A rectangle has a perimeter of 48 inches. If twice the length decreased by three is equal to three times the width, the find the length and the width
Answer:
Length= 15, width= 9Step-by-step explanation:
perimeter of a rectangle P= 2(L+W)
L= length
W= width
48=2(L+W)---------------(1)
twice the length= 2×L= 3L
decreased by three= 2L-3
three times the width= 3×W= 3W
twice the length decreased by three is equal to three times the width
2L-3= 3W-------------------(2)
solving equation one and two simultaneously
from equation (2)
3W= 2L-3
W=2L/3-3/3
W= 2L/3 - 1----------(3)
substitute equation (3) into equation (1)
48=2(L+2L/3-1)
48=2L+4L/3-2
48×3=6L+4L-6
144=10L-6
10L=144+6
10L=150
dividing bothsides by 10
L= 15
substitute L= 15 into equation (2)
2L-3=3W
2(15)-3=3W
30-3 = 3W
27= 3W
3W= 27
dividing bothsides sides 3
3W=27/3
W=9
therefore, Length= 15, width= 9Directions: Using the digits 0-9, no more than once each, fill in the boxes to make the statement true:
The equation [tex]\frac{5-3-2}{1+4+6+7+8+9}[/tex] = 0 is true
What is fraction?
In arithmetic, a number expressed as a quotient, in which a numerator is divided by a denominator.
Using digits 0 to 9, no more than once each.
we want to place them in such a way that the division will be zero.
As we know that a quotient is equal to zero iff the numerator is equal to zero and the denominator other than zero.
So if we put some numbers on the numerator in such a way by adding them gives 0.
So, 5 - 3 - 2 = 0
Use all the other numbers in the denominator.
[tex]\frac{5-3-2}{1+4+6+7+8+9}[/tex] = 0
which is true.

Explain how to use equivalent ratios to simplify ratios.
i need this asap or i’m gonna get in trouble.
The equivalent ratio of the given ratio of 8:2 is 4:1. Hence, the ratio of 8 to 2 is equivalent to the ratio of 4:1.
What is an equivalent ratio?When we compare ratios, equivalent ratios are the ones that are the same. To see if two or more ratios are equivalent, they can be compared to one another.
Given information:
The ratio given in the question is 8:2.Now, we need to calculate the equivalent ratio of the given ratio.As we know that the equivalent ratio is defined as the ratio which is having the same proportion as the given ratio.
Now, using the division property of the ratio, We will divide the given ratio with the same number on both sides:
Hence, by dividing the given ratio by 2 we get the ratio as 4:1.
Therefore, the equivalent ratio of the given ratio of 8:2 is 4:1. Hence, the ratio of 8 to 2 is equivalent to the ratio of 4:1.

How to graph the system of inequalities?
Here we have two inequalities:
x < 2
y ≥ - 3
To graph the first one, we need to shade all the region at the left of the line x = 2, such that the line must be dashed, because the points on the line are not solutions.
For the second inequality, we need to shade all the regions above the line y = -3, this time the line must be solid, because the points on the line are solutions.
Then the graph of the inequalities is the one you can see below. The intersection of the shaded regions is the solution of the system of inequalities.

a student walks 8 steps east 6 steps northeast 9 steps north west what is her displacement? include magnitude and direction
The displacement is 18.03 steps, and the direction is 47.25°
How to get the displacement?
We know that displacement is the difference between the final position and the initial position.
We assume the initial position (0, 0). Let's define the positive x-axis as the east and the positive y-axis as the north.
First, the student moves 8 steps east, so she is at:
(0 + 8, 0)
Then she moves 6 steps northeast, so the new position is:
(6*cos(45°) + 8, 6*cos(45°))
Finally, she moves 9 steps due north, so we have:
(6*cos(45°) + 8, 6*cos(45°) + 9)
Then the final position is:
(12.24, 13.24)
So the displacement is:
D = (12.24, 13.24) - (0, 0) = (12.24, 13.24)
The magnitude of the displacement is:
[tex]|D| = \sqrt{12.24^2 + 13.24^2} = 18.03[/tex]
So the magnitude is 18.03 steps.
And the direction is given by the arctangent of the quotient between the y-component and the x-component:
[tex]\theta = Arctg(13.24/12.24) = 47.25 \°[/tex]
