X=1-y, 6x+5y=11 using substitution method
Answer:
x=6 y=-5
Step-by-step explanation:
6x+5y=11
X=1-y
6x=6(1-y)
6x=6-6y
6-6y+5y=11
6-y=11
y=-5
x=1-y
x=1-(-5)
x=6
so,
x=6
y=-5
Answer:
[tex]y = ( - 5) \\ x = 6[/tex]
Step-by-step explanation:
[tex]x = 1 - y \\ 6x + 5y = 11 \\ \\ \\ 6(1 - y) + 5y = 11 \\ 6 - 6y + 5y = 11 \\ - 6y + 5y = 11 - 6 \\ - y = 5 \\ y = - 5[/tex]
[tex]x = 1 - y \\ x = 1 - ( - 5) \\ x = 1 + 5 \\ x = 6[/tex]
Let's check whether the answer is correct.
[tex]6x + 5y = 11 \\ 6 \times 6 + 5 \times ( - 5) = 11 \\ 36 - 25 = 11 \\ 11 = 11[/tex]

3x + 4 = 13 solve for X
Answer:
x = 3
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Do the opposite of PEMDAS.
First, subtract 4 from both sides:
3x + 4 (-4) = 13 (-4)
3x = 13 - 4
3x = 9
Next, divide 3 from both sides:
(3x)/3 = (9)/3
x = 9/3
x = 3

Find the area of each sector. Photo attached
Answer:
Area of sector: 48π in^2; Option D
Step-by-step explanation:
~ We can see that the bolded portion of the circle must be the the sector that we need to compute the area of... ~
Let us plan out this problem. If we were to find the area of the circle provided a radius of 12 inches, we could create a proportionality between the degree of the sector, and the degree of the circle ( 360 ) and the area of the sector and the area of the circle.
1. To calculate the area of this circle, let us apply the formula πr^2, such that r is 12 inches ( and let us keep π in terms of π ) ⇒ π * ( 12 )^2 ⇒ 144 * π ⇒ Area of Circle: 144π
2. Let us see this as a proportionality:
Degree of sector/ Degree of circle = Area of sector/ Area of circle
3. Now let us say x ⇒ Area of the sector. Substitute values into this formula, and solve for x through algebra:
120 / 360 = x / 144π,
120 * 144π = 360 * x,
17,280π = 360 * x,
x = 17,280π / 360,
Area of sector: 48π in^2

A baseball team played 82 games. The team won 7 more than twice as many games as it lost. The equation l+2l+7=82 models this relationship, where l is the number of games lost. How many games did the team lose? How many games did the team win?
Answer:
The team lost 25 games and won 57.
Step-by-step explanation:
I am going to say what:
w is the number of games won.
As the problem states, l is the number of games lost.
The team won 7 more than twice as many games as it lost.
This means that [tex]w = 2l + 7[/tex]
A baseball team played 82 games.
This means that:
[tex]w + l = 82[/tex]
[tex]2l + 7 + l = 82[/tex]
[tex]3l = 75[/tex]
[tex]l = \frac{75}{3}[/tex]
[tex]l = 25[/tex]
And
[tex]w = 2l + 7 = 2*25 + 7 = 57[/tex]
The team lost 25 games and won 57.
Nadia drew a design for a copper wire sculpture as shown above.She plans to make a wire frame that includes the perimeter of the square and the circumference of the circle.She has 5 feet of copper wire.Does she have enough wire for the sculpture?
Answer:
She does not have enough wire.
Step-by-step explanation:
The complete question included a design for her sculpture. It is a circle inscribe in a square and the length of the square is 9 inches. The picture above describe the design.
She has in possession a 5 ft of copper to construct a circle inscribe in a square.
The square is 9 inch length.
Perimeter of the square = 4L
where
L = length
Perimeter of the square = 4 × 9
Perimeter of the square = 36 inches
Circumference of a circle = 2πr
r = diameter/2 = 9/2 = 4.5 inches
Circumference of a circle = 2 × π × 4.5
Circumference of a circle = 2 × 4.5 × 3.14
Circumference of a circle = 9 × 3.14
Circumference of a circle = 28.26 inches.
The sculpture will consume 36 inches for the square and 28.26 inches for the circle. The total length for the sculpture will be 36 + 28.26 = 64.26 inches.
She has 5 ft copper for the sculpture . Let us covert the inches to ft to know if the copper wire is enough.
12 inches = 1 foot
64.26 inches = ?
cross multiply
wire required for the sculpture = 64.26/12
wire required for the sculpture = 5.355 ft
She does not have enough wire.
Answer:
No she does not have enough

