Answer:
5
Step-by-step explanation:
Step 1:
x - 2 = 3x - 12
Step 2:
- 2 = 2x - 12
Step 3:
10 = 2x
Step 4:
5 = x
Hope This Helps :)
Substitute x=0 in the equation and find the value for y that makes the resulting equation true. For example, in the equation x-2y=2, when x=0, the equation becomes -2y=2. Since y=-1 makes this equation true, one point on the line is (0,-1)
The answer is-6 because if you use a calculator it’s -6
Answer:
369.5 ft²
Step-by-step explanation:
Separate the figure into 2 rectangles and 2 triangles.
(see attached image)
<u>Area 1</u>
Area of a rectangle = width × length
= 4 × 5
= 20 ft²
<u>Area 2</u>
Area of a rectangle = width × length
= 8 × (4 + 4 + 5)
= 8 × 13
= 104 ft²
<u>Area 3</u>
Area of a triangle = 1/2 × base × height
= 1/2 × (6 + 4 + 5 + 4 - 6) × 23
= 1/2 × 13 × 23
= 149.5 ft²
<u>Area 4</u>
Area of a triangle = 1/2 × base × height
= 1/2 × 8 × (21 + 8 - 5)
= 1/2 × 8 × 24
= 96 ft²
<u>Total Area</u>
Area 1 + Area 2 + Area 3 + Area 2 = 20 + 104 + 149.5 + 96
= 369.5 ft²
<u>Answer</u>
6
<u>Explanation</u>
let n be the first even number in the sequence.
The 2nd term = n + 2
3rd term = n + 2 + 2
= n + 4
4th term = n + 4 + 2
= n + 6
The sum of these number = 36.
∴ n + (n +2) + (n + 4) + (n + 6) = 36
4n + 12 = 36
4n = 36 - 12
4n = 24
n = 24/4
= 6
The first term is 6.
