Henry is three more than twice Nicholas’ age. Marcus is 9 less than six times Nicholas’s age. If Henry and Marcus are twins, how old is Nicholas?

Answers

Answer 1

Answer:

Step-by-step explanation:

Henry is 3 more than twice Nicholas' age. You can write this as :

H = 3 + 2N

Marcus is 9 less than 6 times Nicholas' age:

M = 6N - 9

Since Henry and Marcus are twins, this means H = N.

3 + 2N = 6N - 9

Add 9 to both sides

12 + 2N = 6N

Subtract 2N from both sides

12 = 4N

Divide both sides by 4 to find N.

N = 12/4 = 3

Answers

I can’t upload any working right now so I hope you’ll understand from an explanation, all it is is a hidden polynomial. You can say:

Let y=x^2
Then the equation becomes:
y^2 - 18y + 81
Factorise that to give you:
(y-9)(y-9) Or (y-9)^2
But remember, y=x^2. So the equation becomes:
(X^2-9)(X^2-9)

So... I looked up this question before asking BUT some people said it was wrong ???? so I wanted to get some second opinions.

Answers

3 is the greatest common factor, because both numbers are divisible only by 3.

Answer:

The GCF Of 9 and 12 is 3.

Step-by-step explanation: Okay so first lets multiply! 3x1 Is 3 3x2 is 6 and 3x3 is 9, 3 x 4 equals 12! Since they both can be divided by 3, Example 12 divided by 3= 4 9 divided by 3= 3, therefore they have a GCF of 3. Remember, this is the greatest factor, not Multiple.

Identify whether this will be normal distribution or skewed left or right? (Hint: find the five number summary and make a box plot)

O normal distribution

Answers

The answer is skewed in the right direction

The distribution of set A is a normal distribution

5

Notice that the plot above increase from 0, then reaches a maximum at 3, and then decreases from 3 to 5

This implies that it follows a bell curve.

When a distribution follows a bell curve, such data is a normal distribution.

Hence, the distribution is a normal distribution

Answer:

All real numbers

Step-by-step explanation:

Answer:

C) all real numbers

Step-by-step explanation:

4(a + 3) = 12 + 4a

open the parenthesis

4*a + 3*4 = 12 + 4a

4a + 12 = 12 + 4a

subtract 4a from both sides of the equation

12 = 12

Cyclone cleared leaves from the same number of yards
each day for 5 days. Then on day 6, he cleared the leaves
from 8 more yards. He cleared 133 yards in all.

Answers

Answer:

Number of yards per day = 20.83 yard (Approx)

Step-by-step explanation:

Assume;

Number of yards = x per day

Number of yards on 6th day = x + 8

Total yards = 133

Find:

Number of yards per day

Computation:

Total yards = 5[x] + x + 8

133 = 6x + 8

6x = 125

x = 20.83 yard

Number of yards per day = 20.83 yard (Approx)

Answer:

20.83 yards

Step-by-step explanation:

Calculate Cubic Yards

Calculate your area

Calculate your volume: Multiply area times the depth to get volume in cubic feet

Calculate your cubic yards: Divide cubic feet by 27 to convert to cubic yards and this is your answer

Where ft2 = square foot, ft3 = cubic foot, yd3 = cubic yard

Total yards = 5[x] + x + 8  

Solve

133 = 6x + 8

6x = 125

x = 20.83 yard

Therefore, the Cyclone cleared 20.83 yards on the first day.

Answer:

A. x ≥ -3 and x < 2, or -3 ≤ x < 2

Step-by-step explanation:

Remember solid dot means include, open dot means not include.

x ≥ -3: this means x is greater and equal (includes) -3.

x < 2: this means x is less than 2 and does not include it.

Answer:

A

Step-by-step explanation:

So on the number line you see a closed circle at -3 and an open circle at 2.

Closed circle represents it's either [tex]\leq[/tex] or [tex]\geq[/tex]. Open circle represents < or >.

So the first part has a closed circle at -3 and goes towards the right side. Since it does that, it would be [tex]x \geq -3[/tex].

The second part has an open circle at 2 and goes towards the left side. Since it does that, it would be [tex]x < 2[/tex].

To combine it together, it would get [tex]-3 \geq x < 2[/tex].

Since option A is [tex]x \geq -3[/tex] and  [tex]x < 2[/tex], or [tex]-3 \geq x < 2[/tex], A would be the answer.

the perimeter of the triangle below is 38 units. Find the length of side WX. Write your answer without variables

Answers

Answer:

5.5

Step-by-step explanation:

Add each side of the triangle.

3z+z+1+4z-3 = 8z - 2

8z - 2 is equivalent to the  perimeter.

Since you know the perimeter is 38 units, you can set 8z-2 to 38.

8z-2 = 38

Solve for z. Subtract 2 from each side.

8z = 36

Divide each side by 8.

z = 4.5

Now solve for side WX.

WX = z + 1

WX = 4.5 + 1

WX = 5.5
