Plz answer this the one i circled

We can setup an equation for this.

Boys to Girls = 2:7

Boys =  x

Girls = 250+x

Setup the ratio

x:(250+x) = 2:7

x / (250+x) = 2/7

7x = 500+2x

7x-2x = 500

x = 500/5 =100

There are 100 boys at the concert

Hope this helps:)

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

they go with it happens or they mite give a chance?
