6 less than a number is 15. Let x represent the number. Which equation represents this?

1 answer:

4 0

**Note / Protip**
Always substitute "a number" for your variable when reading worded equations!
With that being said...

<span>D. x - 6 = 15

Is your answer, since you are going to want to reverse it because of how the problem's worded, not c. because; c.'s worded equation would be
"A number less than six."

Expand the brackets. 7 ( 5 + g ) 11 ( 3s – 4 ) 4 ( 4 – x ) 8 ( 6 + 4w )

goldfiish [28.3K]

Answer:

See answers below

Step-by-step explanation:

Expand the brackets. 7 ( 5 + g ) 11 ( 3s – 4 ) 4 ( 4 – x ) 8 ( 6 + 4w )

We will expand each of the bracket using distributive property

For the expression 7(5+g)

7(5)+7g

= 35+7g

For the expression 11(3s-4)

= 11(3s)-11(4)

= 33s-44

For the expression 4(4-x)

= 4(4)-4x

= 16-4x

For the expression 8(6+4w)

= 8(6)+8(4w)

= 48+32w

A cylinder has a volume of 288pie cubic meters and a height of 9 meters. What is the area of the base?

Butoxors [25]

  V = πr²h
  288 = 3.14(r²)(9)
  288 = 3.14(9r²)
  288 = 28.26r²
28.26 28.26
10.19 ≈ r²
  3.19 ≈ r

B = πr²
B = 3.14(3.19)²
B = 3.14(10.19)
B = 31.9966

To make five cups of lemonade you mix three cups of water with two cups of lemon juice. If there are sixteen cups in a gallon, h

zvonat [6]

Answer:

64 cups of lemon juice

Explanation:

First, you can determine with the information provided the amount of cups of lemon needed to prepare sixteen cups of lemonade:

5 cups of lemonade→2 cups of lemon juice

16 cups of lemonade→x

x=(16*2)/5=6.4 cups of lemon juice

Now, you now that for sixteen cups that is the amount in a gallon you need 6.4 cups of lemon juice and you can use a rule of three to determine the amount needed for ten gallons of lemonade:

1 gallon of lemonade→6.4 cups of lemon juice

10 galons of lemonade→x

x=(10*6.4)/1=64 cups of lemon juice

According to this, the answer is that 64 cups of lemon juice are needed to make ten gallons of lemonade.
