3. 100 x 4.5 answer these 2
4. 0.008 x 102
estimate each product.
5. 0.38 x 99
6. 8 x 56.7
7. 11 x 4.89
8. 24 x 3.9

step-by-step explanation:

subtract 7, so the answer is x < = 3, or c.

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
