First, use distributive property on the right half.
2 * 5 = 10
2 * 2n = 4n
4n - 9 = 10 + 4n
Add 9 to both sides
4n = 19 + 4n
Subtract 4n from both sides
0 = 19
But thats not true. Therefore, there is no solution.
1+3+6=10
40=10 units
diidde by 10
4=1unit
4 times 1=4
4 times 3=12
4 times 6=24
they paid $4, $12 and $24
Hoi! Its your friend Nat here to help!
All we need to do is
2.70+3.60
Which is 6.3
Hope dis helps!

Take a look at <span>y = mx^2 – 5x – 2. This is a quadratic equation with a=m, b= -5 and c= -2. What is the discriminant, b^2 - 4ac? (-5)^2 - 4(m)(-2).
There will be 2 complex roots if this discrim. is < 0. Thus, solve
25 + 8m < 0:
Subtr. 25 from both sides: 8m < -25
Div. both sides by 8: m < -25/8
Conclusion: If m is less than -25/8, there will be no real roots (and thus, no x-intercepts). </span>
