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

B

Step-by-step explanation:

The answer should be B

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

Answer is from/credits= WaywardDelaney

The distance cover by Noah in 1 hour to cover distance is 6.5 miles

Step-by-step explanation:

Given as :

The distance cover by Lin = 2 miles = miles

The time taken to cover distance by Lin = hours

Again

The distance cover by Noah = 8 miles = miles

The time taken to cover distance by Noah = hours

Let the distance cover by Noah in 1 hour = d miles

∵ The distance cover by Noah in hours = miles

∴ The distance cover by Noah in 1 hour =

I.e d = miles

or, d = = 6.5 miles

So, The distance cover by Noah in 1 hour = d = 6.5 miles

Hence, The distance cover by Noah in 1 hour to cover distance is 6.5 miles Answer

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:

900

Answer:

[tex]Fraction = \frac{1}{4}[/tex]

Step-by-step explanation:

Given

[tex]Pie = \frac{3}{4}[/tex]

[tex]Workers = 3[/tex]

Required

Determine the fraction received by each worker

To do this, we simply divide the fraction of the pie by the number of workers.

[tex]Fraction = \frac{Pie}{Workers}[/tex]

[tex]Fraction = \frac{3}{4}/3[/tex]

Convert to multiplication

[tex]Fraction = \frac{3}{4} * \frac{1}{3}[/tex]

[tex]Fraction = \frac{3}{12}[/tex]

Divide numerator and denominator by 3

[tex]Fraction = \frac{3/3}{12/3}[/tex]

[tex]Fraction = \frac{1}{4}[/tex]

Answer

the slope is 1

Step-by-step explanation:

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.
