Answer:
x = 18 and x = 36
Step-by-step explanation:
let unknown value is x
6:x = 1:3
product of means = product of extremes
6*3 = 1 *x
18 = x
x:30=8:5
product of means = product of extremes
5x=180
x=180/5
x=36

Which of the following shows the correct sums that would be found when clustering is used to find the answer to the problem 34 x 12?
340 + 68 = 408
340 + 34 = 374
340 + 68 = 398
300 + 8 = 308
The first option is correct.
The calculation is as follows:if we multiply the 34 and 12 so it comes 408
And according to first option, it we add 340 and 68 so it comes 408.

Rita makes and sells necklaces. The materials to make each necklace cost $2.75. Last week she made 8 necklaces and wants to make a total profit of $78. Using the equation 8 (x + 2.75) = 78, Rita determined that she needs to sell each necklace for $7 to make a total profit of $78. Which error did Rita make?
Although she has the correct equation, she needs to sell each necklace for $12.50.
Although she has the correct solution, she should have used the equation 8 (x minus 2.75) = 78.
The equation should be 8 (x minus 2.75) = 78, and she needs to sell each necklace for $12.50.
The equation should be StartFraction 1 over 8 EndFraction (x minus 2.75) = 78, and she needs to sell each necklace for $75.25.

Answer:
The equation should be 8 (x minus 2.75) = 78, and she needs to sell each necklace for $12.50.
Step-by-step explanation:
The contribution margin of each necklace is the difference between its selling price (x) and its cost (2.75). Then the total profit from 8 necklaces would be ...
8(x -2.75)
If Rita wants that profit to be $78, then she needs to solve the equation ...
8(x -2.75) = 78 . . . . correct equation
The solution is ...
x -2.75 = 9.75 . . . . divide by 8
x = 12.50 . . . . . . . . add 2.75
She needs to sell each necklace for $12.50.

Sean's father decided that the number of hours Sean should study daily is equal to the equation y + 4 16. where y is the
number of study hours and z is the number of relaxation hours. Sesn's mother believes that the number of hours Sean should study
dally should be equal to the equation 2y + 5z = 32. Sean's parents have decided to use both equations to determine the number
of hours Sean should study and relax What is an equivalent equation to the addition of Sean's mother's equation and Sean's father's
equation? Select all that apply.
Answer and explanation:
We add both equations to get a simultaneous equation
y+4z=16
2y+5z=32
We solve the equations using elimination method:
Multiply equation 1 by 5 and equation 2 by 4 to cancel out z
5y+20z=80
8y+20z=160
-3y=-80
Y=26.7
Substitute y=26.7 in equation 1
26.7+4z=16
4z=16-26.7
z= -2.67
y+z=26.7+(-2.67)= 24.03

Answer:
y+2=6x+2
Step-by-step explanation:
[tex]y+2=2(3x+1)\\y+2=6x+2\\y=6x+2-2\\y=6x[/tex]
Since the exponent/degree of x and y both the variables are 1 the equation is linear and y=6x represents a proportional relationship between x and y

Anybody Know This. ?
Answer: 4 feet
Step-by-step explanation:
In order to determine the length of side, we need to use what is called the Pythagorean theorem, which states: a² + b² = c² The a and b in this equation are both of the sides of the triangle that we call legs. (I have attached a picture for reference if you do not know what sides I am referring to). The c in this equation refers to the hypotenuse of the triangle. (Again, please refer to the attached photo).
So now, we need to plug in the information we already know into this equation. The height of the ramp will be our a and the distance from the box will be our b. We can see that the hypotenuse (c) is labeled as 5, so we can fill in that information in our equation.
a²+b²=5² (simplify by squaring the 5)
a²+b²=25
Next, we know that the height of the box is 3 feet, which let's us know that our a is 3. Let's plug this new information in.
3²+b²=25 (simplify by squaring the 3)
9+b²=25 (simplify by substracting the 9 from both sides)
25 - 9 = 16b²=16
Hey! Now our equation looks much simpler! Now, all we need to do it square root both of the sides in order to get b by its self.
b²=16
√b² = b
√16 = 4
Final answer: b = 4
I truly hoped this explanation helped! If you feel you still need a bit of help, David May explains the Pythagorean theorem very well in his video titled, "Find The Hypotenuse Using Pythagorean Theorem | Dave May Teaches" if you would like to check it out. Take care! :)
Calculate the simple interest on $600 left in account that pays 7% annual interest for 8 years.
Answer:
S = $336
Step-by-step explanation:
Given the following data;
Principal, P = $600
Rate, R = 7
Time, T = 8 years
To find the simple interest?
Mathematically, it is given by the formula;
Simple interest, S = (P*R*T)/100
Substituting into the equation, we have;
S = (600*7*8)/100
Simplifying the equation, we have;
S = 6*7*8
S = $336
