It’s 27 for sure because (7-5) is 2 times that by the power of 2 is 4 times that by 6 is 24 and 3 +24 is 27

Last week, mallory flew two round trips. They were 3,720 miles and 5,985 miles. Select all of the choices that are good estimate

Answer:

Mallory flew in total 10,000 miles, rounded :D

Step-by-step explanation:

Since we're using rounding to place values, first we have to have the total amount of miles flown by Mallory, so we make the sum:

3,720 + 5,985 = 9,705 miles

then, we have to round thefirst digit to the right following this rule

0-4 is rounded down

5-9 is rounded up

now, since the number we want to round is the first digit on the left (9), and following the rules above, we change the "9" for a "10". the rest of the numbers are now transformed into zeros (0)

9,705 >>> rounding it up >>> 10,000

Let me know if you have any questions XD

Katya tutors and works in the college bookstore to pay for her college tuition. She makes $20 per hour tutoring and $8.50 per ho

strojnjashka [21]

We have to write the equation which represents Katya's earnings while tutoring and working in a book store is given as follows:

She makes $20 an hour while tutoring. Let's say she tutors for 'x' hours in a day. So, she will make $20 \times x = 20x$ dollars by tutoring in a day.

She makes $8.50 an hour while working in the bookstore. Let's say she works for 'y' hours in the bookstore in a day. She will make $8.50 \times y = 8.50y$ dollars by working in the bookstore.
