amanda, bryan, and colin are in a book club. amanda reads twice as many books as bryan per month and colin reads 4 fewer than 3

lesya [120]

Please see below solution:
Let x = number of books that Bryan reads2x for amanda = Amanda 3x - 4 for Colin Amanda = 5/8(Bryan + Colin)2x = 5/8(x+3x-4)2x = 5/8(4x-4)

[16x = 5(4x-4)]816x = 20x - 20Subtract 20x from each side-4x =-20-4x/-4= -20/-4 divide -4 to eliminate the -4 in -4xx = 5
Therefore:
Bryan reads 5 books a month.
Since Amanda reads twice as many books a Bryan read so Amanda 10 books a month.
And Colin 11 books a month. 3(5) - 4 = 11

The sum of two consecutive even integers is 26. What is the product of the two integers?

lions [1.4K]

(2x) + (2x + 2) = 26
4x + 2 = 26
4x = 24
x = 6

The numbers are 12 and 14

12*14 = 168

What is the reflection of image p(0,0) after two reflections first across x=-3 and

pochemuha

<span>P (0, 0) across x = -3 will change the x value. From 0 to -3 which is 3 units down, so the reflection will be another 3 units down ( points are the same distance from the reflection line) so the new x-value is -6 now just do the same thing for the y-value and you will get an image of P¹ ( -6, -6 ) </span>

a motorboat traveling with a current can go 160km in 4 hours. against the current it takes 5 hours to go the same distance. find

irakobra [83]

The speed of motorboat is 36 kmph and speed of current is 4 kmph.

Step-by-step explanation:

Distance covered in 4 hours = 160 km

Time took on return trip = 5 hours

Let,

x represent the speed of boat.

y represent the speed of current.

Combined speed of boat and current when in same direction = x+y

Speed of boat and current when travelling against = x-y

Distance = Speed * Time

Speed = $\frac{Distance}{Time}$

x+y = $\frac{160}{4}$

x+y = 40 Eqn 1

x-y = $\frac{160}{5}$

x-y = 32 Eqn 2

Adding Eqn 1 and Eqn 2

$(x+y)+(x-y)=40+32\\x+y+x-y=72\\2x=72$

Dividing both sides by 2

$\frac{2x}{2}=\frac{72}{2}\\x=36$

Putting x=36 in Eqn 1

$36+y=40\\y=40-36\\y=4$

The speed of motorboat is 36 kmph and speed of current is 4 kmph.
