Answer:
B. Subtraction property of equality
Step-by-step explanation:
If you subtract angle 3 from both sides, then angle two and angle four must be equal. The property you would be using is the subtraction property of equality.
Answer:
7.75-10°

Answer:
Step-by-step explanation:
1. We aren't worried about the area of the base, so the area is the area of the 4 triangles. Each triangle has an area of half the base times the height.
A = 4 (½ bh)
A = 2 bh
Given b = 6 and h (the height of the triangle, not the pyramid) = 5:
A = 2 (6) (5)
A = 60 ft²
2. This time, we want to include the area of the rectangular base, so:
A = b₁b₂ + 2 (½ b₁h₁) + 2 (½ b₂h₂)
A = b₁b₂ + b₁h₁ + b₂h₂
Given b₁ = 78 m, b₂ = 50 m, h₁ = 52 m, and h₂ = 60 m:
A = (78) (50) + (78) (52) + (50) (60)
A = 10,956 m²
Answer:
The answer would be (2,-1) or x = 2 and y = -1
Step-by-step explanation:
Building an expression, it is found that the value of the number is given by:
x = 3/50.
<h3>What is the value of the number?</h3>
We have to look at the text step by step, to build an expression involving an equality, and then solve it to find the value of the number.
We have that <u>negative one times the sum of twice of a number x and 3</u> is given by:
-1(2x + 3) = -2x - 3.
This is equals to two times the difference of 24 times the number and 3, hence:
-2x - 3 = 2(24x - 3)
48x - 6 = -2x - 3
50x = 3.
x = 3/50.
