Answer:
x=3,y=6
Step-by-step explanation:
2x−y=0
3x−2y=−3
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
2x−y=0,3x−2y=−3
To make 2x and 3x equal, multiply all terms on each side of the first equation by 3 and all terms on each side of the second by 2.
3×2x+3(−1)y=0,2×3x+2(−2)y=2(−3)
Simplify.
6x−3y=0,6x−4y=−6
Subtract 6x−4y=−6 from 6x−3y=0 by subtracting like terms on each side of the equal sign.
6x−6x−3y+4y=6
Add 6x to −6x. Terms 6x and −6x cancel out, leaving an equation with only one variable that can be solved.
−3y+4y=6
Add −3y to 4y.
y=6
Substitute 6 for y in 3x−2y=−3. Because the resulting equation contains only one variable, you can solve for x directly.
3x−2×6=−3
Multiply −2 times 6.
3x−12=−3
Add 12 to both sides of the equation.
3x=9
Divide both sides by 3.
x=3
The system is now solved.
x=3,y=6

A shoe box in the shape of a rectangular prism measures 12in by 7in by 4in. What is the surface area of the shoe box?
Answer:
320 sq in
Step-by-step explanation:
SA(rect prism) = 2(lw)+2(wh)+2(lh)
= 2(12·7)+2(7·4)+2(12·4)
= 2(84)+2(28)+2(48)
= 168+56+96

The radius r of the circle is 4.4 yd .
What is sector of circle?A circular sector, also known as circle sector or disk sector, is the portion of a disk enclosed by two radii and an arc, where the smaller area is known as the minor sector and the larger being the major sector.
What is length of arc?For a circle, the arc length formula is θ times the radius of a circle.
Arc Length = 2 π r (θ/360°)
where,
r = radius of circle
θ = angle of Sector
According to the question
Arc Length of circle = 16.3 yd
Angle of sector= 240°
By using arc length formula
Arc Length = 2 π r (θ/360°)
substituting the value
16.3 = 2π r (240°/360°)
16.3 = 2π r * [tex]\frac{2}{3}[/tex]
16.3 * 3 = 4π r
54.9 = 4π r
As π = [tex]\frac{22}{7}[/tex]
54.9 = 4 * [tex]\frac{22}{7}[/tex] r
54.9 * 7 = 88 r
384.3 = 88 r
r = 4.4 yd
Hence, The radius r of the circle is 4.4 yd .

Answer:
Half of 4 is 2
2^2 = 4
4 x 3.14 = 12.56, 12.56 divided by 2 = 6.28
10 + 2 = 12
12 x 4 = 48, 48 x 1/2 (basically just dividing by 2) = 24
Add the given areas:
24 + 6.28 = 30.28 m^2

The perimeter of a rectangular garden is 36 1/2 feet. One side of the garden is 9 feet long. What is the area, in square feet, of the garden?
Group of answer choices
81 1/4
83 1/4
85 1/2
85 9/16
Answer:
83 1/4 sq ft
Step-by-step explanation:
let x = length or width of two identical unknown sides
2(9) + 2x = 36 1/2
18 + 2x = 36 1/2
2x = 18 1/2
x = 37/2 ÷ 2 = 37/4 or 9 1/4
therefore, multiply 9 by 9 1/4
Area is: 9/1 x 37/4 = 333/4 = 83 1/4

Two angles are a linear pair. Their measures are represented by x+10 and 3x+10. What are the measures of the angles
Answer:
50° and 130°
Step-by-step explanation:
Linear pair of angles are supplementary, which means their sum is 180
x + 10 + 3x + 10 = 180
4x + 20 = 180
4x = 160
x = 40
x + 10 = 40 + 10 = 50°
3x + 10 = 3(40) + 10 = 120 + 10 = 130°
