Makaila read 44 pages of her book yesterday and 2/3 of the book today. If she read a total of 200 pages in the past two days how
pogonyaev

Answer:

Total number of pages in the book is 234.

Step-by-step explanation:

Let us assume that the total number of pages in the book = <em>x</em>

Now, it is given that Makaila read 44 pages yesterday.

Also, Makaila read two-third of the book today. As we have assumed that, there are a total of x number of pages in the book, so we can say that Makaila read two-third of <em>x </em>number of pages today.

Number of pages read by Makaila today = \frac{2}{3}\;of\;x=\frac{2}{3}\times\;x=\frac{2x}{3}

Now, it is also given that, Makaila read a total of 200 pages in the past two days.

∴ according to question,

Pages read yesterday + Pages read today = 200

⇒44+\frac{22x}{3}=200

⇒\frac{44\times3+2x}{3}=200

⇒\frac{132+2x}{3}=200

⇒132+2x=200\times3\;\;\;\;\;\;\;\;\;[On\;cross-multiplying]

⇒132+2x=600

⇒2x=600-132

⇒2x=468

⇒x=\frac{468}{2}=234

∴ Total number of pages in the book = <em>x</em> = 234

Please give me the answer quick
Vlada [557]

Answer:

MON= 57

Step-by-step explanation:

5x-23+3x-15=90

8x-38=90

8x=128

x=16

PLUG 16 INTO MON EQUATION

5(16)-23=57

therefore,

MON=57

USE COMPLEMENTARY FOR PROBLEMS LIKE THIS :)))

(btw, assuming that the angle is 90 degrees)

How do I do Slope Intercept Form Step to Step? PLEASE HELP!
Arlecino [84]

So if an equation was f(x)=x+4

you would automatically change f(x) into y

so it would y-y=x(x-x)

so you plug in the x and 4 which is the first y and x

y-4=x(x-x)

you switch the numbers around

so your final answer would be x-4
