Math can anyone help me

Answer:

r = -11

Step-by-step explanation:

14-r ÷ [2-(-3)] = 5

cross-multiply:

14-r = 5*5

14-r = 25

-r = 11

r = -11

Hope it helps you,

Step-by-step explanation:

As the figure can be split in to 3 geometric figure,

Rectangle , Triangle and Semi circle ,

So first find the area of these figures then add up them ,

Area of rectangle = Length * width

Length = 20m m  and  width  = 14 mm

hence

Area of rectangle = 20*14  = 280 mm^2

Now ,

Are of  Circle  =  [tex]\\ \pi *d^{2} /4[/tex]

Then Area of semi circle = [tex]\\ \pi *d^{2} /8[/tex]

Hence we have d= 20mm

Putt in semi circle formula we get,

Area of Semi Circle= (3.14)*400/8  = 157 mm^2

Now area of triangle = 1/2 * length*width

length =32-20 = 12 mm

width = 14 mm

putt in the formula we get ,

Area of triangle = 1/2*12*14 = 84 mm^2

Now add these 3 Areas to get total Area,

Answer:

Explanation:

2(6 - x) = 3

2(6 - x) = 3

12 - 2x = 3

12 - 2x - 12 = 3 - 12

-2x = -9

-2x / -2 = -9 / -2

Answer:

C) Adjacent angles

Step-by-step explanation:

Adjacent angles are two angles that have a common vertex and a common side but do not overlap

also complementary is 90 degree so No

Vertical are opposite so No

Corresponding are on parallel lines so No

Answer:

Isosceles Triangle

Step-by-step explanation:

It has 2 equal degree's which are 74 and one 14 degree which makes it an isosceles triangle.

Answer:

an acute isosceles

Step-by-step explanation:

all of the angles are less than 90 and two of the side lengths are going to be the same length because to of the angles are the same

Range: 12, 13, 14, 15

Answer:

5/4

Step-by-step explanation:

Rise over run you go up 5 and left 4 so 5/4 is the ROC.

The rate of change of the function is given by the slope of the line m = -4/3

The equation of a line is y = mx + b where m is the slope which is the rise by run and b is the y-intercept

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

Given data ,

Let the rate of change of the function be m

The equation is represented as A

Now , the value of A is

Let the first point be P ( 0 , 4 )

Let the second point be Q ( 3 , 0 )

Slope m = -4/3

On simplifying the equation , we get

Slope m = -4/3

Now , the equation of line is

y - 4 = ( -4/3 ) ( x - 0 )

On simplifying the equation , we egt

y - 4 = ( -4/3 )x

y = ( -4/3 )x + 4

Hence , the equation of line is y = ( -4/3 )x + 4 and the rate of change of the function is m = -4/3

Answer:

n=3

Step-by-step explanation:

5n+3=18

subtract 3 from both sides

5n=15

divide by 5 on both sides

n=3

Answer:

n=3

Step-by-step explanation:

step 1- subtract 3 to both sides

+3-3=0    18-3=15

5n=15

step 2- divide both sides by 5

5÷5=1       15÷5=3

step 3- check answer by plugging in for n

5(3)+3=18

15+3=18

18=18
