

the two angles are vertical angles.

vertical angles are equal.

4x - 7 = 3x + 9

subtract 3x from both sides of the

4x - 3x - 7 = 3x + 9 - 3x

x - 7 = 9

add 7 to both sides of the equation

x - 7 + 7 = 9 + 7

x = 9 + 7

x = 16

your answer would be 10x - 1

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
