Step-by-step explanation:

  • x/(2x - 4) - (2x - 11)/(x + 2) = 5/8
  • x/(x - 2) - (4x - 22)/(x + 2) = 5/4
  • x(x + 2) - (4x - 22)(x - 2) = 5/4(x + 2)(x - 2)
  • 4(x² + 2x - 4x² + 8x + 22x - 44) = 5(x² - 4)
  • 4(-3x² + 32x - 44) = 5x² - 20
  • - 12x² + 128x - 176 - 5x² + 20 = 0
  • - 17x² + 128x - 156 = 0
  • 17x² - 128x + 156 = 0
  • x = (64 ± 38)/17
  • x = 6 or x = 26/17

A summer camp has 32 campers. 22 of them swim, 20 play softball, and 5 do not play softball or swim. which values correctly comp
Lapatulllka [165]

The values which completes the table regarding summer camp is option b which is a=15,b=7, c=5, d=10, e=12.

Given that there are 32 campers, 22 of them can swim, 20 play softball and 5 do not play softball or swim.

We have to find the values of a,b,c,d,e so that we can complete the table.

Table is a combination of rows and columns. In our case the third row and third column shows the total.

from the table we can write that 22+d=32-----------1

so d=32-22

=10

d=10

c+5=d-----------2

c=10-5=5

c=5

a+c=20------------------3

a+5=20

a=20-5

a=15

a+b=22--------------3

15+b=22

b=7

20+e=32----------4

e=32-22

e=10.

Hence the values which completes the table is a=15,b=7, c=5, d=10,  e=12.

City A grows by 5% every year. In 2021, it has a population of 145,201. What will the population be in 2037?
Diano4ka-milaya [45]

Answer:

About 316,955 people

Step-by-step explanation:

The population of this city can be modeled with the formula P=I\cdot(1.05^t), where P represents the current population, I represents the initial population, and t represents the amount of time in years since the start of the model. Plugging in 145,201 for I and (2037-2021)=16 for t, we get:

P=145201\cdot(1.05)^{16}\approx145201\cdot2.18\approx 316955

A private jet flies the same distance in 8 hours that a commercial jet flies in 7 hours. If the speed of the commercial jet was
mamaluj [8]

Solving a system of equations, we can see that:

  • Speed of the private jet: 168 mi/h
  • Speed of the commercial jet: 192mi/h

<h3>How to find the speeds of each jet?</h3>

Let's define the variables:

  • P = speed of the private jet.
  • C = speed of the commercial jet.

With the given information, we can write:

P*8h = D

C*7h = D

C = 2*P - 144mi/h

So we have a system of 3 equations, where D is the distance in the problem.

With the first and second equations we can write:

P*8h = D = C*7h

Isolating P, we get:

P = C*(7/8)

Now we can replace that in the last equation:

C = 2*P - 144mi/h

C = 2*C*(7/8) - 144mi/h

And now we can solve that for C.

C - 2*(7/8)*C = - 144mi/h

C*(1 - 14/8) = -144mi/h

C*(8/8 - 14/8) = - 144mi/h

C*(6/8) = 144mi/h

C = (8/6)*144mi/h = 192mi/h

Now that we know the speed of the commercial jet, we can find the speed of the private jet.

P = C*(7/8) = 192mi/h*(7/8) = 168 mi/h
