Ned took a test with 25 questions. He lost 4 points for each of the 6 questions he got wrong and earned an additional 10 points for answering a bonus question correctly. How many points did Ned receive or lose overall?

He lost 24, and recieved 10.

Step-by-step explanation:

If i did this correctly, each question is worth one point. In this case, since he lost four points for each of the 6 incorrect answers, you would do 4 x 6  = 24, so he lost 24 points. Then, he got ten more for answering this bonus question, he got ten more, so that would leave him with 11 points because, as i said, i believe each question is one point. so the whole equation is

25-(6x4)+10=11

Hope this helps! :)

its not b

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!
