Answer:
6 and 3
Step-by-step explanation:
let x and y be the 2 numbers with x > y , then
2x + 3y = 21 → (1)
x - y = 3 → (2)
Multiplying (2) by 3 and adding the result to (1) will eliminate y
3x - 3y = 9 → (3)
Add (1) and (3) term by term to eliminate y
5x = 30 ( divide both sides by 5 )
x = 6
Substitute x = 6 into either of the 2 equations and solve for y
Substituting into (1)
2(6) + 3y = 21
12 + 3y = 21 ( subtract 12 from both sides )
3y = 9 ( divide both sides by 3 )
y = 3
The 2 numbers are 6 and 3

Answer:
M1=35, M2=77, M3=49, M4=77, M5=62, M6=28
Step-by-step explanatio
Answer:
Angle 1) 35
Angle 2) 77
Angle 3) 49
Angle 4) 77
Angle 5) 62
Angle 6) 28
Step-by-step explanation:
Start with angle 3)
You have 2 angles for this one already, 90 and 41
All angles in a triangle have the sum of 180, therefore
Angle 3 = 180 - 90 - 41
Angle 3 = 49
Next is Angle 6)
You have Angle 3 and 103
Angle 6 = 180 - 49 - 103
Angle 6 = 28
Now Angle 2)
Angle 2 is on the same line as 103 and are supplementary, the sum is 180
Angle 2 = 180 - 103
Angle 2 = 77
Angle 4)
2 and 4 are vertical opposites with the same measurement, so 77
Angle 1)
Using Angles 1 and 2 and 68, they have a sum of 180
Angle 1 = 180 - 77 - 68
Angle 1 = 35
Angle 5)
Now with Angle 4 and 41 thats given, Angle 5 is
180 - 77 - 41 = 62

There are 15 plates in the kitchen cabinet. The diameter of each plate is either 9 inches or 12 inches. The diameter of all 15 plates combined is 150 inches.
Which system of equations can be used to find the number of 9-inch plates, x, and the number of 12-inch plates, y, that are in the cabinet?
Answer:
Step-by-step explanation:
The important thing to remember here is that the number of plates is a different equation from the one that uses the diameter of the plates. The number of plates will make up one equation; the diameter of the plates will make up the other equation. As far as the number of plates go, we have 15 total. Let's call the 9" plates x and the 12" plates y according to the instruction given. If we have a mixture of 9 and 12 inch plates and we have a total of 15 plates, the first equation regarding the number of plates is
x + y = 15
Now on to the diameters. The 9" plates are x's and the 12" plates are y's and the inches refer to the diameter, of which the total is 150". Therefore, the second equation regarding the diameter of the plates is
9x + 12y = 150
Those 2 equations make up the system. It doesn't say you have to solve it, but if you did, you would find that there are 10 9" plates and 5 12" plates in the cabinet.

y is inversely proportional to x.
When x=9, y = 8.
Find y when x= 6.
Answer:
y = 12 when x = 6
Step-by-step explanation:
The equation for inverse proportion is
xy = k where k is a constant
Let x = 9 and y = 8
9*8 = k
72 = k
The equation is xy = 72
Let x=6
6*y = 72
Divide each side by 6
6y/6 = 72/6
y =12

A rectangular-shaped school courtyardhas a length of 280 feet and a width of150 feet wide. What is the approximatelength of a diagonal of the courtyard tothe nearest tenth?
Answer:
317.6 feet
Step-by-step explanation:
the length of the diagonal can be determined using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
280² + 150²
= 78,400 + 22,500
= 100,900
take the square root of 100,900
= 317.648 feet
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
317.6 to the nearest tenth
Solve graphically: 2x - y = 7 and x - 2y = 5.
Answer:
(3, - 1)
Step-by-step explanation:
We want to solve the system of equations:
2*x - y = 7
x - 2*y = 5
graphically.
To do it, we need to graph both lines, it will be easier if we rewrite both lines in a more general way, like in the slope-intercept form:
y = -7 + 2*x
y = -(5/2) + x/2
Now, a solution of the system is a point (x, y) such that the point is a solution to both equations, then, when we graph the lines, as that point belongs to both equations, we should see that both lines pass through that point.
Then to find the solution of the system, we just need to graph the lines and find the point where the lines intersect.
Below, you can see a graph of the lines, and is easy to see that the lines do intersect at the point (3, - 1)

A parallelogram has a base of 9 km and a height of 5 km. A triangle has a base of 6 km and a height of 3 km. How many times greater is the area of the triangle?
Answer:
Parallelogram has greater area.
Step-by-step explanation:
Given:
Base of parallelogram = 9 km
Height of parallelogram = 5 km
Base of triangle = 6 km
Height of triangle = 3 km
Find:
Greater area
Computation:
Area of parallelogram = Base x Height
Area of parallelogram = 9 x 5
Area of parallelogram = 45 km²
Area of triangle = (1/2)(b)(h)
Area of triangle = (1/2)(6)(3)
Area of triangle = (1/2)(18)
Area of triangle = 9 km²
Parallelogram has greater area.

Step-by-step explanation:
Is the statement true or false?
If x = 6, then x can
only be equal to 6.
True
False
Copyright © 2003 - 2021 Asellus Corporation
The statement "If |x| = 6, then x can only be equal to 6" is false.
The absolute value of a number represents its distance from zero on the number line.
The expression |x| = 6 means that the distance of x from zero is 6. Therefore, x can be either positive or negative 6.
In this case, x can be either 6 or -6 because both numbers have an absolute value of 6.
Hence, x is not limited to being equal to only 6.
