The first side of a triangle is 2 inches shorter than three times the second side. The third side is 1 inch longer than twice the second side. If the perimeter of the triangle is 101 inches, how long is each side?
(Answer to get brainliest)
Answer:
17in, 49in, 35in
Step-by-step explanation:
I did this in my RSM homwork and it is correct.
First, I added the two inches shorter to the 101, then subtracted 1 longer and got 102.
then divide 102 by how many second lengths, 6. so 102 ÷ 6 = 17
17 is the second length.
3x17-2=49 (another length)
2x17+1=35 (last length)
and there is your answer!
First side : 49
Second side : 17
Third side : 35
What is the perimeter of a triangle?
If triangle has sides a, b, c , then the perimeter of that triangle will be P= a +b +c.
Now, according to the question
Let second side be (b) = x unit
then, First side will be (a)= 3x-2 unit
and Third side will be (c)= 2x + 1 unit
since , perimeter is 101
P = a + b + c
x + 3x -2 + 2x + 1 = 101
6x - 1 = 101
x= 17
hence , b = 17 unit
a= 3*17 - 2 =49 unit
c = 2*17 +1 = 35 unit

Write the equation of the line through the points (4, 5) and (12, 9)
Answer:
y = 1/2x + 3
Step-by-step explanation:
y2 - y1 / x2 - x1
9 - 5 / 12 - 4 = 4/8 = 1/2
y = mx+b
slope/m = 1/2
y = 1/2x + b
5 = 1/2(4) + b
5 = 2 + b
3 = b
y = 1/2x + 3
The equation of the line passing through the points (4, 5) and (12, 9) is x - 2y = -6
From the question,
We are to determine the equation of the line passing through the points (4, 5) and (12, 9)
Using the formula,
[tex]\frac{y-y_{1} }{x-x_{1}} = \frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
From the given information
x₁ = 4
y₁ = 5
x₂ = 12
y₂ = 9
Putting the parameters into the formula, we get
[tex]\frac{y-5}{x-4} =\frac{9-5}{12-4}[/tex]
Then,
[tex]\frac{y-5}{x-4} =\frac{4}{8}[/tex]
[tex]\frac{y-5}{x-4} =\frac{1}{2}[/tex]
Then,
[tex]x - 4 = 2(y-5)[/tex]
[tex]x - 4 = 2y-10[/tex]
[tex]x -2y = -10 + 4[/tex]
[tex]x -2y = -6[/tex]
Hence, the equation of the line passing through the points (4, 5) and (12, 9) is x - 2y = -6

Write 0.00034 as a multiple of a power of 10.
Answer:
3.4X10^-4
remove the zeros and add a decimal point after the first number eg.
0.00034 --> 34 --> 3.4
then add a x 10 eg.
3.4x10
then add a power- if the number is larger than 1 count the amount of zeros and add that as your power eg.
3400 -> 34 -> 3.4 -> 3.4x10^2
If the number is lower than one use a negative power eg.

Find the missing value in the follwing equivalent ratios: StartFraction 1 inch Over 2.54 centimeters EndFraction = StartFraction 4.5 inches Over question mark centimeters EndFraction To find how many centimeters are in 4.5 inches, you should 2.54 by 4.5 4.5 inches = centimeters
Answer:
11.43 centimeters
Step-by-step explanation:
Given the equivalent ratios :
StartFraction 1 inch Over 2.54 centimeters EndFraction = StartFraction 4.5 inches Over question mark
1 inch / 2.54 cm = 4.5 inch /?
Let missing value = x
1 inch / 2.54 cm = 4.5 inch /x
Cross multiply
1 inch * x = 2.54 * 4.5
1 inch * x = 11.43
x = 11.43 cm
Hence, missing value = 11.43 centimeters

A computer store pays sales associates $10 per hour
and managers $15 per hour. If the total hours
worked by the sales associates is 100 and the total
hours worked by managers is 50, how much will the
store pay in wages?
Answer:
They pay a total of $1750.
Step-by-step explanation:
You multiply the hours by the pay per hour SO,
Managers= $15 multiplied by the 50 hours they worked ($15 * 50hrs.) and get "$750"
Associates= $10 multipled by 100 hours ($10 * 100) and get "$1000"
Add the total sums ($750 + $1000) and get a total of $1750

3. Which equation can be used to find the measurement of ∠MNO, if the value of ∠LMN is 77 degrees? *
Answer:
154+2x=360
Step-by-step explanation:
Since the opposite angles are the same you add them together getting 154. You now have two unknown angles that are congruent which is expressed as 2x, and since a four sided shape always has an interior angle of 360 you set it equal. This gives you 154+2x=360.
Answer: It is the last one
154 + 2x = 360
Step-by-step explanation:
x= 103
154 + 2(103)= 360
154 + 206 =360

