Answer:
30x - 18
Step-by-step explanation:
First, you would use the distributive property to get rid of the parenthesis and to simplify your equation.
6 * 5x gives you 30x and 6 * -3 is equal to -18
This gives you 30x - 18

Explanation:
50/2.5=20
50/5=10
20-10=10
2. m=-1.5
Explanation
5+7=12
-5-3=-8
12/-8=-1.5

74=2x
x=37
Answer:
Step-by-step explanation:
The volume of a cylinder is expressed as
V = πr^2h
Where
π is a constant
h is the height of the cylinder
The volume of a cone is expressed as
V = 1/3πr^2h
Where
π is a constant
h is the height of the cone
If the cylinder and a cone have congruent bases and the same volume, it means that
πr^2h = 1/3πr^2h
πr^2 cancels out on both the left hand side and right hand side of the equation. It becomes
h = h/3
It means that the height of the cone is 3 times the height of the cylinder. Therefore,
If height of cylinder = 4 cm, height of cone = 12 cm
Answer:
Step-by-step explanation:
Remark
They are asking you to combine like terms. The total should be 180.
Givens
2 angles
Total 180
Solution
8x - 3 + 4x + 3 = 180 The threes cancel. So add what's left. They are of opposite signs, so they cancel.
12x = 180 Divide both sides by 12
12x/12 = 180 /12
x = 15
