Solve the simultaneous equations
-x + 5y = -7
x + y = – 5
x = 1
y= 0
y= -5-x
-x + 5(-5-x) = -7
-x -25-5x =-7
-x-5x = 25 -7
-6x= 18
x = -3
-3 +y = -5
y= -5 +3
=-2
-(-3) + 5(-2)
3 - 10 = -7
Answer:
y= -2, x= -3
Step-by-step explanation:
Firstly, substitute the x and y values:
-x + 5(0)= -7
x+ 0 = -5
second thing to check: DSA - different signs addition (positive x and -x)
-x+5y=-7 take away x+y=-5
6y= -12
y= -2
To find x: -x + 5(-2)= -7
-x= -7 + 10
x= -3

Approximately how many square inches of fabric were used to make the triangular flag? 15 square inches 76 square inches 186 square inches 215 square inches.
The area used to make the triangular flag is 15 square inches.
Given
Two of the sides are 8 in.
Lila made a triangular flag to cheer on her favorite sports team.
The perimeter of the flag is 20 inches.
What is Heron’s formula?Semi-perimeter is equal to the sum of all three sides of the triangle divided by 2.
Then,
The value of S is;
[tex]\rm S = \dfrac{20}{2}\\\\S =10[/tex]
Therefore,
The area used to make the triangular flag is;
[tex]\rm Area = \sqrt{s(s-a)(s-b)(s-c)} \\\\A rea= \sqrt { (10)(10-8)(10-8)(10-4) }\\\\Area = \sqrt{10 \times 2 \times 2\times 6}\\\\Area = \sqrt{240}\\\\Area = 15.49[/tex]
Hence, the area used to make the triangular flag is 15 square inches.

What are the benefits of creating and using functions in your code?.
How do I find the percent of a number?
Answer:
[tex]\frac{x}{100} =[/tex] the value you are solving for over total value.
Step-by-step explanation:
The way I learned it was like this:
Let's say you're trying to find the percent of red marbles there are in a pile. You have 24 red marbles and there are 48 in all. Set it up like so:
[tex]\frac{x}{100} =\frac{24}{48}[/tex]
x is over 100 because all percents are out of 100, and 24 is over 48 because that's the value you are trying to solve the percent for. Then cross-multiply.
[tex]\frac{x}{100} =\frac{24}{48}\\48(x)=24(100)\\48x=2400[/tex]
Then divide.
[tex]48x[/tex] ÷[tex]48x=2400[/tex] ÷ [tex]48[/tex]
[tex]x=50[/tex]
So the percentage is fifty.

During an experiment, the temperature of a mixture changes from 12 1/4°F to 15 3/5°F. What is the percent of increase in the temperature of the mixture?
The percentage increase is 21.4% increase
Given Data
Initial temperature = 12 1/4°F = 49/4 = 12.25°F
Final Temperature = 15 3/5°F = 78/5 = 15.6°F
We know that the expression for percentage increase is given as
Percent Increase = Increase/Final *100
Percent Increase = 15.6-12.25/15.6 *100
Percent Increase = 3.35/15.6 *100
Percent Increase = 0.214 *100
Percent Increase = 21.4%
Hence there is a 21.4% increase

Geometry: Help this makes no sense I don’t think there’s enough info needa find x so you have a triangle and you have a 90 degree angle and across that is the hypotenuse which is 18
Answer:
9√2
Step-by-step explanation:
a^2+b^2=c^2
a^2+b^2=18^2
a^2+b^2=324
324 ÷ 2 = 162
162 + 162 = 324 (on a 45 45 90 right triangle)
81 and 2 are factors of 162
square root of 162
√162 = √81 * 2 = 9√2

3x + 2y = 8
5x + 2y = 12
Step-by-step explanation:
to solve simultaneously
subtract the 1st equation from the 2nd.
5x + 2y = 12
3x + 2y = 8
5x - 3x + 2y - 2y = 12 - 8
2x = 4
x = 4 / 2

When creating a right triangle using 3 squares as seen in the online video, which sides create the right angle in the triangle?
When creating a right triangle using three squares, the sides of the two squares with the smallest areas will create the right angle in the triangle (see image attached below).
Creating a Right Triangle with Three SquaresThe right angle of a right triangle is formed by the two small legs of the right triangle that are perpendicular to each other.
Just like in the diagram attached below, the two squares with the smallest sides will form the right angle in the right triangle.
Therefore, we can conclude that when creating a right triangle using three squares, the sides of the two squares with the smallest areas will create the right angle in the triangle.
