Answer:
The system of equations are;
3x + 2y = 170
4x +6y = 360
Step-by-step explanation:
Form simultaneous equations and solve
Let x=price of children tickets
Let y=price of adult tickets
The Brown Family paid $170 for 3 children and 2 adults , this forms the equation as:
3x + 2y =$ 170
3x + 2y = 170 --------------------------equation (i)
The Peckham Family paid $360 for 4 children and 6 adults.
4x + 6y = $360
4x +6y = 360 ---------------------------equation (ii)
Solving the equations by graph will give value of x=30 and y=40
The price of children tickets was $30 and that of adults was $40
Scientific Notation is the way of <u>writing a number or expressing them</u> in a <u>shorter or more compact way.</u>
No, <u>Taylor's resoning is incorrect</u> because 2,800,000 =
From the question, we are given:
2,800,000 .
2,800,000 in scientific notation is .
The reason the power is not to the negative 6 is that we are moving from the right-hand side to the left-hand side 6 times.
Therefore, <u>Taylor's reasoning is incorrect. </u>
