Answer:

  • 7 people
  • 53 coins

Step-by-step explanation:

The problem statement tells us ...

  8x = y +3

  7x = y -4

Subtracting the second equation from the first gives ...

  x = 7

Then ...

  y = 7x +4 = 7·7 +4 = 53

There are 7 people, and 53 coins are required for purchase.

Simplify 5m-2(6m-5)+2<br><br>a. -7m-8<br>b. -7m+12<br>c. 17m+12<br>d. 17m-8
fgiga [73]

The answer is B. -7m+12.


First distribute the -2 to 6m and -5.

5m-2(6m-5)+2

5m+(-2*6m)+(-2*-5)+2

5m+-12m+10+2


After that, combine the like terms.

5m+-12m+10+2

-5m+-12m=-7m

10+2=12


The simplified expression is -7m+12.

Joe has four notes in his wallet. The total value of the notes is $75. Which type of note is not in Joe's wallet?
Sergio039 [100]

Answer:

$ 20

Step-by-step explanation:

Given that,

No. of notes Joe has = 4

The total value of the notes = $ 75

From the given notes, 4 notes that can make the sum of 75 would be

$ 50 note + $ 10 + $ 10 note + $ 5

= 50 * 1 + 10 * 1 + 10 * 1 + 5 * 1

= $ 75  

Thus, the note that would not be included in the total value would $20 note as if we add it either the sum would be greater or lesser with four notes in combination.
