Solving Inequalities
2n + 7 > 27 or 3 + 3n < 30
Not sure how to solve this, if I could get the steps, that would be great

Answers

Answer 1

Answer:

n > 10

n < 9

Interval notation:

(-∞, 9) U (10, ∞)

Step-by-step explanation:

2n + 7 > 27 or 3 + 3n < 30

     -7     -7      -3             -3

2n > 20                 3n < 27

÷2    ÷2                ÷3     ÷3

n > 10                      n < 9

<---------            ----------->

<---------0--------0--------->

           9         10

I hope this helps!

Answer 2
n > 10 and n > 9


Explanation:

1. 2n+7 > 27. Subtract 7 from both sides to get 2n > 20. Divide both sides by 2 to get n > 10.

2. 3+3n > 30. Subtract 3 from both sides to get 3n > 27. Divide both sides by 3 to get n > 9.

I hope this helps! :)

What will be the actual dimensions of Laurie’s garden?

Answers

The dimensions in ft will go from 8cm by 4cm to, 21.25ft by 10

1/2 is 0.5 as a decimal. So 8.5 multiplied by 2.5 is 21.25, 4 multiplied by 2.5 is 10.

Answer:

The length is 10 and the width is 21.25

Step-by-step explanation:

You time 2.5 × 4 = 10 to get the width

You time 2.5 × 8 = 20 and 1 half of 2.5 is 1.25.

So you add 20 + 1.25 = 21.25 and that is your width.

So the answer is length is 10 and width is 21.25

Which expression is equivalent to −4(b − 8)?

Ill give brainliest answer
Fast please have 1 minute

Answers

Answer:

Step-by-step explanation: We are given relation between distance (in kilometers) travelled and number of hours taken by an Albatross bird.

Distance in kilometers taken by variable d.

Number of hours by t.

And situation is given d=50t.

We know, direct relation formula y= kx read as y is directly proportional to x. And k is the constants of proportionality.

In the given fuction y is taken by variable d and x is taken by variable t.

If we compare d=50t by y = mx, the value of k is 50.

Therefore, constant of proportionality is 50.

Constant is a number that never change it's value.

Therefore, constant of proportionality is just 50.

But we can say variables d and t are two variables those are directly proportional to each other.

Constant of proportionality is actually unit rate of change.

For the given situation constant of proportionality is the number of km travelled in per unit time (in 1 hour.)

If we divide 400km 8 hours, we get 400/8 = 50 km per hour.

Therefore, variables of proporation are d and t and relation between them is " they are directly proportional to each other".

And the constants of proportionality is just 50.

Question: t - 12/2 = 3t/2 -3


Answers:

t = -3
t = -1
t = 1
t = 3

Answers

Answer:

t = -3

Step-by-step explanation:

move t/2 right, we have 3*t/2 - t/2 = t

move subtract 3 left, we have -6 + 3 = -3

then t = -3

Answer:

t=−6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

t - 12/2 = 3t/2 - 3

t + -6 = 3/2t + -3

t - 6 = 3/2t - 3

Step 2: Subtract 3/2t from both sides.

t − 6 − 3/2t = 3/2t - 3 - 3/2t

-1/2t - 6 = -3

Step 3: Add 6 to both sides.

-1/2t - 6 + 6 = -3 + 6

-1/2t = 3

Step 4: Multiply both sides by 2/(-1).

(2/-1) x (-1/2t) = 2/-1 x 3

t = -6

What is the value of −5 + |−18|?

A} 13

Answers

Absolute value makes the number positive, so now you have -5+18, then adding a negative to a positive is the same as subtracting. Therefore, 18-5=13. Answer should be A}
-5 + 18 = 13 A because the absolute value cancels out the negative on the 18 meaning you could just take away 5 from 18 leaving you with 13

Which expression is equivalent to 4(2.61y − 3.08)?

A - 10.44y + 3.08
B - 10.44y − 3.08
C - 10.44y + 12.32
D - 10.44y − 12.32

Answers

Answer: B

I am like 99% sure this is correct if not let me know

The equivalent expression is indeed 10.44y - 12.32 (option d).

let's break down the process of distributing the 4 to both terms inside the parentheses step by step:

Given expression: 4(2.61y - 3.08)

Distribute the 4 to both terms inside the parentheses:

4 * 2.61y - 4 * 3.08

Multiply 4 by 2.61y:

10.44y

Multiply 4 by 3.08:

-12.32

Now, putting it all together, the distributed expression becomes:

10.44y - 12.32

Therefore, after distributing the 4 to both terms inside the parentheses, the equivalent expression is indeed 10.44y - 12.32. This matches option D - "10.44y - 12.32".

Step-by-step explanation:

in order to solve this problem you would have to essentially just use the formula which is A= length times width

in this case you would have to multiply 4 by 8 1/2 in order to get 8 1/2 into a fraction to make it easier to multiply you would multiply 8 by 2 and add 1 so your fraction would be 16/2. So the denominator 2 cancels with 4 giving you 2 times 17 and that would be 34
