Answer:
B (8)
Step-by-step explanation:
AB = BC = AC
AB = BC
x+5 = 3x-1
6 = 2x
x = 3
BC = 3x-1 = 3*3 - 1 = 8
Answer:
<h2>$5.75</h2>
Step-by-step explanation:
Step one:
given data
initial balance= $10
she earned extra $23.50 doing errands
hence her balance will be
=10+23.5

Answer:
Step-by-step explanation:
A geometric mean is just ![\sqrt[n]{term one * term two * term three * etc.}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bterm%20one%20%2A%20term%20two%20%2A%20term%20three%20%2A%20etc.%7D)
, where n is the number of terms.
i.e. Geometric mean of 5, 6, 7: there are three values, so the mean is ![\sqrt[3]{5*6*7}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5%2A6%2A7%7D)
Answer: y = 2/1x + 2
Step-by-step explanation:
A slope of 2 means rising 2 and run 1 on a graph. This would make x = 2/1. The + 2 allows the line to pass through (0,2) and therefore it will also pass through (-2,-2).
Well, it depends on what the weight of the test is. Most courses tell you that a test is worth a certain percentage of your grade(i.e. Final Exam is worth 20% of your entire grade). It also depends on what your grades for other assignments were, and how many there were. Try asking your teacher.
The average of your previous grade and the grade you got on your test is 84.5%. Average is the mean, which is calculated by: (91 + 78)/2.
