Answer:
x= 20
Step-by-step explanation:
Step 1- Distribute into the parenthesis.
3x-1(3)-8= 1(4)+4x+5
Step 2- Multiply
3x-3-8= 4+4x+5
Step 3- Add.
3x-3-8= 4x+9
Step 4- Subtract 3x to both sides to move the variable to one side.
3x-11= 4x+9
-3x -3x
Step 5- Subtract 9 to both sides.
-11= 1x+9
-9 -9
-20= x
Exchange the signs.
20= x
Find the amount of the increase:
8.13 - 6.19 = 1.94
Divide the amount of the increase by the original price:
1.94 / 6.19 = 0.3134
Multiply by 100:
0.3134 x 100 = 31.34%
Round to the nearest tenth = 31.3%
Answer:
It is not equivalent because if you distributed (9w x 0)-12 = -108w.
Answer:
339.3 mi^2
Step-by-step explanation:
The formula for the surface area of a cylinder: 2pi*rh + 2pi*r^2
substitute the radius and height into this formula, and remember that radius is half of the diameter.
