Solve the equation:
-7(-3n+3) = -21 +21n

Answer:

y = - 9

Step-by-step explanation:

Substitute in -1 for x

8(-1) - 2y = 10

-8 - 2y = 10

Subtract -8 from both sides

-8 - (-8) cancels out to 0

10 - (-8) = 18

We are left with:

-2y = 18

Divide by -2 on both sides.

-2y/-2 = y

18/-2 = -9

y = -9

Answer:

[tex](x,y) = (17,16)[/tex]

Step-by-step explanation:

Given

[tex]T(x_1,y_1) = (4, 1)[/tex]

[tex]U(x_2,y_2) = (30, 11)[/tex]

[tex]V(x_3,y_3) = (17, 36)[/tex]

Required

Determine the coordinates of the centroid

The coordinate is calculated as:

[tex](x,y) = (\frac{1}{3}(x_1+x_2+x_3),\frac{1}{3}(y_1+y_2+y_3))[/tex]

Substitute values for x's and y's

[tex](x,y) = (\frac{1}{3}(4+30+17),\frac{1}{3}(1+11+36))[/tex]

[tex](x,y) = (\frac{1}{3}(51),\frac{1}{3}(48))[/tex]

[tex](x,y) = (\frac{51}{3},\frac{48}{3})[/tex]

[tex](x,y) = (17,16)[/tex]

Hence, the coordinates of the centroid is (17,16)

Answer:

Step-by-step explanation:

Given that X -  the distribution of heights of male pilots is approximately normal, with a mean of 72.6 inches and a standard deviation of 2.7 inches.

Height of male pilot = 74.2 inches

We have to find the percentile

X = 74.2

Corresponding Z score = 74.2-72.6 = 1.6

P(X<174.2) = P(Z<1.6) = 0.5-0.4452=0.0548=5.48%

i.e. only 5% are below him in height.

Thus the malepilot is in 5th percentile.

Answer:

x = -38/3

Step-by-step explanation:

lol

Simplify 5 + 37 = 42

42 = 4 - 3x

Subtract 4 from both sides

42 - 4 = -3x

Simplify 42 - 4 = 38

38 = -3x

-38/3 = x

MAY I PLEASE HAVE BRAINLIEST!!???

Answer: So let’s switch the denominater to 12s 5 x 2 is 10/12. 1/2 is 6/12. 3/4 is 9/12. So 10/12 + 6/12 + 9/12 = 25/12 or 2 1/12 Hope this helps you

Step-by-step explanation:

Answer:

25/12

Step-by-step explanation:

12

2. Find each fraction with a denomntor of 12

5/6 to 10/12

1/2 to 6/12

3/4 to 9/12

Answer:

4.123

Step-by-step explanation:

Answer: 4.12

"you should rlly get to know this"

btw ^2 means to the power to 2

Step-by-step explanation:

a^2 + b^2 = c^2

in this case, u don't have "a"

the slanted side is "c"

a^2 + 8^2 = 9^2

a^2 + 64 = 81

a^2 = 81 - 64

a^2 = 17

         ___

a = _/ 17

a = 4.12

Answer:

A. 480

Step-by-step explanation:

ok so first you multiply 1200 by 40 percent

we gonna change 40 percent to a decimal which will be 0.40

then multiply which will get 480

Answer:

720 children

Step-by-step explanation:

40% were adults

So 60% were children

60% of 1200 is 720 children (0.60 x 1200)

Answer:

Below

Step-by-step explanation:

x=[tex]\frac{1-20g}{10(1-4g)}[/tex]

Answer:

using BODMAS=(4x-2)=(2x)

10x-10g(2x)=

10x=10+(2x)=

10x=20x

divide both sides by 10

10x/10=20x/10

x=20/10

x=2

Answer:

$18.28

Step-by-step explanation:

Step one:

given data

Kate had a sum of money,she spent 1/8 of the money on a skirt and the remaining amount on a handbag

let the total money be x

so  mathematically

x-1/8*x= 16

solve for x

x-x/8= 16

8x-x/8= 16

7x/8=16

cross multiply

7x= 8*16

7x=128

divide both sides by 7

x=128/7

x=$18.28

Answer:

Step-by-step explanation:

a) If x = 2y, then x + y

In terms of y

2y + y

3y

b) If x = 3y, then 2xy

In terms of y

2(3y)(y)

6y²

c) If a = 2b and b = 3, then a + b

a + b

2b + b

2(3) + 3

9

d) If p = 3q and q = 2, then p-q​

p-q

3q - q

2q

Answer:

Time remain = 85/24 hours

Step-by-step explanation:

Given:

Total time taken by April = [tex]7\frac{3}{8}[/tex] hours

Time she already drive = [tex]3\frac{5}{6}[/tex] hours

Find:

Time remain

Computation:

Time remain = Total time taken by April - Time she already drive

Time remain = [tex]7\frac{3}{8}[/tex] hours - [tex]3\frac{5}{6}[/tex] hours

Time remain = 85/24 hours

Answer:

w=5

Step-by-step explanation:

Solve for W by getting it by itself.

1. Divide both sides by -4.

(w + 1)= -24/-4

2. Simplify

(w + 1)= 6

3. Subtract 1 from both sides.

w= 6-1

w= 5

Answer:

7(3b + 4c)

Step-by-step explanation:  Find the GCF then factor it out from the expression.

Answer:

m = 13/30

Step-by-step explanation:

2/5 + m = 5/6

m + 2/5 = 5/6

m + 2/5 - 2/5 = 5/6 - 2/5

m = 13/30

Answer:

M = 13/30

Step-by-step explanation:

2/5 + m = 5/6

Subtract 2/5 from both sides

m = 13/30

Hope its right

the area of shape below is 42

The area of the shape is 396 square cm.

A rectangle is one of the types of quadrilaterals in which all four angles are right angles or equal to 90 degrees. It is four-sided polygon in which the opposite sides are parallel and equal to each other.

For the given situation,

The diagram shows the polygon.

Let us consider the polygon as two rectangles as opposite sides are parallel and all the angles are right angle as shown below.

The rectangle ABCD has the dimensions length is 10 cm and breadth is 27 cm.

The rectangle DEFG has the dimensions length is 14 cm and breadth is  9 cm.

Thus the area of the polygon is the sum of areas of rectangle ABCD and DEFG.

The formula of area of rectangle, [tex]A =( length)(breadth)[/tex]

Then total area of the shape is

⇒ [tex](27)(10)+(14)(9)[/tex]

⇒ [tex]270+126[/tex]

⇒ [tex]396[/tex]

Hence we can conclude that the area of the shape is 396 square cm.

Answer:

Q = P - n(x/100)

Step-by-step explanation:

P is the total number of lace edging, n is the number of times the length x is cut from P, and Q is the remnant of the reduction.

So the number of x length is subtracted from P and must be converted to meters (since it is in centimeters) to get Q. That is;

Q = P - n(x/100)
