the lengths of the sides of a triangle are 2x+1, 3x-2, and 4x-5. what is the perimeter in terms of x
Answer:
Step-by-step explanation:
2X + 1 + 3X - 2 + 4X - 5 = 180
9X - 6 = 180
9X = 174
9 = 174
ـــــــــــــــــــــ
9 9
X = 19.333
The perimeter of the triangle in terms of x given the three side lengths is 9x - 6.
What is the perimeter?
A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees.
The perimeter of a triangle = sum of the side lengths
(2x + 1) + (3x - 2) + (4x - 5) = 9x - 6

Write 3 and 3/4 as a decimal. Is it repeating or terminating?
Answer:
3.75, Terminating
Step-by-step explanation:
To answer this, we simply have to find what 3/4 is as a decimal. So, we know that in order to make 4/4, or 1, we need 4 parts. Let's say that 4/4 would equal 100, so we need to divide 100 into 4 parts:
100 / 4 = 25
Now, to find what 3/4 is, all we have to do is multiply 25 by 3:
25 * 3 = 75
And that is our decimal form, we just need to add the 3:
3.75, and since .75 doesn't keep on repeating, it just stops at .75, this is a terminating decimal
Hope this helps! :)
What is the slope of the line that contains the points (-2,5) and (6,-3)? O A. 1 O B. -8 O C. -1 O D. 8
Answer:
-1
Step-by-step explanation:
Find the slope using the slope formula
m = (y2-y1)/(x2-x1)
= (-3-5)/(6 - -2)
= (-3-5)/(6+2)
= -8/8
= -1
Answer:
The answer is option CStep-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-2,5) and (6,-3)
The slope is
[tex]m = \frac{ - 3 - 5}{6 + 2} = - \frac{8}{8} = - 1[/tex]
We have the final answer as

kqw1qw1lo12
Step-by-step explanation:
Find the equation of the line. Use exact numbers.
Answer:
y=-3/2x+3
Step-by-step explanation:
The slope is -3/2x because it's going down 3 and to the right 2.
And it intercepts the y-axis at 3. Thus, 3 is the y-intercept.
Answer:
y = -3/2 x +3
Step-by-step explanation:
We can use the slope intercept form
y = mx+b where m is the slope and b is the y intercept
The y intercept is 3
Now to find the slope
Pick two points on the line
( 0,3) and ( 2,0)
m = ( y2-y1)/(x2-x1)
= ( 0-3)/(2-0)
= -3/2
The equation of the line is
y = -3/2 x +3

Step-by-step explanation:
I got the same thing as the other person, but typing it out would take forever just to give you the same result.
You do use a technique called rationalizing a denominator to eliminate the radical. The point of rationalizing a denominator is to make it easier to understand what the quantity really is by removing radicals from the denominators.
1) ( 6+[tex]\sqrt{6}[/tex] ) / 2

Answer:
y+x=600
Step-by-step explanation:
Answer:
Step-by-step explanation:
first step : you put it in y form
y<600-x
then put the x so that the value of x+y do not exceed 600
since the sign is < and not ≤ then the line is dotted and not solid
Solve the following for y: -6x+2y=8(5 points)
Y= -6x+8
Y= 6x+8
Y= -3x+4
Y= 3x+4

John wants to send a letter to peter who lives on tesla street john does not remember the house number however he knows that it has 4 digits it is a multiple of 5 and 7 and that that the last digit is 0 what is the minimum number of letters that john has to send to be sure that peter receives his letter
Answer: 137 letters.
Step-by-step explanation:
The data is:
The number has 4 digits.
The number is a multiple of 5
The number is a multiple of 7
The last digit is a 0.
Then, let's find all the possible numbers that met these conditions.
Our number can be formed with 4 digits, A, B, C and D.
D is the last one, so we have D = 0.
So the number is: ABC0
We know that all the numbers that end with 0 are multiples of 5, so that condition does not matter.
Now, a number is divisible by 7 if:
Take the last digit of the number, double it and subtract it to the remaining number, if the result is multiple of 7, then the initial number is a multiple of 7.
In this case the last digit is 0, so when we double it and subtract it, we actually are not changing the other 3 digits.
Then we have that:
ABC must be a multiple of 7.
So now our problem reduces to find the number of 3-digit numbers that are multiples of 7.
The first multiple of 7 that has 3 digits is:
7*15 = 105.
And the largest possible 3 digit number is 999, now let's try to divide it by 7 to see if this is also a multiple of 7.
999/7 = 142.7
the quotient is not integer, so 999 is not a multiple of 7.
The next option is 998, we can do the same here:
998/7 = 142.6
And so on, we will find that the largest 3 digit multiple of 7 is:
994, such that:
7*152=994.
Then we have:
Smallest: 7*15 = 105
Largest: 7*152 = 994.
Then the number of multiples of 7 between 999 and 100 will be equal to the difference between the quotients between the multples and 7.
105/7 = 15
994/7 = 152
152 - 15 = 137
So we have 137 multiples of 7 with 3 digits.
Then we have 137 4-digit numbers, that end with a zero and also are divisible by 5 and 7.
So John must send 137 letters if he wants to be shure that Peter will get the card.

How do you write 89,000 in scientific notation
Answer:
8.9 × 10^{4}
Step-by-step explanation:
Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10b.
Follow the steps below to see how 89,000 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 89,000
New Number: 8.9000
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 8 . 9 0 0 0
Decimal Count: 1 2 3 4
There are 4 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 8.9 (Please notice any zeroes on the end have been removed)
b = 4
Now the whole thing:
8.9 x 10^{4}
Step 4
Check your work:
10^{4} = 10,000 x 8.9 = 89,000
