Need help, not sure if I got the correct answer.

The length of the ladder is 15 feet.

Solution:

Let the length of the ladder be x.

Distance from ground to the top of the ladder = x – 3

Distance from the bottom of the ladder to the building = 9 feet

To find the length of the ladder:

Using Pythagoras theorem,

Subtract from both sides of the equation, we get

Subtract 90 from both sides of the equation.

–6x = –90

Divide by –6 on both sides of the equation.

x = 15

Hence the length of the ladder is 15 feet.

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

okay..i will pick 8!
