80% of 4000 is 3200, so 800 disagreed, and 3200 agreed.
6 days
Y= 107-8x
Y=83-4x
You can use substitution
83-4X= 107-8x
Bring 8X
Over to the left
83+ 4x=107
Subtract 83
4x= 24
X=6
Or put in calculator and go 2nd graph you see table and on 6 day they both have $59
<h3><u>
The value of x is greater than the value of 3.</u></h3>
We can treat inequalities like standard algebraic equations.
7x - 9 > 2x + 6
<em><u>Add 9 to both sides.</u></em>
7x > 2x + 15
<em><u>Subtract 2x from both sides.</u></em>
5x > 15
<em><u>Divide both sides by 5.</u></em>
x > 3
Answer: 3.75 g
Step-by-step explanation:
Assume the weight of the square is x.
The hanger is in balance so the left side is equal to the right side.
Equation therefore is:
Triangle + Square + 3 * circle = 5* square + circle
3 + x + (3 * 6) = 5x + 6
3 + x + 18 = 5x + 6
5x - x = 3 + 18 - 6
4x = 15
x = 15/4
x = 3.75 g
