I might be bad at explaining or even wrong, but i tried. so here it goes.
2 is subtracted from a number (we'll put N for the missing number) and the difference is divided by 3. so i thought the difference was the final answer so i divided 30 by 3.
my equation came out to 2-n=30/3
so from there i did basic algebra.
i added the N to both sides so i came up with 2=30/3+N (so i wouldn't have a negative variable) and the divided 30/3 so then i had 2=90+N.
still with me? i hope so...
so then i subtracted 90 from both sides to get the variable alone and ended with -88=N.
so if you put N in you get 2-(-88)=30/3
you subtract 2 from -88 and get 90. so now you have 90/3 with equals 30.

jolli1 [7]

Answer:

\frac{3}{20}

Step-by-step explanation:

Let x be the cover page

We are given that a newspaper 's cover page is \frac{3}{8} text and photograph fill the rest.

We have to find that how much part of cover's page is the article about endangered species

Text =\frac{3}{8}x

Remaining part =x-\frac{3}{8} x

Remaining part =\frac{8x-3x}{8}=\frac{5}{8} x

Therefore, a newspaper;s cover page fill with  Photograph =\frac{5}{8}

If the article about endangered species=\frac{2}{5} of text

Therefore, the article about endangered species=\frac{2}{5}\times\frac{3x}{8}=\frac{3}{20}x

Hence,  the article about endangered species is \frac{3}{20}of the cover page.

John wants to send a letter to Peter, who lives on Tesla
blondinia [14]

Answer:

The minimum number of letters John has to send to be sure that Peter receives his letter is 127 letters

Step-by-step explanation:

The four digit numbers that are multiples of 5 and 7 with the last digit = 0 is found as follows  

Since the last digit of the house number = 10, then the house number is divisible by 10 which also meets the condition that the house number is divisible by 5

We have the four digit numbers from 1000 to 9999

Hence the numbers divisible by both 7 and 10 are from (1000/70 (Which is 14 + 2/7) - 2/7)×70 + 70 = 1050 to (9999/70 (Which is 142 + 59/70)- 59/70)×70= 9940

Which gives 142 - 15 =  127 numbers which are four digit number multiples of 5 and 7 with the last digit = 0

Hence the minimum number of letters John has to send to be sure that Peter receives his letter = 127 letters.