-2x+2y+3z=0
-2x-y+z=-3
2x+3y+3z=5
Answer:
x = 1 , y = 1 , z = 0
Step-by-step explanation:
Solve the following system:
{-2 x + 2 y + 3 z = 0 | (equation 1)
-2 x - y + z = -3 | (equation 2)
2 x + 3 y + 3 z = 5 | (equation 3)
Subtract equation 1 from equation 2:
{-(2 x) + 2 y + 3 z = 0 | (equation 1)
0 x - 3 y - 2 z = -3 | (equation 2)
2 x + 3 y + 3 z = 5 | (equation 3)
Multiply equation 2 by -1:
{-(2 x) + 2 y + 3 z = 0 | (equation 1)
0 x+3 y + 2 z = 3 | (equation 2)
2 x + 3 y + 3 z = 5 | (equation 3)
Add equation 1 to equation 3:
{-(2 x) + 2 y + 3 z = 0 | (equation 1)
0 x+3 y + 2 z = 3 | (equation 2)
0 x+5 y + 6 z = 5 | (equation 3)
Swap equation 2 with equation 3:
{-(2 x) + 2 y + 3 z = 0 | (equation 1)
0 x+5 y + 6 z = 5 | (equation 2)
0 x+3 y + 2 z = 3 | (equation 3)
Subtract 3/5 × (equation 2) from equation 3:
{-(2 x) + 2 y + 3 z = 0 | (equation 1)
0 x+5 y + 6 z = 5 | (equation 2)
0 x+0 y - (8 z)/5 = 0 | (equation 3)

{-(2 x) + 2 y + 3 z = 0 | (equation 1)
0 x+5 y+0 z = 5 | (equation 2)
0 x+0 y+z = 0 | (equation 3)
Divide equation 2 by 5:

3x + -18x + 26x + -11x
Answer:
0
Step-by-step explanation:
First, you have 3x and subtract 18x from it. This gives you -15x.
Then you have positive 26x, so you add 26x onto -15x.
After doing so, you have a positive 11x.
Now you need to subtract 11x from 11x.
Your final answer is 0! (No need to put x since it is just zero.)

Answer:
B, 2x^2 - 4x + 8
Step-by-step explanation:
Given an area of 4x^2 - 8x + 16, and a length of 2, we can use the area formula of length, and width to find the area:
Length × Width = Area
Given these values, rearrange the formula to find the width:
Width = Area / Length
Then just substitute the values, and
simplify the expression:
Width = (4x^2 - 8x + 16) / 2
Width = 2x^2 - 4x + 8

Step-by-step explanation:
During a special sale, all video games cost $26 and all movies cost $14. Derrick plans to spend some or all of his $220 in birthday money on these movies and video games. Let "x" represet the number of games Derrick can buy and "y" represent the number of movies he can buy. Write the inequality that describes this situation in standard form.
Answer:
[tex]13x+7y\leq 110[/tex]
Step-by-step explanation:
Let "x" represents the number of games Derrick can buy and "y" represents the number of movies he can buy.
Cost of all video games = $26
Cost of all movies cost = $14
Total amount with Derrick = $220
So,
cost of [tex]x[/tex] video games + cost of [tex]y[/tex] movies [tex]\leq[/tex] 220
Therefore, the inequality is [tex]26x+14y\leq 220[/tex]
Divide this inequality by 2
[tex]13x+7y\leq 110[/tex]

A family bought a total of 16 adult and child tickets to a magic show. Adult tickets are $10.50 each and child tickets are $7.50 each. The family paid a total of $141. How many of adult tickets, a, and child tickets, c, did they buy?
9514 1404 393
Answer:
7 adult tickets9 child ticketsStep-by-step explanation:
Using the variables defined in the problem statement, we can write the equations ...
a + c = 16 . . . . . . . . . . . . number of tickets bought
10.50a +7.50c = 141 . . . cost of tickets bought
Substituting for c in the second equation, we get ...
10.50a +7.50(16 -a) = 141
3.00a +120 = 141 . . . . . . . . simplify
3a = 21 . . . . . . . . . . . subtract 120
a = 7 . . . . . . . . divide by 3
16 -a = c = 9 . . . . . . . find the number of child tickets
They bought 7 adult tickets and 9 child tickets.
_____
If you examine the solution, you see that the number of adult tickets (the higher priced item) is the quotient of the difference between the actual expenditure (141) and the amount that would have been spent on all child tickets (16×7.50=120), and the difference in ticket prices (10.50-7.50=3.00). Knowing this, you can often work problems of this kind in your head.
Find four numbers if their ratio is 9:11 and their difference is 6.
Answer:
Step-by-step explanation:
Let the larger number = y
Let the smaller number = x
x/y = 9/11
y - x = 6
Add x to both sides of the second equation
y = 6 + x
Substitute into the first equation
x/(x + 6) = 9/11
Cross multiply
11x = 9(x + 6)
Remove the brackets
11x = 9x + 54
Subtract 9x from both sides.
2x = 54
x = 54/2
x = 27
y = 27 + 6
y = 33
