Answer:
x equals 2
Step-by-step explanation:
.3-.2+.3 is .4
.4 divided by .2 is 2
then you are left with 2 = x
Step-by-step explanation:
x+13÷2×2=4×2
x+13=8
x+13-13=8-13
x=8-13
x=-5
Answer:
She had 22 friends at her graduation party.
Step-by-step explanation:
70 chocolates total minus 3 chocolates times the number of friends she had at the party = 4
70-3x=4
Subtract 70 from both sides of the equation
-3x=4-70
Simplify
-3x=-66
Divide both sides of the equation by -3
-3x/-3=-66/-3
Simplify
x=22
The estimate of the problem would be 1/4 because 6/8- 1/2 you would get 1/4.
~Good Luck!~
Answer:
34.54 
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Height (h) = 3.7 km
Base radius (r) = 3 km
We can calculate the volume of mountain by using following formula,
So, volume of cone = (1/3)π
h
By putting the value in the formula, we get
= (1/3) π × 
× 3.7
= 11.1π
= 34.54
Hence, the volume of the mountain is 34.54 .
