The length of the base of an isosceles triangle is x. The length of a leg is 3x - 7. The perimeter of the triangle is 91. Find X.

Step-by-step explanation:

the perimeter =

x + 2(3x-7) = 91

x + 6x -14 = 91

7x -14 = 91

7x = 91+14

7x = 105

x = 105/7

x = 15

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
