Answer:
X = 10/3
Step-by-step explanation:
8x - 4y = -40
y - 4x
10+2x - 4x = 10 - 2x
8(10 - 2x) -4(10 + 2x) = -40
x = 10/3

What are the steps to finding areas?
Trapezoid:
Rectangle:
Circle:
Triangle:
Answer:
Trapezoid: So basically to find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2.
Rectangle: To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.
Circle: The area of a circle is pi times the radius squared (A = π r²).
Triangle: To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles.

Please, help!!!! A fully loaded and fueled spacecraft can weigh close to million pounds. What is this weight converted to tons?
A fully loaded and fueled spacecraft weighing 4.6 million pounds is equivalent to 2,300 tons.
What is Unit of Measurement?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.
Given that a fully loaded and fueled spacecraft can weigh close to million pounds.
We need to find the find the weight converted to tons.
To convert pounds to tons, we divide the weight in pounds by 2,000
since there are 2,000 pounds in a ton.
4,600,000/2,000
= 2,300 tons
Therefore, a fully loaded and fueled spacecraft weighing 4.6 million pounds is equivalent to 2,300 tons.

A rectangular parking lot has a length of 84 feet and a width of 56 feet. Which of the following could be used to find the diagonal distance across the parking lot?
A. 84² – 56² = c²
B. (84 + 56)² = c²
C. 84² + b² = 56²
D. 84² + 56² = c²
Answer:
The diagonal is approximate is 101 feet
Step-by-step explanation:
Since the parking lot is rectangular, dividing it diagonally makes it two right angle triangles.
l = 84 ft and w = 56 ft
the diagonal becomes the hypothenus of the right angle triangle
so length and width are opposite and adjacent
Then we can now use pythagoras theorem, we will have
l² + w² = d²
84² + 56² = d²
7056 + 3136 = d²
10192 = d²
d² = 10192
d = √10192
d = 100.955
d ≈ 101 ft

Can you please check over my answer for volume and help me with the surface area?
Answer:
the surface area of the figure is 622 m ^2
the volume of the figure is 494 m ^3
Step-by-step explanation:
-you find the surface area for the rectangular prism and the triangular prism and add both answers.
- Rectangular prism S.A : 382 ^ 2 382m ^2 + 240m ^2 = 622 m ^2
- triangular Prism S.A : 240 ^ 2
-same thing with the volume,find the volume of the rectangular prism and the triangular prism and add those answers to find the total volume of your figure.
- Rectangular Prism Volume : 380 m^3 380 m ^3 + 114 m ^3 = 494 m ^3
- Triangular Prism Volume : 114 m ^3
formula for volume of a rectangular prism : V = w * l * h
formula for volume of a triangular prism : V = A * h
formula for surface area of a triangular prism simplified :
find the area of your base [area of the triangle on your triangular prism and since you have 2 multiply by 2,formula for area of 2 bases: A= 2 (1/2 * b*h) ) ]
next step-
formula for a surface area of a rectangular prism : 2 (w*l + l*h + h*w )
a-area w- width l-length
h-height s.a -surface area

Explanation:
Extend the side that's 9.5 meters long out to the left so that you form a trapezoid on top and a rectangle underneath. The side we extended is now 5+9.5 = 14.5 meters long.
Let
A = area of the trapezoid up topB = area of the rectangle underneathThe goal is to find A+B
The trapezoid has the parallel sides of 14.5 and 10 meters. The height of the trapezoid is 28-20 = 8 meters. So we can say
Area of trapezoid = height*(base1+base2)/2
A = h*(b1+b2)/2
A = 8*(14.5+10)/2
A = 98
The rectangle has area of B = length*width = 5*20 = 100 square meters
Therefore,
total area = A+B = 98+100 = 198 square meters.

Answer:
14.5 degrees
Step-by-step explanation:
The total amount of degrees in a triangle is 180
67.5+55=122.5 degrees
That means that there would be 57.5 (180-122.5) degrees left for the measure of angle 3x+14.
3x+14=57.5
-14 -14
3x=43.5
x=14.5
Answer:
Since this is an equilateral triangle, the two angles at he bottom are equal. 55-14= 41, and 41/3= 13 2/3, so x=13.6 repeating.
