Answer:
19.4 liters
Step-by-step explanation:
You get 19.4 by multiplying 9.7 by 2 which = 19.4
Write an equation system based on the problem
"Agatha is five times older than her son, Bob" could be written as:
a = 5b.......(first equation)
"Three years ago, she was nine times older" could be written as:
a - 3 = 9(b - 3)......(second equation)
Solve the equation system
To find the value of b, substitute 5b as a to the second equation
a - 3 = 9(b - 3)
5b - 3 = 9(b - 3)
5b - 3 = 9b - 27
5b - 9b = -27 + 3
-4b = -24
b = -24/-4
b = 6
Her son, Bob, is 6 years old
To find Agatha's age, substitute the value of b to the first equation
a = 5b
a = 5 × 6
a = 30
Agatha is 30 years old
Answer:
Notice on the graph y = sin x, the graph passes through the origin (0,0). Then the graph crosses the x-axis at (p,0). When we make c positive, we move the graph to the left c units
