-3x -8y = -23
4(7x + 2y = -13)
-3x -8y = -23
28x + 8y = -52
25x = -75
x = -3
-3(-3) - 8y = -23
9 - 8y =-23
32 = 8y
y=4
Answer:
9.42 cubic inches
Step-by-step explanation:
In order to find the volume for a sphere, we use the formula V = πr. For the sake of simplicity, we will be using 3.14 for π. Before we plug anything in, let's get our radius. Remember, the radius is half of the diameter.
Equation: d = 2r
Replace: 6 = 2r
Divide: 3 = r
Now that we have our radius, let's plug in what we have and solve.
Equation: V = 3.14r
Replace: V = 3.14(3)
Multiply: V = 9.42
Remember, volume is measured in cubic units, so use cubic inches for the unit here.
Answer:
4y+3x+17
Step-by-step explanation:
take the similar numbers and add them together.
1. -2y+6y = 4y
2. 5x-2x = 3x
3. 8+9 = 17
Put the numbers back together into the new and simplified equation: 4y + 3x + 17
Answer:
0 and 0.695
Step-by-step explanation:
0=(0.695)- 14= 0.95
