Answer:
The greater than or equal to sign is:
>= or ≥.
Now let's solve for this inequality.
-8x + 5 ≥ -3
First, we need to get rid of any constants.
Get rid of a constant by performing the inverse operation of it, we always apply this to both sides of an inequality.
The inverse operation of addition (since it is a positive 5) is subtractions.
So, we subtract 5 from both sides;
-5 -5
Now we have:
-8x ≥ -8
Now, all we need to do is isolate x from it's co-efficient, 8.
To do that, we also utilize the inverse operation.
The inverse operation of multiplication (since -8 is being multiplied by x) is division, we apply this to both sides of this inequality.
So, we divide by -8 from both sides;
÷ -8 ÷ -8
And we'll end up with:
x ≥ 1, therefore the solution to this inequality is 1.

Answer:
[tex]3\frac{3}{10}[/tex]
Step-by-step explanation:
Given: diameter = [tex]6\frac{3}{5}[/tex]
This is a mixed number.
We have to convert mixed numbers to improper fractions.
[tex]6*\frac{5}{5}+\frac{3}{5} \\ \frac{30}{5}+\frac{3}{5}=\frac{33}{5}[/tex]
diameter = 33/5
Now diameter = 2*radius so we divide 2 by diameter to get our radius.
[tex]\frac{33}{5} /2=\frac{33}{5}*\frac{1}{2} =\frac{33}{10}[/tex]
Improper fraction back to a mixed number.
10 can go into 33, 3 times so left with a 3 remainder.
[tex]\frac{33}{10}=3\frac{3}{10}[/tex]

Answer:

Step-by-step explanation:

Answer:
x = 6
Step-by-step explanation:
To solve an equation for the value of a variable, undo the operations that are performed on that variable. The Order of Operations tells you the order they are performed. The operations can be undone in the reverse order by making use of inverse operations.
__
Here, x is multiplied by 4 and -8 is added to the product. The opposite of -8 is +8, so we can add that to both sides of the equation to "undo" the addition.
4x -8 = 16 . . . . given
4x -8 +8 = 16 +8 . . . . add the opposite of the constant
4x = 24 . . . . . . . . . . simplify
To undo the multiplication, we multiply by the "multiplicative inverse" or "reciprocal" of the coefficient of x. Again, we do this to both sides of the equation.
(1/4)(4x) = (1/4)(24) . . . . multiply by inverse of 4
x = 6 . . . . . . simplify . . . . this is the value of x you are looking for
_____
Additional comment
This is called a "2-step" linear equation. The two steps are ...
isolate the variable term by adding the opposite of the constanteliminate the variable coefficient by multiplying by its inverseNote that multiplying by 1/4 is the same as dividing by 4. Adding the opposite of a number is the same as subtracting the number.
The properties of equality tell you that you can do anything you like to an equation, as long as you do the same thing to both sides of the equation. When solving equations, this is the one rule that you must never violate.
A baker has 40 pounds of sugar. He plans to store the sugar in 6 equal containers. He must store all of the sugar. How many pounds will be in each container.
40/6 = 6.666... in each container
hope it helps...!!!
Answer:
[tex]6\frac{2}{3}\text{ pounds}[/tex]
Step-by-step explanation:
The baker must have equal amounts in all countainers. Therefore we need to use division to solve this question.
In this scenario we divide the 40 pounds of sugar between the 6 equal containers.Therefore we get:
[tex]\frac{40}{6}[/tex]
Simplify the fraction:
[tex]\frac{20}{3}[/tex]
Write it as a mixed fraction:
20 divided by 3 is 6 with a remainder of 2This means the mixed fraction is:[tex]6\frac{2}{3}[/tex]

Three college refrigerators are on sale at an appliance store. All three have storage areas that are cubes. The first has an internal measurement of 1.5 feet for each side. It costs $98. The second has an internal measurement of 2.1 feet for each side. It costs $142. The third has an internal measurement of 1.75 feet for each side. It costs $124. Comparing the cost per cubic foot, which refrigerator is the best buy?
Please tell me what you did to solve this. Ty!
By taking the quotients between the cost and the volume of each refrigerator, we will see that the best buy is the second option.
How to get the cost per cubic foot?
To get this, we just need to take the quotient between the cost of the refrigerators and their volume.
Remember that the volume of a cube of side length S is V = S^3
For the first one, the cost is $98 and the side length is 1.5ft, so the volume is:
V = (1.5ft)^3 = 3.375 ft^3
The cubic per square foot is:
C = ($98/3.375 ft^3) = $29.04 per cubic foot.
For the second refrigerator, the side length is 2.1 ft and the cost is $142. Then the volume is:
V = (2.1 ft)^3 = 9.261 ft^3
The cost per cubic foot is:
C = ($142/9.261 ft^3) = $15.33 per cubic foot.
For the third refrigerator, the side length is 1.75 ft and the cost is $124.
So the volume will be:
V = (1.75 ft)^3 = 5.3594 ft^3
Then the cost per cubic foot is:
C = ($124/5.3594 ft^3) = $23.14 per cubic foot.
So, as we saw, the best buy will be the second option, because it has the lowest price per cubic foot.

Answer:
[tex]a_{n}[/tex] = 1 + (n-1)84
Step-by-step explanation:
to solve a sequence there's a formula-
[tex]a_{1}[/tex]+(n-1)d
where a1 is the first term, and d is the common difference
since we know the first term, and we have a few subsequent terms we can solve for d and creat the general formula for the nth term
to find d we simply check the difference between two terms-
168-x = 84
168-84 = x
84 = x
we can confirm this by checking the next two even
252- x = 168
252 - 168 = x
84 = x
now we have enough for a general formula
[tex]a_{n}[/tex] = 1 + (n-1)84

The term used to describe this phenomenon of future generation fluctuations would be Genetic drift.
What is Genetic drift?Genetic drift refers to the random fluctuations in the number of offspring in a population.
Rabbits can exhibit several colors in their coats: black, white, tan, brown, red, and grey.
A disease randomly kills off most of the population and leaves only black and grey rabbits.
Future generations are only black or grey. We can see that the future rabbits have some common colors that are given by their parents.

A. Zero product property
B. quadratic formula
C. square root property
The value of x by using the zero product property therefore option A is correct.
We have given that,
(x+3)(x+2)=0
we have to determine the technique that is most appropriate to use to solve each equation
What is the zero product property?The Zero Product Property simply states that if ab = 0, then either a = 0 or b = 0 (or both).
Therefore we have
(x+3)=0 and (x+2)=0
This implies that,
x+3=0
x=-3 and (x+2)=0 this implies that x=-2
Therefore we get the value of x by using the zero product property therefore option A is correct.
