Answer:
<u>Jack has at least 15 marbles: 12 red, 2 blue and 1 yellow.</u>
Step-by-step explanation:
1. Let's review the information given to us to solve the problem correctly:
Number of red marbles = 10 more than blue marbles
Number of yellow marbles fewer than blue marbles
2. How many of each color marble could Jack have?
r = Number of red marbles
b = Number of blue marbles
y = Number of yellow marbles
r = b + 10
y < b
If y = 1, then b ≥ 2, and r = b + 10,
fulfilling the three conditions, we have:
<u>y = 1, b = 2, and r = 12</u>

Answer:
C
Step-by-step explanation:
Anything less than 5 rounds down while 5 and anything more rounds up. Therefore...
15.3 rounds to 15
7.9 rounds to 8
7.4 rounds to 7
So, his answer is reasonable.
Answer:
I don’t see any graphs. Try copying android pasting images.
Step-by-step explanation:
So, x = 13, x = √3 and x =7i.
now, recall that for an EVEN radical, there are two possible roots, namely is say √3 is say hmmm some value "a", that means that a*a = √3, however, -a*-a is also √3, therefore, ±√3 are two valid values, and therefore -√3 is another one.
now.... keep in mind that, complex solutions or roots, never come all by their lonesome, their sister is always with them, the conjugate, so, for 7i or namely 0 + 7i, her sister is always around, 0 - 7i, which is the other root.
