Answer:
1.
x=# of purple marbles
y=# of yellow marbles
y=3x
y+x=164
3x+x=164
4x=164
x=41
There are 41 purple marbles and 41*3=123 yellow marbles.
2.
L=large fries
H=hamburger
H=1.15+L
2H+L= 8.60
2.3+2L+L=8.60
2.3+3L=8.60
3L=6.3
L=2.1
A large fries costs $2,1 while a Hamburger costs 1.15+2.1=$3.25.

once you divide you get the answer hope this helps. I also feel like an idiot sometimes trust me. I ate a hamster treat once so if you ever feel bad remember there is someone out there who ate a hamster treat and drinks paint water.
Answer:
y = 34
Step-by-step explanation:
PEMDAS =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
Remember to follow PEMDAS. First, multiply -6 with 4:
-6 * 4 = -24
-24 + y = 10
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. Add 24 to both sides:
-24 (+24) + y = 10 (+24)
y = 10 + 24
y = 34
y = 34 is your answer.
