Answer:
x=10.25
Step-by-step explanation: since they're congruent, that's mean they're equal. Set both of the equation equal to each other and solve for x
5x+24=9x-17
24=4x-17
41=4x
x=10.25
which shows the list below in order from greatest to least. 3.4848, -3 19/20, √11, -3.58, 362%
please help! find QPR
Answer:
m∡QPR = 25°
Step-by-step explanation:
solve for 'x':
8x + 7 + 9x + 16 = 40
17x + 23 = 40
17x = 17
x = 1
m∡QPR = 9(1) + 16

Weird question but, whenever you divide by 1/4 or multiply by 4/1, will you always get the same answer.
(25 points if you answer this.)
Answer:
yep
Step-by-step explanation:
when you divide a fraction u can use the KCF method which is basically:
(keep) the first fraction the same
(change) the division sign in the middle to a multiplication sign
(flip) the second fraction
basically because you have to flip the 1/4 when you divide it, it'll be the same as a 4/1 anyways

8th grade teachers and students from M.I.T went on a field trip to an zoo. Tickets
were $5.00 each for teachers and$3.50 each for students, and the group paid
$51.50 in total.A few weeks later, the same group visited a natural history
museum where the tickets cost $20.00 each for teachers and $8.50 each for
students, and the group paid $156.50 in total.
Find the number of teachers and students on the field trips.
A 4 Teachers and 9 Students
4 Teachers and 10 Students
3 Teachers and 9 Students
D None of the above
As there are multiple answers going with trial and error seems good in this case.
A
5.00 + 5.00 + 5.00 + 5.00 = 20.00
3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 = 31.5
20.00 + 31.5 = 51.5
B
5.00 + 5.00 + 5.00 + 5.00 = 20.00
3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 = 35.00
20.00 + 35.00 = 55.00
C
5.00 + 5.00 + 5.00 = 15.00
3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 = 31.5
15.00 + 31.5 =46.5
Knowing that for the first one all A,B, and C were wrong we can determine that D is the answer. But wait if I made one mistake and didn't understand if $156.5 is equivalent to $156.50 that would mean A is correct.
Always recheck your answers and good luck,

The longest side of a triangle is 8 more units than the shortest side. The third side is 4 times the length of the shortest side. If the perimeter of the triangle is 32 units, write and solve an equation to find the length of all 3 sides of the triangle
Answer:
10 3/4, 4 3/4, and 9 1/2
Step-by-step explanation:
We're going to let x represent the length of the longest side. The perimeter is
x +(x-6) +2(x-6) = 25
4x -18 = 25
4x = 43
x = 43/4 = 10 3/4
Then x-6 = 4 3/4.
Multiply that two to get 8 3/2 = 9 1/2

The Murphy family is on a road trip. On the first day, they traveled 30% of their total distance. On the second day, they traveled another 1 4of the total distance. What fraction of the total distance do they have left after
Answer:
5/12
Step-by-step explanation:
Total distance travelled = 30% + 1/4
To add these numbers, convert 30% to fraction
30% = 1/3
1/3 + 1/4 = 7/12
Remaining distance = 1 - 7/12 = 5/12

The total cost of a compact disc, including a 6% sales tax, is $14.31.
What is the price before the tax?
$13.50
$13.45
$13.44
$15.17
The cost of a compact disc before the sale tax is $13.45. The correct option is B.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that the total cost of a compact disc, including a 6% sales tax, is $14.31.
The cost before the sale tax will be calculated as,
Cost = 14.31 x ( 1 - 0.06 )
Cost = 14.31 x 0.94
Cost = $13.45

Answer:
first question: decrease - second question: 34
Step-by-step explanation:
first question: to find the mean, you need to add all of the numbers together and divide the sum of those by the amount of numbers you added together. in this question, it would be
73+79+96+84=332 -> 332/4=83 is the mean for the 1st set of numbers
(1) (2) (3) (4)
the question asks what happens after the next test score is added in, for this, you will do the same steps as before except you add in the 80 for her fifth test and then divide by 5 instead of 4, because you have another number being added.
73+79+96+84+80=412 -> 412/5=82.4 is the mean for the 2nd set of numbers
the second set of numbers, after the fifth test score is added in, is lower than the first set of numbers. therefore, the mean decreases
second question: same concept, except on a dot plot. a dot above a number means that there is one of those numbers that should be counted. this means since there are 2 dots above the 30, there are 2 30s being added to the rest of the numbers. in this dot plot, the numbers being added are
30+30+32+32+34+38+38+38=272 -> 272/8=34 is the mean

The midpoint of overline AB is M(0, - 7) . If coordinates of A are (- 2, - 6) , what are the coordinates of B?
Given:
The midpoint of overline AB is M(0, - 7) .
The coordinates of A are (- 2, - 6).
To find:
The coordinates of point B.
Solution:
Let the coordinates of point B are (a,b).
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
The midpoint of overline AB is M(0, - 7). Using the midpoint formula, we get
[tex]M=\left(\dfrac{-2+a}{2},\dfrac{-6+b}{2}\right)[/tex]
[tex](0,-7)=\left(\dfrac{-2+a}{2},\dfrac{-6+b}{2}\right)[/tex]
On comparing both sides, we get
[tex]\dfrac{-2+a}{2}=0[/tex]
[tex]-2+a=0[/tex]
[tex]a=2[/tex]
And,
[tex]\dfrac{-6+b}{2}=-7[/tex]
[tex]-6+b=-14[/tex]
[tex]b=-14+6[/tex]
[tex]b=-8[/tex]
Therefore, the coordinates of point B are (2,-8).
