together, tom and max have 72 football cards, tom has 2 more than 4 times as many cards as max has, how many football cards does
andrew11 [14]

Answer:

58

Step-by-step explanation:

Let t and m represent the numbers of cards had by Tom and Max, respectively. Then the problem statement tells us ...

  • t + m = 72
  • 4m +2 = t

We want to solve for t. If we multiply the first equation by 4 and subtract the second, we get ...

... 4(t +m) -(4m +2) = 4(72) -(t)

... 4t +4m -4m -2 = 288 -t . . . . . . . eliminate parentheses

... 5t = 290 . . . . . . . . . . . . . . . . . . . add t+2, collect terms

... t = 58 . . . . . . . . divide by the coefficient of t

_____

<em>Alternate Solution</em>

You can work this in your head if you realize that subtacting 2 from the total means that Max has 1/5 of the new amount. 1/5 of 70 is 14, so Tom has 72 - 14 = 58 cards.

The equation yˆ=−5.131x 2+31.821x−3.333 approximates the number of people standing in line to catch a commuter train x hours aft
ololo11 [35]
For this case we have the following equation:
 y = -5.131x ^ 2 + 31.821x - 3.333&#10;
 When it's 5 a.m. then x = 0
 Therefore, when it is 7 a.m. then x = 2.
 Substituting x = 2 in the equation we have:
 y = -5.131 * (2) ^ 2 + 31.821 * (2) - 3.333&#10;&#10;y = 39,785
 Rounding to the nearest whole number:
 y = 40&#10;
 Answer:
 
the best estimate for the number of people in line at 7 a.m. is:
 
y = 40

The given number is 8.234 E14

We need to write this number in standard form.

Any no is given in the standard form is given by :

N=a\times 10^b

Where

a and b is real no and integer

It means,

8.234 E14=8.234 \times 10^{14}

Hence, this is the required solution.
