Answer:

Jenny has 4 pencils.

Step-by-step explanation:

Let

Jenny has pencils = x

Arthur has pencils = 5x+6 (Arthur has 6 more than 5 times the number of pencils as Jenny. )

Total pencils = 30

We need to find how many pencils does Jenny have.

We basically can write the equation:

Total pencils = Jenny pencils + Arthur pencils

Putting values and solving to find value of x:

30=x+5x+6\\30=6x+6\\30-6=6x\\24=6x\\=> 6x=24\\x=\frac{24}{6}\\x=4

So, we have value of x = 4

Now, finding number of Jenny pencils:

Jenny has pencils = x = 4

Therefore, Jenny has 4 pencils.

tony scored 22 and 25 points in the first two games of a basketball tournament. Tony's goal is to make the all-tournament team.
ad-work [718]
Tony's current scores are 22  and 25.
Let x = Tony's next score.

To make the lower required score of 27,
(x + 22 + 25)/3 = 27
x  = 81 - 47 = 34

To make the upper required score of 32,
(x + 22 + 25)/3 = 32
x = 96 - 47 = 49

Answer:
Tony should score between 34 and 49

Ganezh [65]

Answer:

Option C. His answer is not correct, because the same can not be less than either attend

Step-by-step explanation:

we have

\frac{12}{15}+\frac{1}{10} =\frac{13}{25}

we know that

\frac{12}{15}=0.8

\frac{1}{10}=0.10

\frac{13}{25}=0.52

substitute

0.80+0.10=0.52 ----> is not true

therefore

His answer is not correct, because the same can not be less than either attend

Given the graph below, which of the following statements is true?
nirvana33 [79]

Answer:

D) The graph does not represent a one-to-one function because the y-values between 0 to 2 are paired with multiple x-values.

Step-by-step explanation:

Let's find the ordered pairs.

(-4, 4), (-3, 2), (-2, 0), (-1, 0.5), (0, 1), (1, 1.5), (2, 2), (3, 0)

The graph passed through above points.

In the x-coordinates -3, 2 gives the same output. Therefore, the given function is not one-to-one.

Therefore, the answer D)

The graph does not represent a one-to-one function because the y-values between 0 to 2 are paired with multiple x-values.

Hope you will understand the concept.

Thank you.
