Hello!
ANSWER:
The selling price would be $380.80.
Convert the percentage to a decimal by dividing it by 100.
36% ÷ 100 = 0.36
Find 36% of the cost of the TV:
280 × 0.36 = 100.8
Add:
280 + 100.8 = 380.8
X + y + z = 27
x = 2z
y = 3 + z
2z + 3 + z + z = 27 ; 4z = 24; z = 6 youngest
x = 12 oldest
y = 9 middle one
Answer:
4
Step-by-step explanation:
1 + 1 + 1 + 1 = 4
2 + 1 + 1 = 4
3 + 1 = 4
4 = 4

Answer:
Step-by-step explanation:
<u>Let the number be x:</u>
- 2x = 5x + 12
- 2x - 5x = 12
- -3x = 12
- x = -4
It is -4
16+5x =8x-5
Reorder the terms
16+5x = -5+8x
Solving for variable for x
Move all terms containing x to the left, all other terms to the right.
Add -8x to each side of the equation.
16+ -3x = -5 + 8x + -8x
Combine like terms: 5x + -8x=-3x
16+-3x = -5 + 8x + -8x
Combine like terms: 8x + -8x = 0
16+-3x = -5 + 0
16+ -3x = -5
Add -16 to each side of the equation
16+-16 + -3x = -5 + 16
Combine like terms: 16+ -16 = 0
0 + -3x =-5 + -16
-3x = -5 + -16
combine like terms: -5 + -16 = -21
-3x = -21
Divide each side by -3
x=7
