Let,
digital cameras be "x"
video cameras be "y"
Now,
According to the question,
5x + 3y = $3,213..................................................equation (1)
y = 4x..................................................................equation (2)
Taking equation (1)
5x + 3y = $3,213
Substituting the value of "y" from equation (2), we get,
5x + 3(4x) = $3,213
5x + 12x = $3,213
17x = $3,213
x = $3,213 / 17
x = $189
Taking equation (2)
y = 4x
Substituting the value of "x", we get,
y = 4 ($189)
y = $756
Now,
John buys a digital and a video camera. So, it costs him ($189 + $756) = $945
Answer:
Absolute value equation: |x - 13| = 5
Step-by-step explanation:
The midpoint between 8 and 18 is;
(8 + 18)/2 = 26/2 = 13
This means that the distance between 13 and either 8 or 18 will be 5.
Now, the absolute value equation will have to say that the distance between x and 13 is 5.
Thus, plugging those numbers into the pattern of |x - m| = b. Where m is the midpoint and b is the distance from midpoint to either values of x.
This gives us the absolute value equation: |x - 13| = 5
