Solve the following equation. 6x−15=4x+55 6 x − 15 = 4 x + 55
Answer:
x = 35
Step-by-step explanation:
Solve for x:
6 x - 15 = 4 x + 55
Hint: | Move terms with x to the left hand side.
Subtract 4 x from both sides:
(6 x - 4 x) - 15 = (4 x - 4 x) + 55
Hint: | Combine like terms in 6 x - 4 x.
6 x - 4 x = 2 x:
2 x - 15 = (4 x - 4 x) + 55
Hint: | Look for the difference of two identical terms.
4 x - 4 x = 0:
2 x - 15 = 55
Hint: | Isolate terms with x to the left hand side.
Add 15 to both sides:
2 x + (15 - 15) = 15 + 55
Hint: | Look for the difference of two identical terms.
15 - 15 = 0:
2 x = 55 + 15
Hint: | Evaluate 55 + 15.
55 + 15 = 70:
2 x = 70
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 2 x = 70 by 2:
(2 x)/2 = 70/2
Hint: | Any nonzero number divided by itself is one.
2/2 = 1:
x = 70/2
Hint: | Reduce 70/2 to lowest terms. Start by finding the GCD of 70 and 2.
The gcd of 70 and 2 is 2, so 70/2 = (2×35)/(2×1) = 2/2×35 = 35:

Imagine a spherical cell with a radius of 10 pm. What is the cells surface area in pm2? Its volume, in pm3? What is the ratio of surface area to volume for this cell? Now do the same calculations for a second cell, this one with a radius of 20 pm. Compare the surface-to-volume ratios of the two cells. How is this comparison significant to the functioning of cells? (Note. For a sphere of radius r, surface area = 4rcr2 and volume = rrr3. Remember that the value of it is 3.14.)
Answer:
comparing the two cells, we can see that the surface area to volume ratio gets smaller as the cell gets bigger, making it harder for optimum amount of material that is needed to sustain the cell to cross the cell membrane. If a cell should grow beyond a certain limit, enough material will not be able to cross the membrane to nourish the cellular volume.
Step-by-step explanation:
For the cell with radius r = 10 pm
The surface area is from the area of a sphere
Area A = [tex]4\pi r^{2}[/tex]
A= 4 x 3.14 x [tex]10^{2}[/tex] = 1256 pm^2
volume is calculated from the volume of a sphere
Volume V = [tex]\frac{4}{3}\pi r^3[/tex]
V = [tex]\frac{4}{3}[/tex] x 3.14 x [tex]10^{3}[/tex] = 4186.67 pm^3
Ratio of surface area to volume = 1256/4186.67 = 0.29
For the second cell with radius r = 20 pm
The surface area of the cell is
A = [tex]4\pi r^{2}[/tex] = 4 x 3.14 x [tex]20^2[/tex] = 5024 pm^2
Volume = [tex]\frac{4}{3}\pi r^3[/tex] = [tex]\frac{4}{3}[/tex] x 3.14 x [tex]20^{3}[/tex] = 33493.3 pm^3
Ratio of surface area to volume = 5024/33493.3 = 0.15
comparing the two cells, we can see that the surface area to volume ratio gets smaller as the cell gets bigger, making it harder for optimum amount of material that is needed to sustain the cell to cross the cell membrane. If a cell should grow beyond a certain limit, enough material will not be able to cross the membrane to nourish the cellular volume.

~Subtract m to both sides
56 = 0
No solution
Best of Luck!
Answer:
no solution
In-depth explanation:
Hi there, let's solve this equation.
For now, I will focus on the left side & combine the like terms:
[tex]\tt{m+55+1=m}[/tex]
[tex]\tt{m+56=m}[/tex]
Subtract 56 from each side:
[tex]\tt{m=m-56}[/tex]
Subtract m from each side:
[tex]\tt{m-m=-56}[/tex]
[tex]\tt{0=-56}[/tex]
Therefore, the equation has no solution.

Jamie makes plates and bowls. She needs to ship 48 plates and 54 bowls to a store. She wants to ship the same number of items in each box. Plates and bowls are shipped separately. A.What is the greatest number of items she can ship in each box?
Answer: 6
Step-by-step explanation:
Given, Jamie needs to ship 48 plates and 54 bowls to a store.
If she wants to ship the same number of items in each box such that plates and bowls are shipped separately. .
then the greatest number of items she can ship in each box = GCD (48,54)
[GCD = Greatest common divisor]
Prime factorization of both numbers:
48 = 2 x 2 x 2 x 2 x 3
54 = 2 x 3 x 3 x 3
GCD (48,54)= 2 x 3 = 6
Hence, the greatest number of items she can ship in each box =6
Answer:6
Step-by-step explanation:
So here's the problem writen down.
48 = 2 x 2 x 2 x 2 x 3
54 = 2 x 3 x 3 x 3
GCD (48,54)= 2 x 3 = 6

3n-5=-8(6+5n) in distributive property
Answer:
n=-1
Step-by-step explanation:
3n-5=-8(6+5n)
3n-5=-48-40n
add 40n to both sides
43n-5=-48
n=-1
Using distributive property we can expand the expression as
3n - 5 = -8 x 6 + (-8) x 5n
To apply the distributive property to the equation
3n - 5 = -8(6 + 5n), we need to distribute the -8 to the terms inside the parentheses.
Using the distributive property, we have:
3n - 5 = -8 x 6 + (-8) x 5n
Simplifying further:
3n - 5 = -48 - 40n
Now, we can continue solving the equation using the simplified form as
3n + 40n = -48 + 5
43n = -43

The ______ of a function is the complete set of inputs, whereas the _______ is the set of all outputs
Answer:
Domain, range
Step-by-step explanation:
The domain of a function is the complete set of inputs, whereas the range is the set of all outputs.
Domain= Input
Range= Output
The domain of a function is the complete set of inputs, whereas the range is the set of all outputs.
What are the domain and range of the function?The domain of the function includes all possible x-values of a function, and the range includes all possible y-values of the function.
The domain of a function refers to all the possible input values that can be plugged into a function and produce a valid output. It represents all the values that are allowed as inputs to the function.
The range of a function refers to all the possible output values that can be produced by the function. It represents the set of all values that the function can produce as outputs, given the inputs from the domain.
So, the domain represents the set of all possible inputs to the function, and the range represents the set of all possible outputs of the function.
