c. -2x - 2 < 8

d. 10x - 100 > 0

**Answer:**

[tex]3x - 3 > 6\\= 3x - 3\\=0x\\0x < 6\\\\24x + 4 = 28x\\28x < 52\\\\-2x - 2 < 8\\= -2x - 2\\= -4x\\-4x < 8\\\\10x - 100 > 0\\= 10x - 100 \\=-90x\\-90x > 0[/tex]<---- Why is -90x greater than 0?

because 90x > 0.

**Step-by-step explanation:**

hope this helped.

**Answer:**

a. = x > 3

b. = x < 2

c. = x > -5

d. = x > 10

**Step-by-step explanation:**

**Solve ****means to find x.**** **

a.

3x - 3 > 6

+3 each side

3x > 9

Divide by 3 each side

x > 3

b.

24x + 4 < 52

-4 each side

24x < 48

Divide by 24 each side

x < 2

c.

-2x - 2 < 8

+2 each side

-2x < 10

Divide by -2 each side (Causing the inequality sign to flip, dividing or multiplying by a negative causes it to.)

x > -5

d.

10x - 100 > 0

+100 each side

10x > 100

Divide by 10 each side

x > 10

Question: 5/12 − 2/5= 1/60

A. The answer 1/60 is not reasonable because 5/12 is closer to 1 than to 1/2, and 2/5 is closer to 0 than to 1/2, making the difference close to 1/2.

B. The answer 1/60 is not reasonable because 5/12 is closer to 1/2 than to 1, and 2/5 is closer to 0 than to 1/2, making the difference close to 1/2.

C. The answer 1/60 is reasonable because both fractions are closer to 1/2 than they are to 0, making the difference close to 0.

D. The answer 1/60 is reasonable because both fractions are closer to 1 than they are to 1/2, making the difference close to 0.

**Answer:**

C

**Step-by-step explanation:**

**It is reasonable**: the answer is both reasonable and correct because 5/12 - 2/5 = 1/60. This is because using cross multiply, 5 x 5/12 = 25/60, 12 x 2/5 = 24/60. 25/60 - 24/60 = 1/60.

**Both are closer to half: **half out of 12 would be 6/12 and 0 would be 0/12, so 5/12 is closer to half because 5/12 is closer to 6/12 than 0/12. Half out of 5 would be 2.5/5 and 0 would be 0/5, so 2/5 is closer to half because 2/5 is closer to 2.5/5 than 0/5.

**The difference is close to 0: **1/60 is very close to 0. It's only worth 0.016.

Sarah babysits her neighbor's son to make money. Her earnings can be represented by the equation

M = 9h

where M is the money she earns and h is the hours she babysits.

Samara babysits her cousin to make money. Her earnings can be represented by the graph.

Which babysitter earns more money per hour?

**Answer:**

Sarah makes more money.

**Step-by-step explanation:**

Sarah makes $9 an hour babysitting while Samara make $3 an hour babysitting. For every 1-hour Sara babysits, Samara has to babysit 3-hours to make the same amount of money. Hope this helps :)

Sarah makes more money

Your friend finds the value of 8⁴. 8⁴ = 8x4 = 32 Is your friend correct? Explain

I would say my friend is correct. I think this because when doing function tables, i would often say x2, x5, etc. This would mean that it would be X x 2, and X x 5. If you replace the "x" and turn it into 8, than I would think it would mean the same thing. So, yes. My friend is correct.

I'm not sure if this was what you were looking for, but I hope this helps somehow!

Sally has 243.75 pieces of candy. John has 27.4 pieces of candy. How many pieces of candy do they have in all? John thinks altogether there are 217.15 pieces of candy. Is he correct? Explain your thinking.

**Answer:**

Yes, John is correct.

**Step-by-step explanation:**

To find the total amount of candy you must add the amounts Sally and John have. Sally has 243.75 and John has 27.4. When you add those two together you can 217.5 which is what John thinks therefore he is correct.

