|-4 + 5x| = 16 when x = -12/5 I know the answer to x(-12/5) but I don’t know how to show my work.

x = 12/5

Step-by-step explanation:

Absolute value--> 4 + 5x

First subtract 4 from both sides

5x = 12.

Divide 5 from both sides. Then you'll have x = 12/5.

Idk where you got the negative from.

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!
