Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
-5x + y = 1
9x - 2y = 4
Step 2: Rewrite Systems
-5x + y = 1
Add 5x on both sides: y = 5x + 1Step 3: Redefine Systems
y = 5x + 1
9x - 2y = 4
Step 4: Solve for x
Substitution
Substitute in y: 9x - 2(5x + 1) = 4Distribute -2: 9x - 10x - 2 = 4Combine like terms: -x - 2 = 4Isolate x term: -x = 6Isolate x: x = -6Step 5: Solve for y
Define equation: -5x + y = 1Substitute in x: -5(-6) + y = 1Multiply: 30 + y = 1Isolate y: y = -29Subtract 5y^2 + 3y + 11 from 4y^2 + 7 - 6y.
show steps please i know the answer but i need the steps :/
Answer:

Step-by-step explanation:
4y^2 - 5y^2= -y^2
7-11= -4
-6y + -3y= -9y
-y^2 -9y -4
if a circle has a circumference of 6/5 pi centimeters how long is its radius in centimeters
Answer:
r=3/5 centimeters
Step-by-step explanation:
C=(2)(pi)(r), where C= circumference and r=radius
6/5*pi=2*pi*r
divide both sides by 2pi
r=6/5pi*1/2pi
r=3/5

What are simultaneous equation ?"Simultaneous Equation is an essential Chapter in the Algebra branch of Mathematics. There are times when you come across two or more unknown quantities and two or more equations relating to them. These are called Simultaneous Equations. When you are asked to solve such equations, you must find values of the unknowns which satisfy all the given equations at the same time. They are Simultaneous Equations because the equations are solved at the same time. Simultaneous Equations need algebraic skills to find the values of letters within two or more equations."
Given, The equations
[tex]2x + 3y = 10[/tex] ----------- eq 1
[tex]4x - y = -1[/tex] ------------ eq 2
multiplying eq 1 by 2
[tex]4x + 6y = 20[/tex] ----------- eq 3
now subtracting eq 3 from eq 2
we get, [tex]7y = 21[/tex]
y = 3 and x = 1/2
Hence, the values of x and y = 1/2, 3 respectively.

Write the equation of this line in Point-Slope Form.
Answer:
y -3 = (-1/2)(x - 5)
Step-by-step explanation:
Slope of line: Notice that if we go from 7 to 5, the 'run' is -2 and the corresponding 'rise' from 2 to 3 is 1. Thus, the slope is m = -1/2.
Using m = -1/2 and the point (5, 3), we write the equation of this line in point-slope form as:
y -3 = (-1/2)(x - 5)

6 pounds of apples and 3 pounds of oranges cost 24 dollars.5 pounds of apples and 4 pounds of oranges cost 23 dollars. Set up a system of equations and solve to find out the cost for each pound of apples and each pound of oranges.
Answer:cost of each pound of apple= $3
And cost of each pound of orange =$2
Step-by-step explanation:
Step 1
Let cost of apples = x
And cost of Oranges =y
Let 6 pounds of apples and 3 pounds of oranges cost 24 dollars be represented as
6 x + 3y= 24----- equation 1
Also, Let 5 pounds of apples and 4 pounds of oranges cost 23 dollars be represented as
5x+ 4y= 23----- equation 2
Step 2
6 x + 3y= 24----- equation 1
5x+ 4y= 23----- equation 2
Using substitution method to solve the equation
6 x + 3y= 24
24-6x=3y
y= 24-6x/3 = 8-2x
Y= 8-2x
Substituting the value of y= 8-2x into equation 2
5x+ 4( 8-2x)= 23
5x+ 32 -8x= 23
32-23= 8x-5x
9=3x
x=9/3
x=3
Putting the value of x= 3 in equation 1 and solving to find y
6 x + 3y= 24
6(3) +3y= 24
18+3y=24
3y= 24-18
3y=6
y=6/3= 2
Therefore the cost of each pound of apple= $3
And cost of each pound of orange =$2

Chris's age is 17 more than one-fourth of Brian's age. How old is Chris if Brian is 27?
Answer:
23.75
Step-by-step explanation:
Given that:
Brian's age = 27
Age of Chris is 17 more than one - fourth of Brian's age.
To find:
Age of Chris = ?
Solution:
Let age of Chris = [tex]x[/tex]
One - fourth of Brian's age = [tex]\frac{27}{4}[/tex]
17 more than One - fourth of Brian's age = [tex]\frac{27}{4}[/tex] + 17
Therefore, we can write the equation as per question statement:
[tex]x = \frac{27}{4} + 17\\\Rightarrow x = 6.75+17\\\Rightarrow \bold{x = 23.75}[/tex]
Therefore, Chris is 23.75 years old if Brian is 27.

Amitas kitchen is rectangular with an area of 3 3 4 square meters the width of the kitchen is 1 1 2 meters what is the length in meters of amitas kitchen
Answer:
2 1/5 meters
Step-by-step explanation:
Given that:
Area of kitchen = 3 3/4
Width of kitchen = 1 1/2
Length = x
Recall : Area of rectangle = Length * width
Area of kitchen = length * width
3 3/4 = x * 1 1/2
15 / 4 = x * 3/2
x = 15/4 ÷ 3/2
x = 15/4 * 2/3
x = 30/12 = 2 6/30
x = 2 1/5

1.3181818...... as fraction units lowest term
Answer:
29/22
Step-by-step explanation:
Let x = 1.31818181818....
Then, 10x = 13.18181818..., and 1000x = 1318.18181818..... Subtracting the first equation from the second, we get that 990x = 1305. This means that x = 1305/990. In lowest terms, this is 29/22.
