Determine the value of y, if x is 3.
y = | x | + 5
Answer:

Answer:

See below.

Step-by-step explanation:

So, we know that Noah's purchase can be modeled by the equation:

[tex]x-0.1x+2.70=56.70[/tex]

Part 1)

The solution to the equation will be the value of x.

In this case, x will represent the original price of the jeans.

We know that Noah has a coupon for 10% off the original price of the jeans.

So, 0.1x will represent how much of the original price Noah gets a a discount on.

Therefore, (x - 0.1x) represents the total cost of the jeans after the coupon.

So, x is our original price of the jeans.

Part 2)

To verify that 70 is not a solution, we can simply substitute 70 for x and check whether or not the equation is true. So:

[tex](70)-0.1(70)+2.7\stackrel{?}{=}56.70[/tex]

Multiply:

[tex]70-7+2.7\stackrel{?}{=}56.7[/tex]

Subtract:

[tex]63+2.7\stackrel{?}{=}56.7[/tex]

Add:

[tex]65.7\neq56.7[/tex]

However, we can verify that 60 is the solution by substituting. So, substitute 60 for every x:

[tex](60)-0.1(60)+2.7\stackrel{?}{=}5.7[/tex]

Multiply:

[tex]60-6+2.7\stackrel{?}{=}56.7[/tex]

Subtract:

[tex]54+2.7\stackrel{?}{=}56.7[/tex]

Add:

[tex]56.7\stackrel{\checkmark}{=}56.7[/tex]

So, 60 is indeed the solution and is the value of x.

So, this means that $60 was the original price of the jeans.

$60

In order to find median you need to find the middle number of the set by crossing each one out until you get to the middle. I hope this helps!

Answer:

19.

Step-by-step explanation:

Answer:

The required number  = 19

Step-by-step explanation:

307 - 3 = 304

330 - 7 = 323

Find GCF of 304 & 323

304 =  2* 2 *2 * 2 * 19

323 = 17 *19

HCF = 19

The required number  = 19

When you divide 307 by  19, you will get an remainder 3

When you divide 330 by  19, you will get an remainder 7

Answer:

X = - 2 or X = 2

Step-by-step explanation:

*completing the square*

X^2 - 4 = 0

X^2 = 4

X = +-√4

x = +-2

x= -2, 2

*factoring*

X^2 - 4 = 0

(x-2)(x+2) = 0

|. |

x = 2, x = -2

________________________________

(x-2)(x+2) = x(x+2) - 2(x+2) = x^2 + 2x - 2x - 4 = x^2-4

Answer:

Irrational number between 2 and 2.5 = √2*2.5 = √5

Step-by-step explanation:

2 < √5 < 2.5

We know that √5 is an irrational number.

So, √5 is the required irrational number between 2 and 2.5.

Answer:

Acute triangle because the angles are smaller than a right triangle  

Step-by-step explanation:

As 5² + 4² < 8² it falls into the category of a² + b² < c², therefore it is an acute angle triangle.

If a² + b² < c² then it is an acute angle triangle.

If a² + b² = c² then it is a right-angle triangle.

If a² + b² ≥ c² then it is an obtuse angle triangle.

Given, A triangle has sides measuring 8 inches, 5 inches and 4 inches.

So, 5² + 4² ? 8².

25 + 16 ? 64.

41 ? 64.

So, 41 < 64 therefore it is a² + b² < c² then it is an acute angle triangle.

Answer:

1.45

Step-by-step explanation:

1.45 is already rounded to the nearest hundredth..

Answer:

1.45 (no need to round)

Step-by-step explanation:

When looking at this question we can clearly see that there are only 2 numbers behind the decimal.

We know that the number closet to the decimal is the tenths place.

And that the number second closet to the decimal is the hundredths place.

And that the number third closet to the decimal is the thousandths place.

Since there is no thousandths place we can't round the 5 up.

Which is why your answer is 1.45

3.8

Step-by-step explanation:

Answer:

1. linear pair

2.  Substitution Property of Equality

3. Subtraction Property of Equality

4.  <1  ≅ <3

Step-by-step explanation:

1. linear pair

A linear pair is a pair of angles that  that are adjacent and add to 180 degrees

linear Pair Postulate states: "If two angles form a linear pair, then the angles are supplementary.

2.  Substitution Property of Equality

<1 + <2 = 180  and <2+ <3 = 180

<1 + <2 = <2 + <3

3. Subtraction Property of Equality

<1 + <2  - <2= <2 - <2+ <3

<1 = <3

4.  <1  ≅ <3

Step-by-step explanation:

If two number cubes are rolled, the odds in favor of getting two numbers less than 3 is 1 : 9.

Probability determines the odd that an event would happen. The odd the event occurs is 1 and the odd that the event does not occur is 0.

Odds in favor of getting two numbers less than 3 = (numbers less than 3 / total numbers) x (numbers less than 3 / total numbers)
