Answer:
y = 8
x = 9
Step-by-step explanation:
given equation,
x + y = 17 ........(1)
9 x - y = 73...........(2)
writing in matrix form
A X = B
using augamented matrix A|B
using row transformation
R₂ = R₂ - 9 R₁
now,
now
-10 y = -80
y = 8
and
x + y = 17
x = 17 -8
x =9

Step-by-step explanation:
<u>Modeling of Reality</u>
Sometimes we have a real situation and we want to provide a mathematical model to explain it. But what if we have the model and need to imagine what the situation could be? It calls for our imagination and tries to figure out such a problem, given the answer
We can see a question mark multiplying the fraction 1/8 to produce a result of 3. This is a common proportion problem. This is my approach
"Peter makes $1/8 for every pencil he sells. Yesterday he made $3 by selling pencils, how many of them he sold? "
If we solved this question, we have to replace the ? for 24 and say Peter sold 24 pencils and made 24(1/8)=$3

The answer is A.
Step-by-step explanation:
Answer:
Volume of pyramid = 317 units³
Step-by-step explanation:
Volume do triangular pyramid = ⅓ × Base Area × height of pyramid
Base area = ½*bh = ½*8*14 = 56 units²
Height of pyramid = 17
Volume of pyramid = ⅓ × 56 × 17
Volume of pyramid = 317 units³ (to nearest whole number)
