Answer:
1/6
Step-by-step explanation:
Make the denominators the same by finding the lcm(least common denominator). The least common demominator would be 24. So multiply both numbers in 1/8 by 3. This would eaqual 3/24. Multiply both numbersin 4/3 by 8. This would equal 
= 
. Simplify 96/576 by dividing both numbers by 96.
<u>96</u> ÷ 96 = <u> 1 </u> 576 ÷ 96 = 6 and that becomes 1/6.
Answer:
The expression for two times the difference of 4 and a number is
Step-by-step explanation:
To Find:
Write an expression for Eight times the difference of 4 and a number.
Solution:
Let the Unknown number be 'd'
Difference of 4 and d = ( 4 - d )
So One Time Difference of 4 and d = 1× ( 4 - d )
∴ Two Times Difference of 4 and d = 2× ( 4 - d )
∴ Eight Times Difference of 4 and d = 8× ( 4 - d )
The expression for Eight times the difference of 4 and d. will be
The expression for Eight times the difference of 4 and a number is
Answer: 1.2x
Step-by-step explanation:
Profit = Selling price - Cost
She bought the stock at a cost of x dollars
Her profit was 20% of that, which is 0.2x dollars
Selling price = Profit + Cost = x + 0.2x = 1.2x
Responder:
Copias del libro A = 50
Copias del libro B = 70
Explicación paso a paso:
Costo por libros A = 200
Costo por libro B = 150
Sea el número de libros A = x
Número de libros B = y
Número total de libros comprados = 120
Costo total = 20,500
x + y = 120 - - - (1)
200x + 150y = 20500 - - - (2)
De 1)
x = 120 - y
Sustituya x = 120-y en (2)
200 (120 - años) + 150y = 20500
24000 - 200y + 150y = 20500
24000 - 50y = 20500
-50 años = 20500 - 24000
-50y = - 3500
y = 70
x = 120 - y
x = 120 - 70
x = 50
Answer: 320 triangles
Step-by-step explanation: Triangles can be drawn utilizing one side of the polygon. In the event that we take one side, at that point there are a add up to of 16 triangles that can be drawn and we have 20 sides. So, add up to 20×16=320 triangles.
