Solve the following simultaneous equations 2x+5y=0 and 3x-4y=23
Answer:
x = 5, y = -2
Step-by-step explanation:
2x + 5y = 0 --- Equation 1
Equation 1×3: 6x + 15y = 0 --- Equation 2
3x - 4y = 23 --- Equation 3
Equation 3×2: 6x - 8y = 46 --- Equation 3
We will be eliminating 6x from Equation 2.
Equation 3-2: 6x - 8y - 6x - 15y = 46-0
-23y = 46
y = 46 ÷ -23
y = -2
Substitute y = -2 into Equation 1:
2x + 5y = 0
2x + 5(-2) = 0
2x + (-10) = 0
2x - 10 = 0
2x = 10
x = 10 ÷ 2
x = 5

The sum of a three digit number and a one digit number is 731 the product of the number is 2908 what are the numbers
The one digit number is 4 and three digit number is 727.
Let us consider the one digit number be a and three digit number be b. Given that their sum is equal to 731.
a + b = 731 : equation 1
Also, their product is equal to 2908.
a × b = 2908 : equation 2
Now, from equation 1, the value of b is
b = 731 - a : equation 3
Putting the value of b in equation 2, we get
a (731 - a) = 2908
731a - a² = 2908
a² - 731a + 2908 = a
Using middle term splitting, the equation can be written as
a² - 727a - 4a + 2908 = 0
a(a - 727) - 4(a - 727) = 0
a - 4 = 0 and a - 727 = 0
a = 4, 727
Now, putting the value of a in equation 3, we get
b = 731 - 4 and 731 - 727
b = 727, 4
Thus, the one digit number is 4 and three digit number is 727.

Mrs. Haley had 5/7 of a liter of salt water. She used 1/2 of a liter for an experiment. How much salt water does Mrs. Haley have left?
Mrs. Haley had
liters of salt water left.
Answer:
3/14 of a liter of salt
Step-by-step explanation:
Step one:
given
tot amount of salt= 5/7 of a liter of salt
that is 1*5/7= 5/7 liters
She used 1/2 of a liter for an experiment
Required:
the remaining amount of salt
Step two:
we are going to subtract the salt used for the experiment from the total
= 5/7-1/2
= 10-7/14
= 3/14
The remainder is 3/14 of a liter of salt

time for each batch is 12 minutes.
* matched pairs experimental design
O completely randomized experimental design
randomized block experimental design
none (observational study only)
Answer:
C.) completely randomized experimental design
Step-by-step explanation:
Edge 2020
The experimental design used by Betty is completely randomized experimental design. Hence, option A is correct.
What is an experiment?A process used to confirm or deny a theory, as well as assess the effectiveness or possibility of something that has never been performed before, is called an investigation.
By showing what happens when a particular element is modified, experiments shed light on causation relationships. Experiments have a wide range of objectives and sizes, but always depend on a repeatable process and a logical examination of the outcomes. Additionally, there are experiments conducted in nature.
As Betty is wants to bake a perfect cookie, and she has enough batter. She is testing to bake the batter at different temperatures to see that what is the ideal temperature to make perfect cookies. So, this is completely randomized experimental design.

Solve simultaneous equation
2x-y=7
x*2+y*2=49
(x, y) = (0, -7) and ((28/5 , 21/5)) , as found by solving the system of linear equations.
What is a system of linear equations?
A system of linear equations is a set of two or more linear equations. Linear equations refer to the equations that involve two or more variables in the form of "ax + b".
Given: 2x - y = 7x² + y² = 49
to find: Values of x and y.
Finding:
Solving the system of two linear equations, by deriving the value of one variable from an equation and substituting it in the other equation and solving for the two variables.
eqn1 2x - y = 7
y = 2x - 7
eqn2 x² + y² = 49O
substituting the value of y from eqn1,
we get: x² + (2x - 7)² = 49
x² + 4x² + 49 - 28x = 49
5x² -28x = 0
x ( 5x - 28) = 0
x = 0, x = 28/5
For x = 0, y = -7 (in eqn1)=>
(x, y) = (0, 7)
For x = 28/5
y = 2(28/5) - 7
= (56 - 35) / 5
= 21 / 5
(x,y) = (28/5 , 21/5)
Hence, (x, y) = (0, -7) and (28/5 , 21/5), as found by solving the system of linear equations.

jenny has 8 stamp books that each contain 42 pages. each page in her books contains 6 stamps. jenny decides to reorganize her stamp books such that each page contains 10 stamps. this will give her more space to collect stamps without having to buy new books. under her new system, jenny fills up 4 complete books, still with 42 pages per book. her fifth book now contains 33 pages filled with 10 stamps per page and 1 last page with the remaining stamps. how many stamps are on that last page?
There are 6 stamps on the last page.
The number of stamp books is 8.The number of pages in each stamp book is 42.The number of stamps on each page is 6.The total number of stamps is 8*42*6.The total number of stamps is 2016.After the reorganization of the stamps,The number of completely filled stamp books is 4.The number of completely filled pages is 42*4 + 33.The updated number of stamps on each page is 10.The number of stamps on the last page is equal to the total number of stamps minus the number of stamps on completely filled pages.The number of stamps on the last page is 2016 - [(4*42 + 33)*10].The number of stamps on the last page is 2016 - [(168 + 33)*10].The number of stamps on the last page is 2016 - (201*10).The number of stamps on the last page is 2016 - 2010.The number of stamps on the last page is 6.To learn more about stamps, visit :
