Hey You!
1.
31.29/6 = 5.215
5.215 × 2 = 10.43
2 brushes cost $10.43
2.
31.29 × 3 = 93.87
93.87 * 10% = 9.387
93.87 - 9.387 = 84.483
3 cases would cost $84.48
Answer:
1.67 people per minute
Step-by-step explanation:
it's a proportion, basically. 5/3 = x/1, solve and you get 1.67. BTW if only five people enter in the span of 3 minutes, then this store needs to invest in advertising more, because i've seen CVS's with a better ratio than that. and that's sad!
Explanation:
The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.
Due to a lack of context, I’m guessing you want the equation of this line. If you go back to the equation y = mx + b, m represents SLOPE, and b represents the y-int (0, b).
As the slope is -2 and the y intercept is (0,0), the line’s equation would be y = -2x + 0, or simply y = -2x.
Answer:
The probability is 2/11 or 7/95. I don't know if this is the correct answer but I am guessing it is.
