Solve the simultaneous equations
5x + 3y = 41
2x + 3y = 20
Do not use trial and improvement
Answers
2x + 3y = 20
Solve 3y
-> 3y = 41 - 5x
Substitute
2x + 41 - 5x = 20
-3x = 20 - 41
= -21
x= 7
Substitute
2x + 3y = 14 + 3y = 20
3y = 6
y = 2
=> x=7, y=2
The solution to the system of equation is (7, 2)
Using the simultaneous equation:
5x + 3y = 41
2x + 3y = 20
using elimination method
Subtract equation 1 from 2 to have:
5x - 2x = 41 - 20
3x = 21
x = 21/3
x = 7
Substitute x = 7 into equation 1 to get y
5x + 3y = 41
5(7) + 3y = 41
35 + 3y = 41
5y = 41 - 35
3y = 6
y = 6/3
y = 2
Hence the solution to the system of equation is (7, 2)

Hiro painted his room. After 3 hours of painting at a rate of 8 square meters per hour, he had 28 square meters left to paint.
Let y represent the area (in square meters) left to paint after x hours.
Which of the following information about the graph of the relationship is given?
Answers
Answer:
Slope and a point that is not an intercept
Let
x ----> the time in hours
y ----> the area (in square meters) left to paint
we know that
Hiro paint at a rate of 8 square meters per hour
The rate is equal to the slope of the linear equation
we have the point (3, 28) ---> After 3 hours of painting, he had 28 square meters left to paint.
therefore

Noah and Lin are marketing paper cones to hold popcorn to hand out at parent math night. They want the cones to hold 9 cubic inches of popcorn. What are two different possible values for height h and radius r for the cones?
if h=3, then r=
if r=2, then h=
Answers
Answer: r = 1.69 inches
h = 2.15 inches
Step-by-step explanation: Volume of a solid is the amount of space contained within a solid.
Volume of a cone is directly proportional to radius and height:
[tex]V=\frac{1}{3}\pi r^{2}h[/tex]
They want the cones to hold the same volume of 9 cubic inches.
If height is 3:
[tex]9=\frac{1}{3}\pi r^{2}3[/tex]
[tex]\pi r^{2}=9[/tex]
[tex]r^{2}=2.864[/tex]
r = 1.69 inches
When height is 3, radius is 1.69 inches for a cone to have 9 cubic inches of volume.
If radius is 2:
[tex]9=\frac{1}{3}\pi (2)^{2}h[/tex]
[tex]h=\frac{9(3)}{4 \pi}[/tex]
h = 2.15 inches
If radius is 2 inches, height of the cone is 2.15 inches.

Answer: The length of the hypotenuse (c) is 5
Step-by-step explanation:
Use the Pythagorean Theorem
a² + b² = c²
a & b are the legs (b is the base)
c = hypotenuse
a = 4
b = 3
a² + b² = c²
4² + 3² = c²
16 + 9 = c²
25 = c²
√c² = √25
c = 5
3^2 +4^2= c^2

You measure 3 inches between your house and the movie theater. How many miles is in from your house to the movie theater?
Answers
Answer:
4.734 * 10^-5 miles
Step-by-step explanation:
Given that:
Distance between House to movie theater = 3 inches
Expressing the distance in miles :
Converting inch to miles
1 inch = 1.578 * 10^-5 miles
3 inches = (3 * 1.578*10^-5)
3 inches = 4.734 * 10^-5 miles

Answer:
D I dont know if im right though
Step-by-step explanation:
The system of equations are same and graphs of the equations are the same line because the equations have the same slope and same y-intercept. The system has infinitely many solutions.
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
The first equation is -3x + 3y = 12 be equation (1)
y = x + 4 be equation (2)
Adding 3x on both sides , we get
3y = 3x + 12
Divide by 3 on both sides , we get
y = x + 4 be equation (3)
So , the equation ( 2 ) is same as equation ( 3 )
Now , the slope of the equation is m = 1 and the y intercept is b = 4
Hence , the equations have infinite solutions

Mary bought 5 pairs of gloves and 2 hats for $95. Mary received a text from her friend Joanna ask her to buy 4 pairs of gloves and a hat. Mary told Joanna that the cost was $70. How much does each pair of gloves cost? How much does the hat cost?
Answers
Answer: Each pair of gloves costs $15 and each pair of hat costs $10.
Step-by-step explanation:
Let x = Cost per pair of gloves
y= Cost per hat.
As per given, we have
[tex]5x+2y=95 \ \ \ \ (i)\\4x+y=70\ \ \ \ \ (ii)[/tex]
Multiply (ii) by 2 , we get
[tex]8x+2y=140\ \ \ \ (iv)[/tex]
Eliminate (i) from (iv), we get
[tex]3x=45\\x=15[/tex]
Put this in (ii), we get
[tex]4(15)+y=70\\60+y=70\\y=10[/tex]
Hence, each pair of gloves costs $15 and each pair of hat costs $10.

1st one x=245°
2nd one x= 250
Step-by-step explanation:
hope its correct
hope u find it helpful
Answer:
x = 245 and x = 20
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5 , then
sum = 180° × 3 = 540°
Sum the interior angles and equate to 540
25 + 112 + 100 + 58 + x = 540
295 + x = 540 ( subtract 295 from both sides )
x = 245
---------------------------------------------------------------
5x + 2 + 3x + 5 + 8x + 8 + 4x + 15 + 5x + 10 = 540
25x + 40 = 540 ( subtract 40 from both sides )
25x = 500 ( divide both sides by 25 )
x = 20