The manager of a store increases the price of the bathing suits by 7%. Let t be the original price of a bathing suit. The new price is t + 0.07t. A. Find an expression equivalent to t + 0.07t.
Answer:
[tex]t+0.07t=t(1+0.07)=t(1.07)=1.07t[/tex]
Step-by-step explanation:
There are a couple of equivalent expressions to the function [tex]t+0.07t[/tex]. For example:
[tex]t+0.07t[/tex]
Factor:
[tex]t+0.07t=t(1+0.07)[/tex]
If you add the terms inside the parentheses:
[tex]t(1+0.07)=t(1.07)[/tex]
Basically you can add the like terms from the start and get the same result.
[tex]t+0.07t=1.07t[/tex]
Therefore:
[tex]t+0.07t=t(1+0.07)=t(1.07)=1.07t[/tex]
What are the solutions of the equation (x – 3)2 + 2(x – 3) -8 = 0? Use u substitution to solve.
x = -5 and x = 1
x = -1 and x = 5
x= -1 and x = -7
x = 1 and x = 7
Answer:
x = -1 and x = 5
Step-by-step explanation:
What are the solutions of the equation (x – 3)² + 2(x – 3) -8 = 0? Use u substitution to solve.
(x – 3)² + 2(x – 3) -8 = 0 -------------------------------------------------------(1)
To solve this problem, we will follow the steps below;
let u = x-3
we will replace x-3 by u in the given equation:
(x – 3)² + 2(x – 3) -8 = 0
u² + 2u -8 = 0 ----------------------------------------------------------- --------------(2)
We will now solve the above quadratic equation
find two numbers such that its product gives -8 and its sum gives 2
The two numbers are 4 and -2
That is; 4×-2 = -8 and 4+(-2) = 2
we will replace 2u by (4u -2u) in equation (2)
u² + 2u -8 = 0
u² + 4u - 2u -8 = 0
u(u+4) -2(u+4) = 0
(u+4)(u-2) = 0
Either u + 4 = 0
u = -4
or
u-2 = 0
u = 2
Either u = -4 or u = 2
But u = x-3
x = u +3
when u = -4
x = u + 3
x = -4 + 3
x=-1
when u = 2
x = u + 3
x = 2 + 3
x=5
Therefore, x = -1 and x =5

Answer:
$9257.5
Step-by-step explanation:
plug into the equation known variables
Answer:
2257.50
Step-by-step explanation:
B=p(1+r)^t
p= principal amount= $7000 in the saving account
r= interest rate= 15%= .15
t- number of years = 2
B= 7000(1+.15)^2
B= 7000(1.15)^2
B= 7000(1.15)(1.15)
B= 9257.50
She has a total of 927.50 dollars in the account after two years. To find out how much of that is interest we take the Balance and subtract what she invested.
B-p= 9257.50-7000= 2257.50 earned in interest.

Answer:
(-6,-2)
Step-by-step explanation:
Hello! Lets get started!
By looking at this problem, we see that both equations equal 2. This makes this problem much easier!
While there are a few methods you could solve this, I will use substitution. First, I need to find what x is in terms of y!
There are many different ways you could do this, here are two:
-x = 2-2y ==> x = -2+2y
-x + 2y = -3x + 8y ==> 2x = 6y ==> x = 3y
For this problem, I am going to use the second answer, x = 3y, as it is simpler!
We need to substitute 3y in for x in either equation; I am going to use the first equation, -x + 2y = 2.
-3y + 2y = 2
-y = 2
y = -2
Now, lets solve for x!
-x + 2(-2) = 2
-x - 4 = 2
-x = 6
x = -6
After plugging the answers into both equations, we see that they are in fact true!
Therefor, our final answer is (-6, -2)
