Three times Mary’s age added to Beth’s age is 34 years. Half of Mary’s age minus Beth’s age is 1 year. How old are Mary and Beth?
The age of Mary and the age of Beth will be 10 years and 4 years, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Three times Mary’s age added to Beth’s age is 34 years. Half of Mary’s age minus Beth’s age is 1 year.
Let 'x' be the age of Mary and 'y' be the age of Beth. Then the equations are given below.
3x + y = 34 ...1
x/2 - y = 1 ...2
From equations 1 and 2, then we have
3(2y + 2) + y = 34
6y + 6 + y = 34
7y = 34 - 6
7y = 28
y = 4
Then the value of the variable 'x' is given as,
3x + 4 = 34
3x = 30
x = 10
The age of Mary and the age of Beth will be 10 years and 4 years, respectively.

What is the density at 20oC of 12.0 milliliters of a liquid that has a mass of 4.05 grams?
(if you don't know don't answer it please)
Answer:
Density is defined as mass per unit volume:
density = mass/volume
Density can be calculated using the mathematical formula (expression):
d = m ÷ V
where d = density, m = mass, V = volume
The greater the density, the more mass per unit volume.
The unit of density derived from SI units is kilograms per cubic meter, kg/m3 or kg m-3.
More commonly, densities are given in g/mL (g mL-1) or g/cm3 (g cm-3 or g/cc).
Density is a characteristic property of pure substances so density can help identify a particular pure substance.
Since different substances have different densities, density can also be used to separate one substance from another.
In general, solids are more dense than liquids which are more dense than gases:
density of solid > density of liquid > density of gas
Step-by-step
Answer:
0.338 g/mL
Step-by-step explanation:
Density is the mass per unit volume of any object. It is calculated by dividing the mass of an object by its volume. This is:
ρ = m/V
ρ = 4.05 g / 12 mL
ρ = 0.3375 g/mL
ρ ≅ 0.338 g/mL

The graphical function representation of a function, represents the mapping of the domain of the function to the range of the function
The sum of the coordinates of the point is 7.25
The reason the above values are correct is as follows;
The given parameter is;
The point (9, 7) is on the graph y = f(x)
Required:
A point on the graph, 2·y = (f(2·x)/2) + 2
Solution:
Let x = 9/2, given that (9, 7), is on the graph, f(x), we get;
f(2·x) = f(2 × 9/2) = f(9) = 7
Therefore;
2·y = (f(2·x)/2) + 2 = (7/2) + 2) = 5.5
y = 5.5/2 = 2.75
y = 2.75
The coordinate of the point is (x, y) = (2.75, 9/2)
The sum of the coordinates of the point is 2.75 + 9/2 = 7.25

1. Find the lengths of the diagonals of rectangle QRST , Given that QS = 6X+3 and RT = 8X-1
2. If QR=9 , Find the length of TQ (Hint: There is a right angle in the Corner!)
Answer:
1. QS and RT= 15
2. Im not positive but I think it's TQ=18
Step-by-step explanation:
For question 1, you would do 6x+3=8x-1 and solve to get the result of x=2
Then you'd plug in 6 and get QS and RT=15
For the second one I am unsure because I wasn't positive how to solve but it seems like the side RQ might be 1/2 of TQ. Sorry if thats wrong I can try and help more if you need

These are special right triangles, a 45, 45, 90 and a 30, 60, 90 triangle. The formla for these triangles are shown in the picture below.
Now for the first one ]
Lets find Z first
Now this is a 45 special right triangle so we know the other side s 39 but the hypotenuse is n[tex]\sqrt{2}[/tex] (I’m using N becuase x and y is taken) So n is basically 39 (look at the image below) and just solve that. Now for x and y. We know its a 30, special right triangle. We know that 39 here is already the answer for N[tex]\sqrt{3}[/tex] so make an equation to find the n and you’ll get 27.58 for y. Now For x, its just doubled the y.
For the second one this is easier
We know that the x is (6) becuase its already in the radical number, now to find the hypotnuse, we double that and get 12. Now we know what y is becuase since the 2nd triangle is a 45/45/90, we know that 12 is y, the hypotnuse is just N[tex]\sqrt{2}[/tex] and we just plug in the n with 12 and solve it!
