What is -7+p=3 give me a step by step explanation.

p=10

Step-by-step explanation:

1.add 7 on each side to cancel -7

2.add 7 and 3 together to get ten

p=10

Step-by-step explanation: simplify both sides of the equation p-7=3

Add 7 on both side -7+7 and 3+7 then u will divine p from 10 which will be 10 because you will get 10/1

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!
