<h3>Further explanation</h3>

<u>The Problem:</u>

  • Subtract 4 from \frac{1}{6} of 42.
  • Write an expression to match and then evaluate.

<u>The Process:</u>

Here are some early expressions that need attention.  

  • 1 sixth is \boxed{\frac{1}{6}}
  • 1 sixth of 42 is \boxed{\frac{1}{6} \times 42} or \boxed{\frac{1}{6}} multiply 42.

Let us write an expression to match for subtract 4 from \frac{1}{6} of 42.

\boxed{\boxed{ \ \bigg(\frac{1}{6} \times 42 \bigg) - 4 \ }}

And now we evaluate the expression.

\boxed{ \ = \bigg(\frac{1}{6} \times 42 \bigg) - 4 \ }

We cross out 6 and 42 because they both can be divided.

\boxed{ \ = 7 - 4 \ }

Thus the answer is \boxed{\boxed{ \ 3 \ }}

<u>Notes:</u>

  • Recall that \boxed{\frac{42}{6} \rightarrow 42 \div 6 = 7}
  • Since \boxed{ \ \boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7} = 42 \ }, then one of six parts of 42 or \boxed{\frac{1}{6} \ of \ 42 \ equal \ to \ 7}
  • Since \boxed{1}\boxed{1}\boxed{1}\boxed{1}\boxed{1}\boxed{1}\boxed{1} = 7, then subtract 4 from 7 equal to 3, that is \boxed{1}\boxed{1}\boxed{1} = 3.

a box of marbles can be shared equally among 6,7,or 8 students with 4 marbles left over each time.what is the least possible num
Vlad1618 [11]
If there are 4 marbles left over each time, then we can forget about them for now.

So the question is, what is the smallest number than can be divided into 6,7 and 8?

the numbers have only one non-1 divisor in common: both 6 and 8 are divisible by 3.

so for our purposes we can "delete" one 2 and ask:


what is the smallest number than can be divided into 3,7 and 8 ?

There are no more divisors in common, so we just have to multiply them: 3*7*8=21*8=168


and the 4 marbles "extra"? We add them to this sum.


the the smallest possible number in the box is 168+4=172.

If there are x teams in a sports​ league, and all the teams play each other​ twice, a total of​ N(x) games are​ played, where ​N
Elena-2011 [213]

Answer:

It will cost $700 to play the entire​ schedule.

Step-by-step explanation:

Given : N(x)=x^2-x

To Find :  A softball league has 5 ​teams, each of which play the others twice. If the league pays ​$35 per​ game, how much will it cost to play the entire​ schedule?

Solution:

Equation for total no. of games when all the teams play each other​ twice is N(x)=x^2-x

Now we are given that A softball league has 5 ​teams, each of which play the others twice.

So, Substitute x = 5 in the given equation

N(x)=5^2-5

N(x)=20

So, The total no. of games = 20

Cost for 1 game = $35

So, cost for 20 games = 35 \times 20 = 700

Hence  it will cost $700 to play the entire​ schedule.

According to the synthetic division below, which of the following statements are true?
kykrilka [37]

Answer:

Options (A) and (D)

Step-by-step explanation:

We can write the given division as,

\frac{2x^2+6x-8}{x+5}=2x-4+\frac{12}{x+5}

Option (A)

When (2x² + 6x - 8) is divided (x + 5), the remainder is 12.

True.

Option (B)

When (2x² + 6x - 8) is divided (x - 5), the remainder is 12.

False.

Option (C)

When x = 5,

2x² + 6x - 8 = 12

2(5)² + 6(5) - 8 = 50 + 30 - 8

                        = 72

False.

Option (D)

When x = -5,

2(-5)² + 6(-5) - 8 = 50 - 30 - 8

                          = 12

True.

Option (E)

(x - 5) is a factor of 2x² + 6x - 8

If (x - 5) is a factor value of 2x² + 6x - 8 should be zero.

False.

Option (F)

(x + 5) is a factor of 2x² + 6x - 8

If (x + 5) is a factor then by substituting x = -5 in the expression value should be zero.

But the value is 12.

False.
