7. Mr. Swan's homeroom class has 7 boys and 6 girls. He randomly chose 2 students for a project. What is the probability that at least one of the students he chose was a
girl?

(01.02 MC)Which of the following uses absolute value correctly to show the distance between −30 and 16? a. |−30 − 16| = |−46| = −46 units b. |−30 − 16| = |−46| = 46 units c. |−30 + 16| = |−14| = 14 units d. |−30 + 16| = |−14| = −14 units

Hope that helps!

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
