What value would make the equation 8x = -72 true?
Answer:x= -9
Step-by-step explanation: You would dive both sides by 8 and -72 divided by 8 is -9
Answer:-9
Step-by-step explanation:
The answer is -9 because we are solving to get x by itself. Since 8 is being multiplied by x the opposite of multiplication is division. Divide both sides by 8 to get x by itself. -72 divided by 8 is -9 because a negative divided or multiplied by a positive is a negative. To check your work you can do 8 times -9 which equals -72.

The figures below show the front view and top view of a rectangular prism that is packed with unit cubes. What is the volume of the prism if there are no gaps or overlaps in the unit cubes? ____ cubic unit
Answer:
60 cubic units
Step-by-step explanation:
The figure is 5 tall, so just add 5 for each square on the top view.
The volume of the rectangular prism is 60 cubic units
What is the Volume of a Rectangle?
The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle
Volume of Rectangle = Length x Width x Height
Volume of Rectangle = Area of Rectangle x Height
Given data ,
Let the volume of the rectangular prism be represented as V
Now , the equation will be
The length of the rectangular prism = 3 units
The width of the rectangular prism = 4 units
The height of the rectangular prism = 5 units
Now , the volume is calculated by
Volume of Rectangle = Length x Width x Height
Substituting the values in the equation , we get
Volume of Rectangle V = 3 x 4 x 5
On simplifying the equation , we get
Volume of Rectangle V = 60 cubic units
Therefore , the value of V is 60 cubic units
Hence , the volume of the rectangular prism is 60 cubic units

That order is taken into account (consider rearrangements of the same items to be different sequences). B. That r of the n items are selected (without replacement). C. That there be n different items available. D. That order is not taken into account (consider rearrangements of the same items to be the same).
Answer: A. That order is taken into account (consider rearrangements of the same items to be different sequences).
Step-by-step explanation:
The combination is usually given by the formula below:
C n,x = n! / x! (n-x)!
We should note that the requirements for a combination rule include:
• That r of the n items are selected (without replacement).
• That there be n different items available.
• That order is not taken into account (consider rearrangements of the same items to be the same).
Therefore, the option that is not a requirement of the Combinations Rule, , for the items that are all different will then be option A"That order is taken into account (consider rearrangements of the same items to be different sequences).

A 10-ounce container of chocolate chips can be used to make 4 desserts.
Each dessert has the same number of chocolate chips.
Which equation shows how to find the number of ounces in each dessert?
A number line going from 0 to 10 in increments of 1.
10÷4=104 ounces
4÷10=104 ounces
10÷4=410 ounce
4÷10=410 ounce
Answer:
So equation will be 4x = 10
A 10 ounce container of chocolate chips can be used to make 4 desserts.
Each desert has the same number of chocolate chips
Let number of chocolate chips in each dessert = x ounce
Therefore, chocolate chips in 4 deserts = 4x and total chocolate chips is = 10 ounce.
So equation will be 4x = 10

There are 90 million pet dogs in the US. The number of dogs is 1000% the number of reptiles. How many reptiles are there?
Answer:
There are 9 000 000 = 9 million reptiles in the US.
Step-by-step explanation:
Percentages and ratio:
The double of a measure, for example, is 200% of the measure.
So 1000% of a measure is 10 times the measure.
There are 90 million pet dogs in the US. The number of dogs is 1000% the number of reptiles.
The number of pet dogs is 10 times the number of reptiles, which means that:
[tex]10x = 90 000 000[/tex]
[tex]x = \frac{90 000 000}{10}[/tex]
[tex]x = 9 000 000[/tex]
There are 9 000 000 = 9 million reptiles in the US.

help lol solve for x
Answer:
x = 6
Step-by-step explanation:
(8x - 4)° + (3x + 17)° = (17x - 23)° => exterior angle theorem
Solve for x
8x - 4 + 3x + 17 = 17x - 23
Add like terms
11x + 13 = 17x - 23
11x - 17x = -13 - 23
-6x = -36
Divide both sides by -6
x = 6

The required value of altitude y is 9 units which is determined by the geometric theorem.
What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
As we know that the geometric theorem states that h = √(ab),
where h is the altitude of a right triangle, a and b are the segments formed when the altitude divides the hypotenuse of a right triangle.
We have to determine the value of altitude y
As per the given figure, a = 3, and b = 27
Substitute the values in the formula, and we get
y = √(3 × 27)
y = √81
y = 9
Therefore, the measure of y = 9.

Find the value of a and the area of the triangle. Round to the nearest hundredth
Answer:
a = 6.65
Area = 15.84
Step-by-step explanation:
By cosine rule in the given triangle,
BC² = AC² + AB² - 2(AC)(AB)cos(C)
a² = 5² + 9²- 2(5)(7)cos(28°)
a² = 25 + 81 - 61.81
a = [tex]\sqrt{44.19}[/tex]
a = 6.65
Area of a triangle with given three sides = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]
Here, s = Average of lengths of all sides
a, b and c are the measures of the respective sides of the triangle.
s = [tex]\frac{6.65+7+5}{2}[/tex]
s = 9.325
a = 6.65, b = 5 and c = 7
Now substitute these values in the formula to get the area,
Area = [tex]\sqrt{9.325(9.325-6.65)(9.325-5)(9.325-7)}[/tex]
= [tex]\sqrt{9.325\times 2.675\times 4.325\times 2.325}[/tex]
= [tex]\sqrt{250.8313}[/tex]
= 15.838
= 15.84
