solve the inequality -5(x-7)<15 algebraically for x.

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

hope this helps!

Step-by-step explanation:

Avni's ratio = 5/9

Money of Avni = 36*5/9= 20

Namitha's ratio= 4/9

Money of namitha = 36*4/9= 16

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).

1,036,800 in year 2018

Step-by-step explanation:

20% of 600,000 is 120,000

120,000+600,000=720,000

720,000 in year 2016

20% of 720,000 is 144,000

720,000+144,000=864,000

864,000 in year 2017

20% of 864,000 is 172,800

172,800+864,000=1,036,800

1,036,800 in 2018

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

I hope this helped! :)

Answer:

-27-4=3x+3

-30-3=3x

X=-11

Answer:

x > 4

Step-by-step explanation:

multiply by 6 to both sides to take out the fraction, leaving u with :

7x - 4 > 4(6)

7x - 4 > 24

    +4     +4

7x > 28

divide by 7 to isolate the x

x > 4

Step-by-step explanation:

x + 62 = 90

because they are complementary angles

I don't see any r

but I guess since they're complementary it would be 90 - 62

Answer:

Complementary angles

x = 28°

Step-by-step explanation:

Angle relationship = Complementary angles

x = 90° - 62° = 28°

Answer:

The answer is

[tex]x = 12 \\ y = 20 \\ z = 15[/tex]

Step-by-step explanation:

By using Pythagoras low

Then we can find that

[tex] {y}^{2} = {x}^{2} + {16}^{2} \\ {z}^{2} = {x}^{2} + {9}^{2} \\ {y}^{2} + {z}^{2} = {25}^{2} \\ then \\ {x}^{2} + {9}^{2} + {x}^{2} + {16}^{2} = {25}^{2} \\ 2 {x}^{2} = 288 \\ x = 12 \\ By \: substituting \: x \: into \: the \: previous \: equations \\ then \: \\ y = 20 \\ z = 15[/tex]

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

m∡QPR = 25°

Answer:

x=5

y=-17

Step-by-step explanation:

basically what I did was:

1) I multiplied the first equation by 4 , solved for x

2) I used the value of x that i found and substituted in one of the equations to find y

Answer:

$511.575

Step-by-step explanation:

Given data

P=$475

R=3.8%

T= 2 years

Compound interest

A=P(1+r)^t

substitute

A=475(1+0.038)^2

A=475(1.038)^2

A=475*1.077

A=511.575

Hence the final amount is $511.575

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

Answer:

Answer is y=6 (option C).

Step-by-step explanation:

|10 - 5y| = 20

First equation is just as written for first solution:

10 - 5y = 20

Subtract 10 from both sides to eliminate the 10.

-5y = 10

divide both sides by -5 to eliminate the -5 and isolate the y.

y = -2

Distribute negative sign through equation for a second solution.

|10 - 5y| = 20

-(10 - 5y) = 20

-10 + 5y = 20

Add 10 to both sides to eliminate the 10.

5y = 30

divide both sides by 5 to eliminate the 5 and isolate the y.

y = 6

y = 6 is the only answer listed in the 4 options.

Answer:

Step-by-step explanation:

see the image below

Step-by-step explanation:

The side that is adjacent to 60 degree and 90 degree is the shortest side.

If u know the hypoutnese you can divide it by 2 to find the shortest side. for example if the hypotenuse is 10 then the shortest side is 5

If you know the other leg you can simply just remove the entire radical and just keep the whole number to find the length of the shortest side.

The side that his the adjacent to the 30 degree and 90 degree angle is the second longest side of the triangle.

If u know the shortest side, just multiply the radical

[tex] \sqrt{3} [/tex]

to the whole number.

If you know the hypotunese, divide the hypotenuse by 2 and then multiply the radical to find the length of the second shortest side

Finally, the hypotunese is the largest side. It is the slanted side length that is adjacent to the 30 and 60 triangle.

If you know the shortest side, just multiply the side length by 2 to get the hypotenuse.

If you know the other leg, remove the radical and keep the who the number and multiply the whole number by 2.

E.x if the second longest side length is

[tex]5 \sqrt{3} [/tex]

Remove the radical so it becomes

[tex]5[/tex]

then multiply it by two to find the hypotunese.

[tex]5 \times 2 = 10[/tex]
