-x=5, |-x|=5.............................
Answer:
x=
15
7
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
8x−
6
2
=x+12
8x+−3=x+12
8x−3=x+12
Step 2: Subtract x from both sides.
8x−3−x=x+12−x
7x−3=12
Step 3: Add 3 to both sides.
7x−3+3=12+3
7x=15
Step 4: Divide both sides by 7.
7x

Recall that the equation to solve for the volume of a cone is 1/3 * area of base * h
Since we have the radius and the height of the cone, we can put these into an equation:
1/3 * π(1.5)^2 * 4.5
(π(1.5)^2 is because we need to use the equation of the area of a circle in order to find the area of the base)
Square the 1.5:
1/3 * 2.25π * 4.5
The value of π is 3.14, so input that value:
1/3 * 2.25(3.14) * 4.5
Multiply 2.25 and 3.14:
1/3 * 7.065 * 4.5
Multiply all the values (You should use a calculator for this last part, since doing this by hand is a bit impractical):
1/3 * 7.065 * 4.5 = 10.5975
The sugar cone must be filled with 10.5975 cubic inches of ice cream.
-T.B.
My vote would be b. because generally when we are figuring area of a room, we are working with materials that are not exact and we usually round off .75 to the next foot. (I have experience in flooring!)
I am sure there are situations where you would want it to be exact however, such as using VERY expensive materials to cover.
Answer:
4f
Step-by-step explanation: multiply the outside number (1) by the number inside the parenthesis (4) and then add the letter.
