If Y +Y + 40 = 180 in an isosceles triangle so Y =?

a) 140
b) 70
c) 110
d) 0

If Y +Y + 40 = 180 in an isosceles triangle so Y =?

b) 70

Step-by-step explanation:

Y + Y + 40 = 180

2y + 40 = 180

2y = 180 - 40

2y = 140

y = 140/2

y = 70

So, the value of Y is 70 (b)

#CMIIW ^^

y = 40

Step-by-step explanation:

because y = 40 +y =40 +40 =180

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

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
