The value of the equation 3ab - 9ab + 7ab is [tex]\boxed{ab}[/tex].

Further explanation:

There are two properties.

1. The property of addition or property of sum.

2. The property of subtraction.

3. The property of division.

4. The property of multiplication.

Given:

The equation is 3ab - 9ab + 7ab.

Explanation:

Consider the equation S = 3ab - 9ab + 7ab.

The equation contains the two variables that are “a” and “b”.

In the equation we have two operations one is addition and another is subtraction.

Solve the above equation to obtain the value of the equation.

First add 3ab and 7ab.

[tex]\begin{aligned}X&=3ab+7ab\\&=10ab\\\end{aligned}[/tex]

Now subtract 9ab from 10ab.

[tex]\begin{aligned}S&=10ab-9ab\\&=1ab\\&=ab\\\end{aligned}[/tex]

The value of S is ab.

Hence, the value of the equation 3ab - 9ab + 7ab is [tex]\boxed{ab}[/tex].

The interest for each loan is $40.32, $4, $175 and $468 respectively.

The formula to find the simple interest is S.I=P×T×R/100.

Where, P=Principal, T=Time period and R=Rate of interest.

With P=$252, T=2 years and R=8%.

Now, SP=252×2×8/100=$40.32

With P=$400, T=6 months (0.5 years) and R=2%.

Now, SP=400×0.5×2/100=$4

With P=$5000, T=1 year and R=3.5%.

Now, SP=5000×1×3.5/100=$175

With P=$6,240, T=9 months (0.75 years) and R=10%.

Now, SP=6,240×0.75×10/100=$468

Therefore, the interest for each loan is $40.32, $4, $175 and $468 respectively.

The converse, inverse, and contrapositive of the given statement are provided. They are logically consistent with the original statement, pointing to the synonymous relationship between congruence and identical length in segments. The additional statement about angles is also factual, as one greater than an acute angle is, by definition, an obtuse.

1.) Converse: If two segments have the same length, then they are congruent.
2.) Inverse: If two segments are not congruent, then they do not have the same length.
3.) Contrapositive: If two segments do not have the same length, then they are not congruent.

The contrapositive is true because it is a logical inverse of the original statement, which is also true. In geometry, congruent means being of the same size and shape, which directly implies having the same length.

4.) The statement: 'If m∠A is greater than an acute ∠B, then ∠A must be obtuse' is true. An acute angle is one that is less than 90 degrees. If ∠A is greater than this, it must be between 91 and 180 degrees, which by definition, makes it an obtuse angle.

Rammy can buy 5 pounds or less of peaches that is x ≤ 5. Then the correct option is B.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

Rammy has $9.60 to spend on some peaches and a gallon of milk. Peaches cost $1.20 per pound, and a gallon of milk costs $3.60.

The inequality 1.20x + 3.60 ≤ 9.60 models this situation, where x is the number of pounds of peaches.

Then the number of pounds of peaches can Rammy buy will be

1.20x + 3.60 ≤ 9.60

           1.20x ≤ 6

Answer:

[tex]AC=25[/tex]

Step-by-step explanation:

From the given figure, it can be seen that [tex]{\angle}A={\angle}C[/tex], thus ΔABC is an isosceles triangle.

Therefore,[tex]AB=BC[/tex]

⇒[tex]5x+5=7x-1[/tex]

Solving the above equation, we get

⇒[tex]5x-7x=-1-5[/tex]

⇒[tex]-2x=-6[/tex]

⇒[tex]x=3[/tex]

Now, substituting the value of x in AC, we have

⇒[tex]AC=6x+7[/tex]

⇒[tex]AC=6(3)+7[/tex]

⇒[tex]AC=18+7[/tex]

⇒[tex]AC=25[/tex]

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Mr. Staley has $62 to buy binders for his mathematics class.

And, The cost of each binders = $3

Now,

Since, The cost of each binders = $3

Hence, Number of binders = $62 / $3

                                          = 20.67

Since, We get the remainder 2 and the quotient is 20.

So, we get;

The dog  is rather running towards the trainer to receive a treat. So it is the second answer.

Answer:

[tex]m\angle WYX=20^{\circ}[/tex]

[tex]m\angle WYZ=70^{\circ}[/tex]

Step-by-step explanation:

We have been given that [tex]m\angle WYX=(4x-8)^{\circ}[/tex] and [tex]m\angle WYZ=(10x)^{\circ}[/tex].

Since ∠WYX and ∠WYZ are complementary, so they will add up-to 90 degrees.

