Answer:
Step-by-step explanation:
1) Olivia is x years old. Peyton is 6 years older than Olivia. This means that Peyton's age is (x + 6) years Three times Peyton's age is equal to 24. The equation that could be used to solve for Olivia's age is
3(x + 6) = 24
2) 3x + 18 = 24
Subtracting 18 from the left hand side and the right hand side of the equation, it becomes
3x + 18 - 18 = 24 - 18
3x = 6
Dividing the left hand side and the right hand side of the equation by 3, it becomes
3x/3 = 6/3
x = 2
3) Peyton's age = x + 6 = 2 + 8
= 8 years
Answer:
what do you mean by that question
Take the point (10,5)
5 = constant / 10
constant = 5*10 = 50
also for the point (4 , 12.5) constant = 4*12.5 = 50
Answer is 50
The perimeter of the park is 3x^2 + 37x - 4
<h3>How to determine the perimeter?</h3>
The side lengths of the triangular park are:
10x + 3x^2 - 8, 12x and 15x + 4
Add these sides to determine the perimeter
P = 10x + 3x^2 - 8 + 12x + 15x + 4
Collect the like terms
P = 3x^2 + 10x + 12x + 15x - 8 + 4
Evaluate the sum
P = 3x^2 + 37x - 4
Hence, the perimeter of the park is 3x^2 + 37x - 4

Answer:
x = (-629)/4
Step-by-step explanation:
Solve for x:
-2 x - 18 = 4 x - 2 x + 611
4 x - 2 x = 2 x:
-2 x - 18 = 2 x + 611
Subtract 2 x from both sides:
(-2 x - 2 x) - 18 = (2 x - 2 x) + 611
-2 x - 2 x = -4 x:
-4 x - 18 = (2 x - 2 x) + 611
2 x - 2 x = 0:
-4 x - 18 = 611
Add 18 to both sides:
(18 - 18) - 4 x = 18 + 611
18 - 18 = 0:
-4 x = 611 + 18
611 + 18 = 629:
-4 x = 629
Divide both sides of -4 x = 629 by -4:
(-4 x)/(-4) = 629/(-4)
(-4)/(-4) = 1:
x = 629/(-4)
Multiply numerator and denominator of 629/(-4) by -1:
Answer: x = (-629)/4
