The decimal equivalent of 3/7 rounded to the nearest hundredth is _____.
astra-53 [7]
3/7 = 0.4285714286.
The hundredth place is 2 places to the right of the decimal. In this case, it is 2. So we look to the number to the right of 2 (which is 8). 8 ≥ 5, so the 2 gets rounded to a 3.

3x+1/10=x-1/7 what is x explain how you got the answer please do a step by step solution
polet [3.4K]
Ok, to solve an algebraic equation we need to get the unknown by itself on one side of the equals sign.  To do that, basically we just have to cancel everything else out... but whatever we do to cancel out what we don't want, we also have to do on the other side of the equals sign...

3x + 1/10 = x - 1/7

Let's start by getting the x on the right over to the left side.  To cancel it from the right side we have to subtract it (x-x = 0).  Don't forget to subtract it on the left also.

3x -x + 1/10 = x - x - 1/7

Now combine like terms

2x + 1/10 = -1/7

Now let's bring the 1/10 over to the right of the equals sign to get x by itself by subtracting it.

2x + 1/10 - 1/10 = -1/7 - 1/10
 
Combine like terms

2x = -1/7 - 1/10

Let's get a common denominator so we can combine the fractions

2x = -10/70 - 7/70
2x = -17/70

Now divide both sides by 2 to finish getting x by itself.  To divide fractions, multiply the reciprocal.

x = -17/70 x 1/2
x = -17/140

Mr. Akika has 30 24-cent and 33-cent stamps all told. The stamps are worth $8.91. How many of each kind of stamp does he have?
riadik2000 [5.3K]

Answer:

  • 24-cent: 11
  • 33-cent: 19

Step-by-step explanation:

I find it easiest to solve these using the variable to represent the number of the most-expensive item. Let x represent the number of 33-cent stamps. Then the total value (in cents) is ...

  33x +24(30 -x) = 891

  9x = 171 . . . . . . . . . . . . . subtract 24(30), collect terms

  x = 19 . . . . . . . . . . . . divide by 9

  30-x = 11 . . . . . . . find the number of 24-cent stamps

Mr. Akika had 11 24-cent stamps and 19 33-cent stamps.

_____

<em>Additional comment</em>

You seem to have several of these to solve. They all have a similar solution.

If we let x represent the number of higher-value items, N, the total number of items, V the total value, and v1 and v2 the individual values (v2 > v1), the equation is ...

  v2(x) +v1(N -x) = V

  x(v2 -v1) = V -v1·N

  x = (V -v1·N)/(v2 -v1) . . . . generic solution

Using this formula in the problem here, we find ...

  x = (891 -24(30))/(33 -24) = 171/9 = 19 . . . as above
