You decide to buy a custom frame for a painting which measures 4 by 6 inches. If the framing material costs $2 per inch, what is the total cost of framing material?
Answer:
6 x 4 = 24 x $2 = $48
Step-by-step explanation:
The total cost of the rectangular frame is C = $240.
What is rectangle?A rectangle is a two-dimensional shape in which the opposite sides are parallel and equal to each other and all four angles are right angles.
Given that, a painting measures 4 by 6 inches, the framing material costs $2 per inch,
We need to find the total cost of framing material
The perimeter is given by:
P = 2x(L + W)
In this case, we know that the frame is 6 inches by 14 inches, then the perimeter will be:
P = 2x(6in + 14in)
P = 2x20in = 40in
Since, the framing material costs $6 per inch, then the total cost of the frame will be:
cost = 40x$6 = $240

Step-by-step explanation:
The area of a rectangular trampoline is 135 ft. The length of the trampoline is 6 ft
greater than the width of the trampoline. This situation can be represented by the
equation w2 +6w
135 = 0.
What is the width of the trampoline, in feet?
5 feet
15 feet
6 feet
9 feet
The width of the given trampoline is 9 feet, and which area is 135 square feet.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The equation w² +6w -135 = 0 can be factored as (w+15)(w-9) = 0.
Therefore, the solutions for w are w = -15 or w=9.
Since the width of the trampoline cannot be negative, we can conclude that the width of the trampoline is 9 feet.
To confirm this, we can calculate the length of the trampoline using the given information that the length is 6 feet greater than the width:
length = width + 6 = 9 + 6 = 15 feet
Then we can verify that the area is indeed 135 ft²:
area = length x width = 15 x 9 = 135 ft²
Therefore, the width of the trampoline is 9 feet.

2x + 5y = -24
3x - 5y = 14
Solve by elimination
y and x
Answer:
x = -2
y = -4
Step-by-step explanation:
The way systems of equations work is that you have to substitute to solve for a variable *(only one of the 2 ways to figure this out)*
so, we will use addition property of equality in a form to add the two equations together, since +5y and -5y added together will cancel out.
that would leave
5x = -10
divide both sides by 5
x = -2
Now that we know x = -2, we can plug in -2 into one of the equations to find y.
2 ( -2) + 5y = -24
-4 + 5y = -24
-4 + 4 + 5y = -24 + 4
5y = -20
y = -4
x = -2
y = -4

Andy’s dog weighs 27 pounds, which is 3/4 the weight of Seher’s dog. How many pounds does Seher’s dog weigh?
Answer:
20.25 lbs
Step-by-step explanation:
Multiply 27 by 3/4 or .75 to equal 20.25.
Answer:
36 pounds.
Step-by-step explanation:
Suppose Seher's dog weigh x pounds, here is an equation:
27=[tex]\frac{3}{4}[/tex]x
multiply 4 on both sides and dividing 3 on both sides, we get:
36=x
we flip this around:
x=36
So, Seher's dog weighs 36 pounds.
