I need help fast I appreciate the help

Answer:

multiply both expressions

(8x - 2)(4)

32x - 8

simplify

32x = 8 4 ( 2 2 2 2 2 2)

-8 = 8 -1

8(4x - 1)

Answer:

Step-by-step explanation:

Find h when v = 20 and r = 3

Putting values in the formula

20 = (3.14)(3)2h

20 = (3.14)(9)h

20 = 28.26h

20/28.26 = h

R when v = 100 and h = 5

100 = (3.14)r2(5)

100/5 = 3.14r2

20 = 3.14r2

20/3.14 = r2

6.36 = r2

Square root on both sides

2.52 = r

Answer:

1=125

2=55

3=55

Answer:

Rs. X + Rs. 10y

Step-by-step explanation:

Charge for 40 km travel = Rs. x per km

Charge for every additional km traveled = Rs. y

Amount paid for 50 km

Fixed charge for 40km = Rs. X

Additional km = 50 - 40 = 10 kilometer

Total charge :

Rs. X + Rs. 10y

Answer:

A) -6+2

Step-by-step explanation:

Answer:

Solution

1 Cancel 77 on both sides

x\times 0.04=x\times 4xx×0.04=x×4x

2 Regroup terms

0.04x=x\times 4x0.04x=x×4x

3 Use Product Rule: {x}^{a}{x}^{b}={x}^{a+b}x

​a

​​ x

​b

​​ =x

​a+b

​​

0.04x={x}^{2}\times 40.04x=x

​2

​​ ×4

4 Regroup terms

0.04x=4{x}^{2}0.04x=4x

​2

​​

5 Move all terms to one side

0.04x-4{x}^{2}=00.04x−4x

​2

​​ =0

6) Factor out the common term x

x(0.04-4x)=0

7 Solve for x

x=0,0.01

Done!

Step-by-step explanation:

Answer:  

Step-by-step explanation:

1/10 + 2.5/10 = 3.5/10 of an hour to make one bracelet. Then change to 20ths so the numerator is a whole number.

Divide your time available by the time it takes to make one.                  

                                               21  

                                               4             = 420= 15 bracelets

                                               7                 28

                                              20

Answer: 11ft

Step-by-step explanation:

Answer:

y = x-4

Step-by-step explanation:

First find the slope

m = ( y2-y1)/(x2-x1)

   = ( -3 -1)/( 1 - 5)

   = -4/-4

   = 1

Then using slope intercept form

y = mx+b where m is the slope and b is the y intercept

y = 1x+b

Substitute one of the points in

1 = 5 +b

1-5 = b

-4 =b

y = x-4

2d+22

Step-by-step explanation:

question isn't clear but I believe you are asking for the area of triangle ABC given sides a, b, c

We use the example question:

Find the area (in square units) of the triangle described.

a = 49mm, b = 33mm, c = 18mm

Answer and explanation:

We apply Heron's formula to solve the area of a triangle given the sides of the triangle a, b, c

A= √s(s-a)(s-b)(s-c)

Where A = area of triangle in square units

s= semiperimeter(a+b+c/2) of a triangle

a, b, c= lengths of the sides of the triangle

Therefore area of triangle =√50(50-49)(50-33)(50-18)

= √27200

=164.92mm²

.

Answer:

$1.10

Step-by-step explanation:

The first two stickers cost $0.8. The thrird one will cost 75% of the cost of one sticker. To find the answer, you multiply 0.75 (0.75 is 75% as a decimal) by 0.4 to get 0.3. $0.3 plus $0.8 equals $1.10.

Answer:

x = 2

y = 12

Step-by-step explanation:

In triangle ABD, CE is the mid segment.

Therefore, by mid segment theorem:

2(5x - 3) = x + 12

10x - 6 = x + 12

10x - x = 12 + 6

9x = 18

x = 18/9

x = 2

Since, DE = EA

2y - 4 = y + 8

2y - y = 8 + 4

y = 12

Answer:

49

Step-by-step explanation:

(−11 2/3)(−4 1/5)

=  (-35/3) (-21/5)

= 49

Answer:

100

Step-by-step explanation:

Isosceles triangle have 2 equal angles. Therefore the second angle in the triangle will also be 25.

Since the sum of angles in a triangle is 180.

180-(25x2) will give you the last angle in one of the triangles.

The other angle is identical so the angle at the top of the other triangle will also be 130.

The sum of angles in a circle is 360.

Therefore, angle x = 360-(130x2)

X= 100

Answer: (x, y)=(0, -6）

Step-by-step explanation:

To solve a system of equations there are usually 3 general ways.

- Elimination

- Substitution

- Augmented Matrix

Since the question is asked to use elimination, we are going to use it.

--------------------------------------------------------------------------------------

-5x+4y=30

2x+3y=-12

-10x+8y=60

10x+15y=-60

23y=0

y=0

------------------------------------------------------------------------------------------

Substitute the y value into any one of the equations

2x+3y=-12

2x+3(0)=-12

2x+0=-12

x=-6

Answer:

5) x=39

Step-by-step explanation:

if you see the triangle it has  two equal sides which mean is an Isosceles Triangle    so if a triangle =180

we can say that   x+x+102=108 if we solve that we got x=39
