Answer: 685 red marbles
Step-by-step explanation:
Lets set up a proportion:
x/1096 = 5/8
(For every 8 marbles, 5 of them are red)
Then we cross multiply
5480 = 8x
and divide!
so 685 marbles
When we add two equations, it's important to <em>combine like terms</em>
<u>x's with x's </u>
<u>y's with y's </u>
<u>and constants with constants</u>
2x + 5x = 7x
3y + (-y) = 2y
-5 + -12 = -17
Let's put <em>everything together </em>for a final equation
7x + 2y - 17 = 0
or
7x + 2y = 17
Answer:
The answer is 120
Step-by-step explanation:
