Answer:
You will have 128 orange marbles
Step-by-step explanation:
Set this up as an equation
Variable x = number of orange marbles
3/8 = 48/x
Cross multiply
3 × x = 8 × 48
3x = 384
Divide both sides by 3 to isolate the variable
3x ÷ 3 = 384 ÷ 3
1x = 128
x = 128
128 orange marbles
Check work:
Substitute the variable x for the answer
3/8 = 48/128
Cross multiply
3 × 128 = 8 × 48
384 = 384
If the numbers equal, the answer is correct
Answer:
The correct answer is 10 units.
Step-by-step explanation:
Profit function of a small business is given by P(x) = 0.3
+ 7x - 40, where x is the number of units sold.
The small business intend to make a profit of $60.
To find out the number of units the business has to sell in order to have a profit of $60 is given by,
P(x) = 0.3
+ 7x - 40 = 60
⇒ 0.3
+ 7x - 100 = 0
⇒ 3
+ 70x - 1000 = 0
⇒ x = -70 ±
× ![\frac{1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7D)
⇒ x = -70 ± 130 × ![\frac{1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7D)
⇒ x = 10 or -![\frac{200}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B200%7D%7B6%7D)
Quantity sold cannot be negative giving us the value of x as 10 units.
Since there are 18 dogs.
And fraction denominator is 1/3
It will be divided by 6
And since ges walking 1/3 of the dogs he is originally walks with which is 18
That means the answer is 6.
