Answer:

Choice B is the correct answer.

Step-by-step explanation:

We have given an inequality.

|4-7x| -5 < 8

We have to find the solution of given inequality.

Adding 5 to both sides of given inequality, we have

|4-7x| < 8+5

|4-7x| < 13

Applying absolute value rule, we have

-13 < 4-7x < 13

-13-4 < -7x < 13-4

-17 < -7x < 9

By dividing to -7 , reverse the inequality

-9/7 < x < 17/7

Hence, the solutions are x < 17/7 or x > -9/7.

Answer:

b. {x l -9/7 < x <17/7}

Step-by-step explanation:

l 4 - 7xl -5 < 8

Adding 5 on both sides, we get

l4 - 7xl < 13

Absolute function has two values.

{ 4 - 7x < 13 and (4-7x) > -13}

Now let's solve for x.

-7x < 9  and -7x > -17

x > -9/7 and x < 17/7

Now we have to combine the two inequalities and write the solution

{x l -9/7 < x <17/7}

Answer: b. {x l -9/7 < x <17/7}

Hope this will helpful.

Thank you.

irga5000 [103]

Answer:

x=1

Step-by-step explanation:

Its x=1 because if we put the 1 as in x then it will be like 2(1)+3(4(1)-3)= 8-3(1)

2(1)+3(4(1)-3) is equal to 5

8-3(1) is equal to 5

5=5

so x is 1

A person draws a card from a hat. Each card is one color, with the following probabilities of being drawn: 1/10 for white, 1/15
Salsk061 [2.6K]

The probability of pulling a red or green card, written as a reduced fraction is 1/4

<h3>How to determine the probability of pulling a red or green card, written as a reduced fraction?</h3>

From the question, we have the following probabilities:

P(White) = 1/10

P(Pink) = 1/5

P(Green) = 1/20

P(Red) = 1/5

The probability of pulling a red or green card, written as a reduced fraction is the calculated as:

P(Red or Green card) = P(Red card) + P(Green card)

Substitute the known values in the above equation

P(Red or Green card) = 1/5 + 1/20

Express 1/5 as 4/20

P(Red or Green card) = 4/20 + 1/20

Take the LCM

P(Red or Green card) = (4+1)/20

Evaluate the sum

P(Red or Green card) = 5/20

Simplify the fraction

P(Red or Green card) = 1/4

Hence, the probability of pulling a red or green card, written as a reduced fraction is 1/4

1 5 y + 8 − 4 5 = 9 10 y − 9 20
emmainna [20.7K]

Answer:

y ≈  .98   i hope this helps :)

Step-by-step explanation:

given equation   15y + 8 - 45 = 910y - 920

simplify the equation   15y - 37 = 910y - 920

subtract 15y from both sides   -37 = 895y - 920

add 920 to both sides   883 = 895y

divide both sides by 895   .98 ≈ y

y ≈  .98
