Change=given-cost
cost=total cost=cost for all of them added together
cost=popcorn+small drink+fruit snacks
cost=4+3+5
cost=12
given=x
change=3
3=x-12
that is the equation
solve
add 12 to both sides
15=x
he gave $15 to the cashier
What statement? I don't get it
The common factors for 28 and 42 are 1, 2, 7 and 14.
Answer:
Below in bold.
Step-by-step explanation:
Standard form is Ax + By = C
where A, B and C are integers and A must be positive.
So the first 2 are already in standard form but the last 2 can be converted to standard form by multiplying each term by -1:
-12x+3y=27
= -1*-12x + -1*3y = -1*27
12x - 3y = -27 is the answer.
The last one is:
24x + 12y = -60.
A 2/5 or 2:3
b 25% or 1/4
im 90% sure this is correct
