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.

X=1/2(Outer Arc- Inner Arc)
Our Inner arc is 150, to find the outer arc we do 360-150 which is 210
Now that we have both arcs, we plug them into the equation.
X=1/2(210-150)
X=1/2(60)

Step-by-step explanation:
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]
6 2/3 pounds will be in each container.
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.

Which piecewise function represents the graph?
Answer:
D
Step-by-step explanation:
If you look at the right side of each piecewise function, you will see the x-values. That is what we will be focusing on in this explanation. All four equations have x > 4, and we know that to be true. If you look at the equation on the graph going South West, you will see that the endpoint is at x=1. Only 1 equation, D, has this in the piecewise function. To confirm it is D, you can see that 1<x<4 is also in the piecewise function, and all the values line up with their corresponding y-values.

Gerald would like to add a dental and vision option to the health insurance plan he purchased through his employer. in addition to the 65% of gerald’s $345 monthly health insurance premium, his employer has offered to pay 50% of a $38 monthly dental premium and 75% of a $23 monthly vision premium. if gerald adds both the dental and vision options to his insurance plan, how much will he pay each month towards health insurance? soopergood insurance option monthly premium employer contribution health insurance $345 65% dental $38 50% vision $23 75% a. $141.75 b. $145.50 c. $149.50 d. $260.50
From the calculations, Gerald will now have to pay the sum of $145.50 towards his monthly health insurance.
How is the above sum arrived at?
Note that the first sum being contributed by Gerald is (100%- 65%) of $345. This is 35% of $345 = $120.75
If his employer takes up 50% of $38, this leaves his contribution for dental as 50% of $38 = $19
Also if his employer takes up 75% of $23, his contribtuion for vision premium is 25% of 23 = $5.75
Hence his total contribution is now:
120.75 + 19.00 + 5.75 = $145.50
