<h3>
Step-by-step explanation:</h3><h3>(2/3)x - 2 = 7</h3>
(2/3)x = 7 + 2
(2/3)x = 9
2x = 9 × 3
x = 27/2
:. x = 13 1/2
#2 10:20 of that helps can u help me on my question
The answer i got was x=2 :)
Step 1: Simplify both sides of the equation.
x−2 over 3−(x+3 over 5)=−1
Simplify: (Show steps)
2 over 15x+−19 over 15=−1
Step 2: Add 19/15 to both sides.
2 over 15x+−19 over 15+19 over 15=−1+19 over 15
2 over 15x=4 over 15
Step 3: Multiply both sides by 15/2.
(15 over 2)*(2 over 15x)=(15 over 2)*(4 over 15)
Answer:
4 inches
Step-by-step explanation:
The surface area, A of a right square pyramid is given by :
A = a² + 2as
Where, s = height of each triangular surface = x
a = base edge of pyramid
Substituting values into the equation :
A = 84 in² ; a = 6 in ; Slant height, s = x
84 = 6² + 2(6 * x)
84 = 36 + 2(6x)
84 = 36 + 12x
84 - 36 = 12x
48 = 12x
48/12 = 12x / 12
4 = x
Hence, Slant height, x = 4 inches
