Answer:
861 : 615
Step-by-step explanation:
7 + 5 = 12
246 ÷ 12 = 123
7 × 123 = 861
5 × 123 = 615
861 -65 = 246
<em>Absolute value represents distance from zero on a number line.</em>
<em>-7 and 7 are the same distance away from zero, 7 units.</em>
<em>To visualize this, take a look at the image I have made below.</em>

Complete Question :
The surface area of a given cone is 1,885.7143 square inches. What is the slant height?
Answer:
25 inches
Step-by-step explanation:
In the diagram, we are given the following information
Height of the cone = 20 inches
Radius of the cone = 15 inches.
The formula for the slant height of a cone represented by l =
l² = r² + h²
l = √(r² + h²)
l = √(15² + 20²)
l = √(225 + 400)
l = √625
l = 25 inches
Therefore, the slant height of this cone = 25 inches
Answer:
x=-1
Step-by-step explanation:
First distribute...
0.5x + 1.4 - x = 0.6 + 0.3
Then add your like terms...
-0.5x + 1.4 = 0.9
Solve like normal equation....
-0.5x = 0.5
x= -1
