Answer:
A
B
E
Step-by-step explanation:
For A, we can simplify it to 2c + 2d by combining like terms. We can then factor out 2 and get 2(c + d).
For B, we combine like terms and 7y - x. We can move the x in front and get -x + 7y.
For E we can factor out 2 and get 2(2j + 3k).

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]

Write an equation to describe the sequence below. Use n to represent the position of a term in the sequence, where n=1 for the first term. 84, 168, 252, 336, ... an
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 total closing cost is 3. 5% of the amount of the mortgage. So, the total amount would be $10500.

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]

Answer:

Step-by-step explanation:
im smart this is the answer i swear to ahead and try it yw
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.

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.
