Volume of triangular pyramid = 1/3 b²h
Use the formula to find your answer.
Answer:
x = 3
Step-by-step explanation:
Simplify the equation to -3x + 12 + x = 2x, and then to -2x + 12 = 2x. Now you have to make the x values on one side so now you are left with 12 = 4x, so you just simplify by dividing 12 by 4. The answer is 3 = x.
Answer:
Step-by-step explanation:
Tanisha, Elicia, and Ajua are cousins. Tanisha is twice as old as Ajua, and Elicia is two years older than Tanisha. The sum of all their ages is 37. Use variable expressions and calculate the age of each girl
Let us represent:
The age of :
Tanisha = a
Elicia = b
Ajua = c
Tanisha, Elicia, and Ajua are cousins. Tanisha is twice as old as Ajua
a = 2c
c = 2/a
Elicia is two years older than Tanisha.l
b = a + 2
The sum of all their ages is 37.
a + b + c = 37
We substitute
a + a + 2 + 2/a = 37
2a + 2 + 2/a = 37
Use variable expressions and calculate the age of each girl
It looks like 19 would be.
I don't know any slick way to find it, other than just slugging it out.
