Step-by-step explanation:
To find unit rate
1 bag = 36÷ 3 = 12
So unit rate = $12
Answer:

Step-by-step explanation:
using the rule of exponents
•
= 
= 
Standard form is just putting (in this case) variables in alphabetical order. First we simplify- 2x+4=4y would become 1/2x+1=y. This is already in standard form, as numbers w/o variables come at the end. simplifying the next one is more tricky. first you get a variable/number alone-
9-2x-2y=4x+3
9-2y=6x+3
6-2y=6x
1-1/3y=x
1=x+1/3y
3=x+y
x+y=3
sorry if I was wrong and not of any help, But I do believe this is correct.
Answer: B & D
Step-by-step explanation:
In this scenario we want to come out with a situation where both sides are in an even playing field, as the equation solves to zero.
If a diver is 35 feet below water (-35) and he comes up to breathe, he goes up 35ft (35) meaning he is at the surface (0).
If Manuel is in debt for 35$ (-35) and then he pays off the 35$ (+35) then he is even (at 0).
Part A:
- np -80 <60
Adding 80 both sides
- np < 140
Dividing by -p both sides
n > -140/p
Part B:
2a - 5d =30
5d = 2a-30
d= (2a-30)/5
