Answer:
x=lindas age
3 times lindas age (3 time x or 3x) is decreased by 36 (-36), the result (=) is twice lindas age (2 times x or 2x)
now we have
3x-36=2x
subtract 2x
x-36=0
add 36
x=36
age=36

Answer:
(0, 3) lies on the line joining (2, -2) and (-4, 13).
Step-by-step explanation:
The equation of the line joining the points (2, -2) and (-4, 13) is:
-2(y + 2) = 5(x - 2)
-2y - 4 = 5x - 10
5x + 2y - 6 = 0
When we substitute x = 0 and y = 3,
5(0) + 2(3) = 0 + 6 = 6
So, (0, 3) lies on the line joining (2, -2) and (-4, 13).
Answer:
V = 3,367.6 cm³
Step-by-step explanation:
Diameter of sphere (D) = 18.6 cm
radius (r) = ½(18.6) = 9.3
π = 3.14
Formula for volume of a sphere = ⁴/3πr³
Plug in the values
V = ⁴/3 × 3.14 × 9.3³
V = ⁴/3 × 3.14 × 804.357
V = (4*3.14*804.357)/3
V = 3,367.57463
V = 3,367.6 cm³ (nearest tenth)
Answer: It will take approximately 21 years.
Step-by-step explanation:
6 percent of 5.25 is 0.315 (5.25 x 0.06 = 0.315)
Then you subtract 5.25 from 12 to calculate the number of years. (12 - 5.25 = 6.75)
Divide 0.315 from 6.75 (6.75 / 0.315 ≈ 21.4)