Ramiro is 3/10 as tall as the flagpole. The flagpole is 5/9 as tall as the nearby tree. The tree is 32 2/5 feet tall. How tall is Ramiro?

**Answer:**

5.4 feet

**Step-by-step explanation:**

Start with the flagpole. It is 5/9 of 32 2/5.

32 2/5 = 162/5.

5/9 * 162/5 = 162/9.

Ramiro is 3/10 as tall as 162/9.

3/10 * 162/9 = 27/5, or 5.4 feet tall

His height is 5.4 f

Sarah wanted to buy a TV. She had $390 in her pocket. The TV she wanted was $415; however she had a 10% off coupon. The sales tax is 6%. Does she have enough money to purchase the TV?

Answer: Sarah does not have enough money to purchase the TV.

Explanation: The total price is $395.91.

**Answer:**

No

**Step-by-step explanation:**

10% of 415

= 1/10 of 415

= 1/10 * 415

= $41.5

415 - 41.5 = $ 373.5

6% of 415

= 6% * 415

= $24.9

∴ $373.5 + $24.9 = $398.4

∴ Sarah cannot buy the TV as she is $ 8.4 short.

**Step-by-step explanation:**

The volume is the base (9x9) times the height (11).

**Answer:**

The answer should be 891m

You multiply the Width, Length, and Height ( 9 x 9 x 11)

which would give you 891m.

What is the solution to this equation?

−6(x+7)=−30

Enter your answer in the box.

**Answer:**

x = -2

**Step-by-step explanation:**

-6(x + 7) = -30

distribute the -6

-6 * x = -6x and -6 * 7 = -42

-6x - 42 = -30

add 42 to both sides

-6x = 12

divide both sides by -6

-6x/-6 = x and 12/-6 = -2

we're left with x = -2

6 x ( 10 + 3 ) - 18 help me please ǝɯᴉʇ ɹnoʎ ɹoɟ noʎ ʞuɐɥʇ .

**Answer:**

The answer is 60

**Step-by-step explanation:**

6 x ( 10 + 3 ) - 18

6 x 13 - 18

78 - 18

60

Answer is 60.

6 • (10 + 3) - 18

6 • 13 - 18 (solve parentheses)

6 • 13 = 78 (multiplication)

78 - 18 = 60 (subtraction)

6 • (10 + 3) - 18

6 • 13 - 18 (solve parentheses)

6 • 13 = 78 (multiplication)

78 - 18 = 60 (subtraction)

Archer Middle School has 78 students playing soccer this year. This number is 6 more than 3 times the number of students who played last year. Let n represent the number of students who played last year. Which equation expresses an equality between two different ways of expressing the number of students who are playing soccer this year?

A: n + 6 = 78

B: 3n + 6 = 78

C: n - 6 = 78

D: 3n - 6 = 78

The answer is B. This is because we know this is 6 more than 3 times the number of students that played last year. A and C makes no sense. D does not make any sense because it is 6 more not 6 less.

b is the answer bc you are adding the 6 and multiplying the 3 with the variable

Giovanni can read 210 words per minute. If there are approximately 540 words on a page, about how many pages can he read in 3 hours? Round your answer to the nearest whole number.

462 pages

122 pages

233 pages

70 pages

It would be 70 pages because 210 divided by 3 is 70

She can read 70 **pages **in 3 hours.

A **proportion **is a fraction of a total amount, and the measures are related using a rule of three.

The relations between **variables**, either direct or inverse proportional, can be built to find the desired measures in the problem.

We are Given:

**Giovanni **can read 210 words per minute and, books contain 540 pages

So, she can read the portion of **book**

=210/540

= 21/54 per minutes

= 21/54 x 60

= 23.3 **pages **in one hour

and in 3 hours she can read

= 23.3 x 3

= 70 pages in 3 **hours**
