0.5x+0.25y= 3 equivalent slope-intercept form equation

y=-2x+12

Step-by-step explanation:

Get the x over to the other side by subtracting it

0.25y=-0.5x+3

Multiply all by 4 to get 0.25y to 1y

y=-2x+12

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!

hope this is what you were asking for!
