find x

x= 8

Step-by-step explanation:

All interior angles of a triangle equal 180 degrees.

Write it out as an equation:

180= 8x-4 + 6x+2 + 9x-2

Simplify:

180= 23x-4

Add four to both sides.

184= 23x

Then divide both sides by 23 and get 8 = x

25/4

step-by-step explanation:

call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.

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
