The length of a rectangle is five inches less than three times its width. If the perimeter
of the rectangle is 150 inches, find the dimensions.
L=40 in. ; W=35 in.
L=60 in. ; W=45 in.
L=50 in. ; W=25 in.
L=55 in. ; W=20 in.
Answer:
L = 55 in, W = 20 in
Step-by-step explanation:
Hi there!
First we have to set up an equation for the length, which can be written as 3x - 5.
The formula for perimeter of a rectangle is 2l + 2w = p, so we can plug in some values here.
l = 3x - 5
w = x
[tex]2(3x-5) + 2(x) = 150[/tex]
Now we just have to solve!
[tex]6x - 10 + 2x = 150[/tex]
When we combine like terms and add ten to both sides, we are left with
[tex]8x = 160[/tex], which means x = 20
Using this, that means the width is 20
We can find the perimeter by plugging 20 in for x. [tex]l = 3(20) -5[/tex]
This means the length is 55.
Which ordered pair is a solution of the equation?
52 - 2y = 18
Answer: y=17
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
52−2y=18
52+−2y=18
−2y+52=18
Step 2: Subtract 52 from both sides.
−2y+52−52=18−52
−2y=−34
Step 3: Divide both sides by -2.
−2y
−2
=
−34

y=17

Answer:
22=90 23=15 24=60 25=0.75 26=70 37=$0.58
Step-by-step explanation:
22. So, we can divide 360 kmh by 4 hours
so 360/4 =90
So 90 kmh in 1 hr
23
So, we can divide 3 packages by $15
so 15÷3 = $5
So $5 per package
24 So, we can divide 720 m by 12s
So, 720/12= 60
60 m in 1 s
25
So, we can divide $4.50 by 6
So, we get $0.75
26
So, we can divide 210 words by 3 min
So, 210÷3=70
70 words per minute
27
So, we can divide 23.20 by 40l
So, 23.20÷40 = 0.58
$0.58

15:2 = x : 3 . Find x
Step-by-step explanation:
15/2=x/3
15×3/2=x
45/2=x
22.5=x
Answer:
22.5
Step-by-step explanation:
First find out the ratio x : 1
2 / 2 = 1
15 /2 = 7.5
Now you have this ratio
7.5 : 1
Now times each value by 3 to get the answer :
22.5 : 3
x = 22.5
hope this helps :)
Ren was trying to solve a system of linear equations. He correctly argued that he could replace one equation by the sum of that equation and a multiple of the other. H
produce a system that has the same solution as the original system.
To show this, Ren wrote down a system of equations. He then determined which other systems of equations would have the same solution as his original system. Rem
below.
-2x - 5y = -47
4x - 2y = -2
Complete the table below to determine which system(s) of equations has the same solution as the original system shown above. Choose Has the Same Solution or Do
for each system of equations.
Has the Same Solution Does Not Have the Same Solution
-14x + y = -41
4x - 2y = -2
-2x - 5y = -47
6x + 3y = 45
-2x - 5y = 47
8x - 5y = -8

Round off to the whole number
D= 19m
Explanation of results
So to find d you will use the trigonometry formula
So you are given the
Degree which is 39°
and the hypotenuse which is 30m
Using the sin θ = Opposite Side/Hypotenuse you are going to put in the numbers where they should go in the formula so,
[tex] \sin(39) = \frac{d}{30} [/tex]
then you are going to isolate d on the right by multiplying 30 on both sides.
It will look like
30 Sin 39
So, just put this in the calculator
Solve the following system of equations by substitution. Make sure to check your solution. x + y = 5 3x - y = -5
Answer:
(0.5)
Step-by-step explanation:
x + y = 5
3x - y = -5
Put "y" on one side to isolate
3x - y = -5
3x = y - 5
3x + 5 = y
Plug "3x + 5" in for "y" in the second equation
x + (3x + 5) = 5
4x + 5 = 5
4x = 0
x = 0
Plug "0" in for "x" in any one of the equations
0 + y = 5
y = 5
To check, plug in "0" for "x" into the first equation and make sure they get the same answers
3(0) - y = -5
0 - y = -5
y = 5