[tex]m\angle WYZ+m\angle WYX=90^{\circ}[/tex]

Substitute the given values:

[tex]4x-8+10x=90[/tex]

Combine like terms:

[tex]14x-8=90[/tex]

[tex]14x-8+8=90+8[/tex]

[tex]14x=98[/tex]

[tex]\frac{14x}{14}=\frac{98}{14}[/tex]

[tex]x=7[/tex]

Let us substitute [tex]x=7[/tex] in measure of each angle as:

[tex]m\angle WYX=(4(7)-8)^{\circ}[/tex]

[tex]m\angle WYX=(28-8)^{\circ}[/tex]

[tex]m\angle WYX=20^{\circ}[/tex]

Therefore, the measure of angle WYX is 20 degrees.

[tex]m\angle WYZ=(10x)^{\circ}[/tex]

[tex]m\angle WYZ=(10(7))^{\circ}[/tex]

[tex]m\angle WYZ=70^{\circ}[/tex]

Therefore, the measure of angle WYZ is 70 degrees.

Step-by-step explanation:

Whatever color the sister choses is irrelevant, eliminating answers A and B, but it does change the odds. If there are 5 red balloons and 4 blue balloons, if the sister is given a blue balloon, the odds of the brother receiving a red balloon increases (vis versa).

Rewrite the given equation in slope intercept form:

5 y = 10 – 2 x

y = - 0.4 x + 2

Since the two lines are parallel, therefore they have similar slope which is – 0.4, so the equation is:

y = - 0.4 x + b

Given that x = 5, y = -4, find for b:

-4 = - 0.4 (5) + b

b = -2

So the answer is:

y = - 0.4 x – 2

or

2 x + 5 y = - 10

The graph represents the function y = (x - 1), as per linear equation.

A linear equation represents an equation that has one or multiple variables with the highest power of the variable is 1.

The given equation is:

y - 3 = x - 4

⇒ y = x - 1

Therefore, for x = 0, y = - 1

for x = 1, y = 0

for x = - 1, y = - 2

Therefore, the graph will pass through points (0, - 1), (1, 0), (- 1, - 2).

Answer:

Volume of the cone is [tex]\frac{1}{12}\pi r^{3}[/tex]

Step-by-step explanation:

Formula to find the volume of a cone is V = [tex]\frac{1}{3}\pi r^{2}h[/tex]

Here r is the radius of the cone and h is the height of the cone.

Since radius of cone = [tex]\frac{1}{2}(\text{Radius of cylinder})[/tex]

                                  = [tex]\frac{r}{2}[/tex]

Height of the cone = radius of the cylinder = r

Now we put the values of radius and height of cone in the formula

Volume of cone = [tex]\frac{1}{3}\pi (\frac{r}{2})^{2}(r)[/tex]

= [tex]\frac{1}{3}\pi(\frac{r^{2}}{4})(r)[/tex]

Therefore, volume of the cone is [tex]\frac{1}{12}\pi r^{3}[/tex]

The width of the porch is 5 feet.

Let's denote the width of the porch as x. The length of the porch is then x + 4. The area of a rectangle is given by length x width. So, we can set up the equation x(x + 4) = 75 to find the width of the porch. Expanding the equation, we get x² + 4x = 75. Rearranging the equation, we have x² + 4x - 75 = 0. This quadratic equation can be factored as (x - 5)(x + 15) = 0. Since the width of the porch cannot be negative, we discard the x + 15 = 0 solution. Therefore, the width of the porch is 5 feet.

Final answer:

To find the cost of each slice of white chocolate torte, divide the total cost to produce two tortes ($11.90) by the total number of slices (16), resulting in approximately 74 cents per slice.

Explanation:

Cost of Each Slice of White Chocolate Torte

To calculate the cost of each slice of white chocolate torte, we start by determining the total cost of producing the tortes. The restaurant's cost is $11.90 for 2 tortes, and each torte is cut into 8 slices. This means there's a total of 2 tortes × 8 slices/torte = 16 slices. Dividing the total cost by the number of slices gives us the cost per slice:

Total cost for 2 tortes: $11.90

Number of slices per torte: 8

Total number of slices: 2 tortes × 8 slices/torte = 16 slices

Cost per slice: $11.90 / 16 slices = $0.74375 per slice

Therefore, each slice costs approximately 74 cents to make.

Answer:

The original price of socks was $8.

Step-by-step explanation:

James buys a shirt and a pair of socks on sale for 25% off.

The price of the shirt before the sale was $24 that means after discount the price was:

[tex]24-(0.25\times24)[/tex] = $18

And James paid a total of $24.

That means the price of socks after discount is = [tex]24-18[/tex] = $6

Let the original price of socks be x. And after 25% discount, it was for $6.

So, [tex]x-0.25x=6[/tex]

=> [tex]0.75x=6[/tex]

x = 8.

Hence, the original price of socks was $8.
