Answer:
37 chairs.
Step-by-step explanation:
Let x be number of chairs that Liam has and y = number of chairs in 1 row.
Then x = 8y + 5
and x = 6y + 13 Subtracting:
0 = 2y - 8
2y = 8
y = 4.
and x = 8(4) + 5 = 37 chairs (answer).
Hope this helps.
Answer:
$31.50
Step-by-step explanation:
In this problem we need to write an equation to represent the situation and then solve for the variable. We first need to define a variable that makes sense to the problem, the variable should represent what we are solving for.
x=cost of a single pair of jeans
3x=94.50
Now, we need to solve for x to find the cost of a single pair of jeans.
3x/3=94.50/3
x=31.50
The cost of a single pair of jeans is $31.50

Answer:
A
Step-by-step explanation:
A. (1,3) and (6,3) have the same y-coordinate, so the distance between them is the difference of the x-coordinates.
distance = 6-1 = 5
:::::
B. (3,5) and (1,5). Again, the same y-coordinate. Distance = 3-1 = 2 ≠ 5
:::::
C. distance = 5-1 = 4 ≠ 5
:::::
D. distance = 3-2 = 1 ≠ 5
Equation R: -3y = -3x - 9
Equation S: y = x + 3
Replace y in Equation R with equation S:
-3(x+3) = -3x - 9
Use distributive property:
-3x -9 = -3x -9
Because both sides of the equation are identical x can be any number and they would still be equal.
This means there are Infinite solutions.
