Write the number equal to 7 tens and 3 ones

73

Step-by-step explanation:

There are 7 tens, so we can add "10" seven times:

This is equal to 70.

There are 3 ones, so we can add "1" three times:

This is equal to 3.

So

73 is the correct 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

i think it might be a but you might want a second opinion
