because the cross products are equal, which statements are true? select all that apply.

the ratios are not equivalent.

the ratios are equivalent.

the ratios are not a proportion.

the ratios are a proportion.

The ratios are equivalent and the ratios are proportional.

Step-by-step explanation:

Shelley sold one customer 5 peanut butter biscuits for $3 and she sold another customer 7 beef treats for $4.20.

Therefore, the cost of 1 peanut butter biscuit is Dollars.

Again the cost of 1 beef treat is Dollars.

So, the cost of 1 peanut butter biscuit is equal to the cost of 1 beef treat.

Therefore, the ratios are equivalent and the ratios are proportional. (Answer)

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
