Answer:

3 yard roll of wrapping paper for $7.02 is better to buy.

Step-by-step explanation:

1 yard = 3 foot

3 yard = 9 foot

$7.02 / 9 foot = $0.78/foot

$7.36 / 8 foot = $0.92/foot

0.78 < 0.92

Therefore, 3 yard roll of wrapping paper for $7.02 is better to buy.

Answer:

10

Step-by-step explanation:

So you start with

0.10x+0.25(24-x)=4.50

First you do the parenthesis

.25x24 is 6.

So

.10x+6-.25x=4.5

Combine like terms

-.15x+6=4.5

Now isolate the x so you can find what x is

4.5-6

-.15x=-1.5

Then divide

-1.5/-.15

The two negatives make it positive

So 1.5/0.15

Comes to 10.

x=10

The 10 comes like this .15 is 15/100

Simplify that to 3/20

1.5 is 15/10

Simplify that to 3/2

Then divide those

3/2 ÷ 3/20

You cant divide fractions so flip the other side and multiply

3/2 × 20/3

60/6

10

Hope this helps

Answer: Hello There!................

Mean = Sum of observation / total number of observation

Mean = 1.35m

1.35  = Sum of length of 7 wood planks/ 7

1.35*7 = Sum of the length of 7 wood planks

9.45 = Sum of the length of 7 wood planks

Let the length of extra added wood plank = x

So,

(Sum of the length of 7 wood planks + x) / 8 = 1.4m

(9.45 + x) / 8 = 1.4

9.45 + x = 1.4 * 8

9.45 + x = 11.2

x = 11.2- 9.45

= 1.75

So,

The length of extra added wood plank = 1.75m

The equation to represent the given phrase is 2p-4=-12.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given phrase is "Negative twelve is four less than twice a number, p."

Here, four less than twice a number, p is

2p-4

The difference is equal to -12.

Now, 2p-4=-12

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Here, transpose -4 to the other side of an equation, we get

2p=-12+4

2p=-8

p=-2

Therefore, the value of p is -2.

Answer:

Step-by-step explanation:

Keep in mind we read graphs from left to right just like how we read and write.

We can use those tips to solve the problem.

Option A:

4/5 is a positive slope so it will rise from left to right.

Option B:

No slope automatically means "undefined" so that falls in the definition of a vertical line.

Option C:

A slope of 0 is defined as a horizontal line.

Option D:

-4/5 is a negative slope so it will fall from left to right.

Answer:

13x – 7

Step-by-step explanation:

If "a number represents x", then:

The sum of 4 times a number and - 7, added to 9 times the number = (4x + -7) + 9x.

(4x + -7) + 9x →

(4x + 9x) + -7 →

(13x) + -7 →

(13x) – 7 →

13x – 7.

The unknown number will be equal to 4.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the sum of 4 times a number and - 7, added to 9 times the number is 45. The value of the unknown number will be calculated as below:-

The sum of 4 times a number and - 7, added to 9 times the number = (4x + -7) + 9x.

(4x + -7) + 9x = 45

(4x + 9x) + -7 = 45

(13x) + -7 = 45

(13x) – 7 = 45

13x – 7 = 45

13x = 45 + 7

13x = 52

x = 4

Therefore, the unknown number will be equal to 4.
