Answer:
$104
Step-by-step explanation:
10% = 160 ÷ 10 = $16
5% = $16 ÷ 2 = $8
30 % = 16 x 3 = $48
48 + 8 = $56
$160 - $56 = $104
Hope this helps!

1) 2x + 8y = 20
y=2
Answer:
2x+8y=20;y=2
Solution :
{x,y} = {2,2}
System of Linear Equations entered :
[1] 2x + 8y = 20
[2] y = 2
Graphic Representation of the Equations :
8y + 2x = 20 y = 2
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = 2
// Plug this in for variable y in equation [1]
[1] 2x + 8•(2) = 20
[1] 2x = 4
// Solve equation [1] for the variable x
[1] 2x = 4
[1] x = 2
// By now we know this much :
x = 2
y = 2
We are done
Solution :
{x,y} = {2,2}

Answer:
Lori spends 9 minutes on sketching th of a sketch.
Step-by-step explanation:
Given equation:
where number of minutes Lori spends on sketching
and number of sketches Lori makes.
We need to calculate the time spent by Lori in sketching of a sketch.
So we know the value of as represents number of sketches and in this situation Lori has sketched only a fraction of a painting.
So we plugin in the equation and calculate which is time spent by Lori sketching th of a sketch.
∴ minutes (Answer)
∴ Lori spends 9 minutes on sketching th of a sketch.
The solution to the given quadratic equation buy factoring is: x = -7 or 7
A quadratic equation is an equation of degree 2 and has the standard form: ax² + bx + c = 0, with a ≠ 0
We can solve quadratic equations by:
- Completing the square
- Quadratic formula
- Factoring
We are given the quadratic equation as:
x² - 49 = 0
Factoring this gives us:
(x + 7)(x - 7) = 0
Thus:
x - 7 = 0 or x + 7 = 0
x = -7 or 7
