Step-by-step explanation:
Given:
Two Equations
y = x + 5 ..................(1)
y = (3/2) x - 5 ...................(2)
Both are considered as Equation (1) and (2) respectively,
Equating the equation 1 and 2, we get
⇒ x + 5 = (3/2) x - 5
⇒ x - (3/2) x = - 5 - 5
⇒ (2x - 3x) /2 = - 10
⇒ - x = - 20
⇒ x = 20
Now substituting "x = 20" in equation (1), we get
⇒ y = 20 + 5
⇒ y = 25
Thus, we get the value of x = 20 and value of y = 25.
Answer:
Step-by-step explanation:
This is just a perfect square
<span>Let the number of chairs in a row be x, then the total number of chairs is 9x + 3 = 7x + 19. i.e. 9x + 3 = 7x + 19; 9x - 7x = 19 - 3; 2x = 16 x = 16/2 = 8. Thus there are 8 chairs in each row. Therefore, the total number of chairs is given by 9(8) + 3 = 72 + 3 = 75.I hope that my answer is helpful! Let me know if you need something more :)</span>
Answer:
C. 6
Step-by-step explanation:
to divide by a fraction multiply by the recirpocal of that fraction.
8/3 ÷ 9/4
reduce the numbers with GCF 4 which equals 2/3 x 9
reduce the numbers with GCF 3 which equals 2x3= 6
