Diamond used a number line to add. She started counting at 10, and then she counted until she was on the number −4 on the number line. Diamond is modeling addition. You may use the number line to help you arrive at your answer. * 10 + (-4) = 6 10 + (-14) = -4 10 - 4 = 6 10 + (-6) = 4

10 + (-14) = -4

Step-by-step explanation:

Given that,

Diamond used a number line to add. She started counting at 10, and then she counted until she was on the number −4 on the number line.

For addition, she will add 10 and (-14) as follows :

10 + (-14) = -4

So, the crrect option is (b) "10 + (-14) = -4".

answer is 144

step-by-step explanation:

3

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!
