Step-by-step explanation:

Move all terms that dont  contain x to the right side to solve    

Step-by-step explanation:

5miles=8km

so, x miles=32km

8x=160

x= 160÷8

=20miles

Answer:

.................

Answer:

x=-8

Step-by-step explanation:

2x−3=5x+20+1

2x−3=5x+21

2x−3+3=5x+21+3

Then simplify those numbers

2x=5x+24

Then subtract 5x from both sides

Answer:

x=-8

Step-by-step explanation:

open brackets first

2x - 3 = 5x + 20 + 1

2x - 3 = 5x + 21

transpose

2x - 5x = 21+ 3

calculate

-3x = 24

x= -3/24

x= -8

Answer:

To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.

Step-by-step explanation:

Answer:

it depends, I can't see which angle for some reason, but a triangle has a total of 180 degrees

Answer:

(n - 5)(n + 5)

Step-by-step explanation:

a² - b² = (a - b)(a + b)

n² - 25 = n² - 5² = (n - 5)(n + 5)

Answer:

The force the player hit the ball with is 900 N

Step-by-step explanation:

Given;

mass of the baseball, m = 0.75 kg

acceleration of the ball, a = 1200 m/s²

The force the player hit the ball with is given by the following equations;

F = ma (based on Newton's second law of motion)

where;

F is the applied force

m is mass of the baseball

a is the acceleration of the baseball

F = ma

F = (0.75 x 1200)

F = 900 N

Therefore, the force the player hit the ball with is 900 N

Answer:

The expression x^3 + ax^2 - 15x + b has a factor of x – 2 and leaves a remainder 75 when divided

by x + 3. Find the value of a and of b.

Let p(x) = x3 + ax2 + bx +6

 (x-2) is a factor of the polynomial x3 + ax2 + b x +6

p(2) = 0                                                                                       

p(2) = 23 + a.22 + b.2 +6 =8+4a+2b+6 =14+ 4a+ 2b = 0

7 +2 a +b = 0

b = - 7 -2a -(i)                                                                              

x3 + ax2 + bx +6 when divided by (x-3) leaves remainder 3.

p(3) = 3                                                                                      

p(3) = 33 + a.32 + b.3 +6= 27+9a +3b +6 =33+9a+3b = 3

11+3a +b =1 => 3a+b =-10 => b= -10-3a -(ii)                                    

Equating the value of b from (ii) and (i) , we have

 (- 7 -2a) = (-10 - 3a)

a = -3                                                    

Substituting a = -3 in (i), we get

b = - 7 -2(-3) = -7 + 6 = -1

Thus the values of a and b are -3 and -1 respectively.

Responder:

Número total de bolas = 245/23

Explicación paso a paso:

Dado que:

Bolas blancas = 1/5

Bolas negras = 1/7

Bolas rojas = 7

Sea el número total de bolas = x

Bolas blancas = 1 / 5x

Bolas negras = 1 / 7x

Por tanto, total;

(x / 5 + x / 7 + 7) = x

((7x + 5x) / 35) +7 = x

(12x / 35) + 7 = x

7 = x - 12x / 35

7 = (35x - 12x) / 35

7 = 23 veces / 35

245 = 23x

x = 245/23

Answer:

2 hours

Step-by-step explanation:

Downers grove = 5 inches of snow + 6 inches every hour

= 5 + 6h

Woodridge = 13 inches + 2 inches every hour

= 13 + 2h

Where,

h = number of hours

In how many hours will the snowfall of the towns be equal?

Equate the snow falls of the towns

Downers grove = Woodridge

5 + 6h = 13 + 2h

Collect like terms

5 - 13 = 2h - 6h

8 = 4h

Divide both sides by 4

h = 8 / 4

= 2

h = 2 hours

The snowfall of the towns will be equal in 2 hours
