2(x - 5) = 9 -3x + 6 + 8 + 3x + 7 X=?

Express the recurring decimal 0.142 recurring as a fraction in its simplest form.

kupik [55]

Answer:

7/165

Step-by-step explanation:

We take number after the decimal point 042

then we subtract the non repeating.In this case is 0 so we not subtract anything

This will be the numerator 42

For each repeating decimal we write a 9 (in this case 2 nines)

For each non repeating decimal we write a zero

Denominator is 990

42/990 = 7/165

7:165 = 0.0424242

I think this is what you do. Hope it helps!

Inga [223]

Answer:

The system of inequalities that models the situation is

$x+y \leq 30$

$x(2.50) +y(2.75) \geq 44$

Step-by-step explanation:

Given:

Total number of banana bread and nut bread must be atmost 30

Cost of one banana bread = $2.50

Cost of one nut bread = $2.75

Kona wants to make at least $44

To Find:

The system of inequalities models the situation

Solution:

Let the number of banana bread loaves be x

Let the number of nut bread loaves be y

Then kona wants to make at most 3 loaves of bread,

So

$x+y \leq 30$ -----------------(1)

Then By selling one banana braed to $2.50, and each loaf of nut bread sells for $2.75,Kona wants to make at least $44.

$x(2.50) +y(2.75) \geq 44$ ---------------------(2)

on a large college campus, 84% of the students report drinking alcohol within the past month, 33% report using some type of toba

Natasha_Volkova [10]

Answer: 0.31

Step-by-step explanation:

Let A denotes the event that the students report drinking alcohol and B denotes the students report using some type of tobacco product .

Given : P(A) =0.84 ; P(B)=0.33 and P(A∪B)=0.86

We know that $P(A\cap B)=P(A)+P(B)-P(A\cup B)$

Then, the probability that the student both drunk alcohol and used tobacco in the past month is given by :-

$P(A\cap B)=0.84+0.33-0.86=0.31$

Hence, the probability that the student both drunk alcohol and used tobacco in the past month = 0.31

How many 1/8-foot pieces of ribbon can be cut from a roll of ribbon that is 2 1/2

jonny [76]

Answer:

A. 20

Step-by-step explanation:

We know that there are 8 eights in a whole, and a whole is equal to the number 1. The number 2 consists of two wholes, and so we multiply 8 by 2.

8 wholes in each 1 × 2 ones = 16 wholes

Now, we know that the number 2 is equal to 16 wholes, so now we need to find how much 1/2 of a whole is worth.

1 whole = 8 eights, so divided by 2, it would be 4 eights for a half of a whole.

So, we add 16 + 4 to get the result of 20.
