Answer:
x = -7
y = 9
Step-by-step explanation:
x + y = 2
x - y = -16
substitute '2-x' for 'y'
x - (2-x) = -16
x - 2 + x = -16
2x - 2 = -16
2x = -14
x = -7
-7 + y = 2
y = 9

What is the value of a in the equation 0.75 (a - 2) = 5.25
Answer:
a must be 9
Step-by-step explanation:
Divide both sides of the given equation by 0.75, to isolate (a - 2):
a - 2 = 5.25/0.75 = 7
Then a - 2 = 7, and so a must be 9.

Pentagon CDEFG is shown on the coordinate plane. Pentagon CDEFG is translated 7 units up and 5 units left, resulting in C'D'E'F'G' (not shown.) Select from the drop-down menus to correctly complete each sentence.
The length of line segment FG is greater,than,less than,equal to.
The perimeter of pentagon CDEFG is less then greater than or equal to the perimeter of pentagon C'D'E'F'G.
Answer:
The length of line segment FG is equal to the length of F'G'
The perimeter of pentagon CDEFG is equal to the perimeter of pentagon C'D'E'F'G.
Step-by-step explanation:
Given
CDEFG and C'D'E'F'G
Translation: 7 units up and 5 units left
Solving (a): Segment FG and F'G'
When a shape is translated, the resulting image will have the same lengths as the original image (i.e, translation does not change measurements)
Hence:
[tex]FG = F'G'[/tex]
Solving (b): Perimeter CDEFG and C'D'EF'G'
In (a), we established that lengths do not change during translation;
Hence:
The perimeter of the CDEFG and C'D'EF'G' will remain the same
A rectangular bakery is 37 feet wide and 70 feet long. What is its perimeter?
Answer:
214 ft
Step-by-step explanation:
P = 2(L + W)
P = 2(70 + 37)
P = 2(107)
P = 214 ft

represent 3/4 and 8/9 on a number line
Answer:
Step-by-step explanation:
3/4 and 8/9 both lie between 0 and 1. Their LCD is 36.
Thus, 3/4 = 27/36 and 8/9 = 32/36.
Dividing the number line between 0 and 1 into 36 equal lengths, plot a dot at the 27th such mark and then another dot at the 32nd mark.
This clearly shows that 32/36 is larger than 27/36.

Mr. Hawkins is covering a wall with wallpaper. The room measures 14 feet by 12 feet in a rectangular shape. Each square foot or wallpaper costs $2.90. What is the cost of adding wallpaper to the room?
Answer:
The total cost of adding wallpaper to the room is 487.20
Answer:
The total cost of adding wallpaper to the room is $487.20
Step-by-step explanation:
Basically, how I got the answer is:
1. The shorter sides of the rectangle are 12 and the longer sides are 14.
2. The formula for a rectangle is A = l x w. The "l" means length and the "w" means width. 14 is the length and 12 is the width. So you should now have A = 14 x 12. If you multiply 14 by 12, you will get 168.
3. Since 1 square foot of carpet costs $2.90, then you should multiply by 168, which will give you $487.20 and that's pretty much it.
Hope this helps! :)
On a unit circle, the terminal point of theta is (sqrt 3/2, 1/2). What is theta if 0° <_theta< 360°?
A. 30°
B. 15°
C. 60°
D. 45°
I’LL MARK YOU BRAINLIEST IF YOU’RE CORRECT!!!!!!!
Answer:
30degrees
Step-by-step explanation:
On a unit circle, the terminal point of theta is (sqrt 3/2, 1/2). What is theta if 0° <_theta< 360°?
From the coordinate given;
x = √3/2
y = 1/2
theta = arctan(y/x)
theta = arctan(1/2÷√3/2)
theta = arctan(1/2 * 2/√3)
theta = arctan(1/√3)
theta = 30degrees
Hence the value of theta is 30degrees
On a unit circle, the terminal point of θ is (√3/2, 1/2). What is θ if 0° ≤ θ < 360°?
θ = 30°

On his math test, Balavan wrote that a four-sided polygon that has at least two right angles must be a rectangle or a square. Denna wrote that a four-sided polygon needs at least three right angles to be a rectangle or a square. Who is right? Explain your answer.
Answer:
a quadrilateral with 2 right angles could be a trapezoid so balavan is wrong. because if 3 angles are right angles the the fourth angle might also be a right angle and has to be a square or rectangle so denna is right
Step-by-step explanation:
Answer:
The sum of the angles in a quadrilateral is 360°, and a rectangle or square has four 90° angles.
A quadrilateral can be formed with two right angles and two angles that are other measures.
If three angles are 90°, the total is 270°, so the fourth angle is 90°.
Step-by-step explanation:
those are the 3 things you need
1 Serek is showing how to model the area
formula of a triangle
1) Original triangle
2) Create a congruent triangle.
Rotate it then join it to the original
triangle, forming a parallelogram.
3) Decompose the parallelogram
into a right triangle and a trapezoid.
4) Rearrange the triangle and
trapezoid to form a rectangle.
Which of these steps will identify the area
of the original triangle?
A Find the total area of the trapezoid
B Find half the area of the rectangle
C Find half the area of the trapezoid
D Find the area of the shaded triangle
5.80
Answer:
Find half the area of the rectangle
Step-by-step explanation:
Given
See attachment for the Serek's steps
Required
Which can be used to determine the area of the original triangle
To do this, we simply analyze each step.
At step 2, where he joined two congruent triangles to form a parallelogram.
Half the area of the parallelogram will give the area of the original triangle (since both triangles are equal)
At step 3, where he decomposed the parallelogram to a trapezoid and a right triangle.
Half the sum of the areas of the resulting shapes (trapezoid and right triangle) will equal to the area of the original triangle but half the area of each shape will not amount to the area of the original triangle
At step 4, where the right triangle and the trapezoid are merged to form a rectangle.
The area of the rectangle will equal to the area of the parallelogram in step (2).
So, half the area of the rectangle will equal to the area of the triangle.
Hence, (b) is correct
