Answer:

9/24

Step-by-step explanation:

Answer:

y = 3x - 2

3x - y = 2

y = 2(x + 3)

Step-by-step explanation:

y = the larger number

x = the smaller number

A larger number is double the sum of 3 and a smaller number

y = 2(x + 3)

y = 6 + 2x

The larger number is 2 less than 3 times the smaller number.

y = 3x - 2

Make -2 the subject

y - 3x = -2

Make 2 the subject

y = 3x - 2

y - 3x = -2

(y - 3x) * -1 = -2 * -1

-y + 3x = 2

3x - y = 2

The answers:

y = 3x - 2

3x - y = 2

y = 2(x + 3)

Here is what I got hope it helps!!!!!!!

Step-by-step explanation:

Equivalent expressions are expressions with the same value.

The proper way to rewrite the equation is: [tex]\mathbf{(x + y)^2 = x^2 + 2xy + y^2 }[/tex]

Jonah's equation is given as:

[tex]\mathbf{(x + y)^2 = x^2 + y^2}[/tex]

To convince Jonah that Jonah's equation is wrong, Graham can do any of the following

Assume value for x and y

Let x = 2 and y = 4

[tex]\mathbf{(2 + 4)^2 = 2^2 + 4^2}[/tex]

[tex]\mathbf{36 = 20}[/tex]

The above equation is false.

So, it means that: [tex]\mathbf{(x + y)^2 \ne x^2 + y^2}[/tex]

Expand the equation

We have:

[tex]\mathbf{(x + y)^2 = x^2 + y^2}[/tex]

Open the bracket

[tex]\mathbf{x^2 + 2xy + y^2 = x^2 + y^2}[/tex]

Cancel out common terms

[tex]\mathbf{2xy = 0}[/tex]

The above equation is false.

So, it means that: [tex]\mathbf{(x + y)^2 \ne x^2 + y^2}[/tex]

The proper way to rewrite the equation is:

[tex]\mathbf{(x + y)^2 = x^2 + 2xy + y^2 }[/tex]

Answer:

Step-by-step explanation:

-5(z + 1) = -2z + 10           Remove the brackets

-5z - 5 = - 2z + 10            Subtract 10 from both sides

   - 10           - 10

-5z - 15 = -2z                   Add 5z to both sides

+5z          +5z

    -15  = 3z                     Divide by 3

z = - 5

Answer:

81.64

Step-by-step explanation:

formula for volume of a cylinder is pi times radius squared times height

the radius here is 2, and the height is 6.5

plug the numbers into the formula and you get pi(2^2)(6.5), which is 81.64

Find where the curve intersects the x-axis; this happens when y = 0:

y = t - t ² = 0   →   t (1 - t ) = 0   →   t = 0, t = 1

Then the area of the bounded region is

[tex]\displaystyle\int_0^1 y(t) x'(t)\,\mathrm dt=\int_0^1 (t-t^2)e^t\,\mathrm dt=\boxed{3-e}[/tex]

(you can compute the integral by parts)

Answer:

Each will receive [tex]\frac{1}{6}th[/tex] of the cake.

Step-by-step explanation:

Let the amount of cake = c

Lisa, Juan and Isaac are the persons who are sharing half of a cake equally.

Number of persons = 3

Part of the cake shared = [tex]\frac{c}{2}[/tex]

Fraction of the cake shared by each = [tex]\frac{\text{Amount of cake shared}}{\text{Number of persons who shared}}[/tex]

                                                             = [tex]\frac{\frac{1}{2}c}{3}[/tex]

                                                             = [tex]\frac{1}{6}c[/tex]

Therefore, fraction of total cake shared by each member will be [tex]\frac{1}{6}[/tex] of the total amount of cake.

The correct answer is A

Answer:

1. There is sufficient evidence to conclude that listening to soothing sounds increases the mean test score.

Step-by-step explanation:

A  p - value less than 0.05  means that the test hypothesis is false or rejected.

In this question the test hypothesis is H 0 : mu=79  which is false as p-value is 0.035.

Whenever the p- value is less than the significance level H0 is rejected.

Hence the null hypothesis is rejected.

Therefore only choice 1 is correct.

There is  sufficient evidence to conclude that listening to soothing sounds increases the mean test score.

There is sufficient evidence to support the claim.

The value of expression after subtraction is,

⇒ - 0.177

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

Expression is,

⇒ 0.123 - 0.3

Now, We can simplify the expression by subtracting as;

⇒ 0.123 - 0.3

⇒ - 0.177

Thus,  The value of expression after subtraction is,

Answer:

there would be 1 ÷ 6 sugar in each month

Step-by-step explanation:

The computation of the customers that want to know the sugar in each muffin is shown below

Here we assume the sugar in each muffin be x

Now there is 30 cups and 10 cups should be used for making some cookies

And, the rest would be use for making 144 gaint muffins

So, the equation that should be used is

10 + 144x = 34

144x = 24

x = 1 ÷ 6

So there would be 1 ÷ 6 sugar in each month
