First, you would need to create an equation for this problem. Let x represent the number of sales made.
$100 + $3x = $160
Next, you would need to isolate the x.
Subtract $100 from both sides.
$3x = $60
Now, all you would need to do is divide both sides by $3.
x = 20
You would need to make at least 20 sales.
I hope this helps!
Answer:
Without seeing the expressions that you can choose from, I can't tell you which one is correct, but I can tell you that n + n - 0.24n is equal to 1.76n
Answer:
The answer is 4y.
Step-by-step explanation:
First you would solve the parentheses, which would be -1(-3y) which would equal positive 3y, and y+3y=4y. I apologize if I misunderstood the problem ^^
Answer:
96 yards
Step-by-step explanation:
This is basically just a huge addition problem that we can tackle (heh) in our heads.
If we gain yards, then we add.
If we lose yards, then we subtract.
If we started out at 50, the expression is
.
We can use the associative property of addition to simplify this. I'm just grouping together things that look easy to do in my head.

Hope this helped!
Answer:
the answer is
A. X=2, y=6
Step-by-step explanation:
use substitution
y= 6 so,
y-3 = 6-3 which is 3
and y-1 = 6-1 which is 5
now for x
x=2
x+3= 2+3 which is 5
2x-1= 2(2)-1
2 times 2 is 4
4-1 = 3
