Answer:
A
Step-by-step explanation:
To find this quotient, we divide each term inside the parenthesis by
. Then we simplify. So we have:

Answer choice A is correct.
Answer:
Step-by-step explanation:
2a+3b+2k= $3.19
3a+4b+2k=$4.12
1a+1b+4k=$3.01
A plane parallel to vectors <9, 6, 2> and <-8, -4, -5> is given by

Since the plane passes through point (5, -5, 8), then
-22(5) + 29(-5) + 12(8) = -110 - 145 + 96 = -159
The required plane is -22x + 29y + 12z = -159
z = 11/6x - 29/12y - 53/4
Answer:
True: 5, 15, and 10
Step-by-step explanation:
6*5=30 Correct, 30 is less than 100
6*15=90 Correct, 90 is less than 100
6*10=60 Correct, 60 is less than 100
6*20=120 Wrong, 120 is greater than 100
Using the information from the question, one can construct two equations:

... (1)

... (2)
by substituting (1) into (2) to find x


\frac{5}{4z} = \frac{1}{4}



⇒ z = 5
By substituting value of z into (1)
⇒ 4 (5) = x
⇒ x = 20
Thus the two numbers are 5 & 20
