a machine made 2 2/6 pencils in 3 3/4 minutes. how many pencils would the machine have made after/minute
erma4kov [3.2K]

<em><u>Question:</u></em>

A machine made 2 2/6 pencils in 3 3/4 minutes. How many pencils would the machine have made after 9 minutes?

<em><u>Answer:</u></em>

\frac{504}{90}\ or\ 5.6 pencils is made after 9 minutes

<em><u>Solution:</u></em>

Given that,

A machine made 2 2/6 pencils in 3 3/4 minutes

Which means,

2\frac{2}{6} = \frac{14}{6}

3\frac{3}{4} = \frac{15}{4}

Let "x" be the number of pencils made in 9 minutes

Therefore,

\frac{14}{6}\ pencils = \frac{15}{4}\ minutes\\\\x\ pencil = 9\ minutes

This forms a proportion and we can solve by cross multiplying

\frac{14}{6} \times 9 = \frac{15}{4} \times x\\\\x = \frac{14}{6} \times 9 \times \frac{4}{15}\\\\x = \frac{504}{90}\\\\x = 5.6

Thus, \frac{504}{90}\ or\ 5.6 pencils is made after 9 minutes

Which expression has a value that is equivalent to 5n+13 when n= -5
maks197457 [2]

Answer:

Option A is correct.

4n + 8 expression which has a value that is equivalent to 5n+13 when n = -5

Step-by-step explanation:

Given the expression: 5n + 13

If n = -5

then, by substituting in given expression we get;

5(-5)+13 = -25+13 = -12

Option A:

4n + 8

Substitute the value of n = -5 we have;

4(-5) + 8 = -20 + 8 = -12

Option B:

2n + 2

then;

2(-5) + 2 = -10 + 2 = -8

Option C :

n^2+13

then;

(-5)^2+13 = 25 + 13 = 38

Option D:

n + 8

then;

-5 + 8 = 3

Therefore, only option A has expression which has a value that is equivalent to 5n+13 when n = -5
