10 red marbles
Multiply the # of blue marbles by 2 (since there was TWICE as many red marbles), and you have your answer (above)
For this case, the first thing we must do is define variables.
We have then:
x: number of times Giselle uses the athletic club
b: amount of money remaining
We write a linear equation of the form:
b = mx + c
Where,
m: slope of the line that represents the cost for each time she uses the athletic club
c: initial amount that Giselle paid
Substituting values we have:
b = -10x + 190
Answer:
a linear function that model the situation is:
d. b = 190 - 10x
There are 6 sides to a hexagon and each side of the fence will be 6+2 = 8 feet
So you'll need 8*6 = 48 feet of fencing.
Answer:
3n = 3 - 3n
<=>
6n = 3
<=>
n = 2
=> This equation has one solution.
