5(2x-8)+15=-15
10x-40+15=-15
10x-25=-15
10x=10
x=1
The next day, you charge $3.50 for each bracelet. You have a supply of 30 bracelets, and exactly 30 customers demand them. At the end of the day, there is no excess demand or excess supply. So, $3.50 must be the <u>equilibrium price</u>
the correct answer is the bolded, underlined words. I hope this helps, have a great day, chao!!
Answer:
Step-by-step explanation:
We have two fractions and are being asked to subtract them.
7/8 and 1/3 don't have the same denominator, so to do as so, we need to find the LCM of both denominators, multiply them to that, and do the same for the numerators.
So what is the LCM (Least Common Multiple) of 8 and 3?
24.
Therefore :
Answer:
No, because water temperature is confounded with brand of detergent.
Step-by-step explanation:
There is a very possible chance of allowing a third or confounding variable to have creepwd into the research. The aim was to investigate which of two detergents prevents color from fading. Hence, the test for both detergents should be carried out under the same research condition. However, with adoption of different water temperature for each of detergent A and B, there may be a relationship between fading and water temperature which is not what are trying to investigate. This difference in temperature will thus cause a spurious relationship in our research. Hence, water temperature has been confounded with detergent brand, making this experimental design a bad one.
B. Compare independent variables
