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.

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

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total amount of money in Mary's account be = $ 120
The amount of money that gets deducted for each week = $ 5
Total number of weeks elapsed = 15 weeks
So , the equation will be
Total amount deducted after 15 weeks = number of weeks elapsed x amount of money that gets deducted for each week
Total amount deducted after 15 weeks = 15 x 5
= $ 75
Therefore , the equation will be
The amount left in Mary's account = total amount of money in Mary's account - Total amount deducted after 15 weeks
The amount left in Mary's account = 120 - 75
= $ 45
Hence , The amount of money Mary has left in her account is $ 45

PLEASE HELP- A triangle has vertices A(0, 0), B (9, 4), and C(–2, 10). What are the coordinates of the triangle after a dilation with a scale factor of 1/2 ?
Answers
Basically multiply the x and y coordinates of each point by 1/2
For example, I'll do C which is ( -2 , 10 )
-2 * 1/2 = -1 and 1/2 * 10 = 5
The new coordinate is ( -1 , 5 )

A truck that is 10 ft. by 12 ft. by 8 ft. carries cube shaped boxes that have a
length of 1.5 ft. How many of these boxes can this truck hold?
Answers
Answer:
284.4
Step-by-step explanation:
Divide all numbers by 1.5. example: (10)1.5(12)1.5(81.5= 284.444444 but I rounded it to 284. You're welcome
284 boxes in the shape of the cubes can be fitted in the truck.
If a truck is fitted fully with the cubes, volume of the truck will be equal to the volume of cubes to be fitted.
Dimensions of the truck given in the question,
Length = 10 feet, width = 12 feet and height = 8 feetSince, volume of a cuboid (shape of a truck) is given by the expression,
Volume = Length × Width × Height
Therefore, volume of the truck = 10 × 12 × 8
= 960 feet³
Volume of a cube is given by the expression,
Volume = (side)³
Therefore, volume of the cube with side length 1.5 feet will be,
Volume of a cube = (1.5)³
= 3.375 cubic feet
Let the number of cubes fitted in the truck = x
Therefore, volume of 'x' cubes = (3.375x) feet³
Since, volume of the truck = Volume of the cubes fitted
3.375x = 960
x = [tex]\frac{960}{3.375}[/tex]
x = 284.44
x ≈ 284
Therefore, 284 boxes in the shape of the cubes can be fitted in the truck.

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.
