Answer:
The value of x = -1
Step-by-step explanation:
=> 3x-5=2(-x-5)
=> 3x - 5 = -2x - 10
=> 3x + 2x = -10 +5
=> 5x = -5
=> x = -5/5
=> x = -1
Answer:
Step-by-step explanation:
Compact cars:
24 divided by 4 = 6
6 cars for 24 people
SUV's:
24 divided by 6 = 4
4 SUV's for 24 people
" always " is the wrong word....should be sometimes
usually the LCM is greater....
example : 2 and 4.....LCM = 8, GCF = 2
3 and 6....LCM = 12, GCF = 3
However, if ur 2 numbers are the same...
2 and 2.....LCM = 2 and GCF = 2
4 and 4....LCM = 4 and GCF = 4
Answer:
width = 150 yards
length = 200 yards
Step-by-step explanation:
Using the information given to us, we can make the following two equations:
2L + 2W = 700
L = W + 50
where L is the length in yards and W is the width in yards. This could treat these two equations as a system of linear equations. There are multiple ways to solve a system of linear equations, but I am going to solve this by substitution. Before doing that, I am first going to simplify the first equation, as it will make solving the system easier.
2L + 2W = 700
Divide both sides by 2.
L + W = 350
Since L = W + 50, we can substitute W + 50 for L in the equation L + W = 700.
(W + 50) + W = 350
2W + 50 = 350
2W = 300
W = 150
Now that we found what W is, we can solve for L by plugging 150 into either one of the equations. I am going to plug it into the equation L = W + 50.
L = 150 + 50
L = 200
Now we found what L is. So now we know that the width is 150 yards and the length is 200 yards.
I hope you find my answer and explanation helpful. Happy studying. :)
