Answer:
10
Step by step explanation:
In general, if we have an equation that has just one variable, such as x, then "solving the equation" means finding the set of all values that can be substituted for the one variable to produce a valid equation.
Isolate "x" on one side of the algebraic equation by adding the negative number that appears on the same side of the equation as the "x." For example, in the equation "x - 5 = 12", rewrite the equation as "x = 12 + 5" and solve for "x."
x + (-6) + (-8) = -4
x + (-6 + -8) = -4
x + (-14) = -4
x + (-14 + 14) = -4 + 14
x = 10
Step-by-step explanation:
we know,
volume of pyramid = 1/3 × base area × height
so,
→ 1/3 × 120 × 9
→ 40 × 9 = 360 ft
so the volume of the pyramid is 360 ft².
base area = length × slant height
so, 12 × 10 = 120

Answer:
696.9 cm^3 to the nearest tenth.
Step-by-step explanation:
Radius of the egg = 1/2 * 11 = 5.5 cm.
Volume = 4/3 * pi * 5.5^3
= 696.9099703
