Using a system of equations, it is found that he bought 18 twigs.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variable is the amount n.
Nine times the square of the twigs he bought there Is half of their cube, hence the equation is:
Then, applying cross multiplication:
He bought 18 twigs.

Answer:
The closest answer is 12.
Step-by-step explanation:
Since 12 multiplied by 35 is 420, it is the closest answer. 16.5 seconds is too much. 335 seconds is WAY too much to reach 407 meters. 8.15 seconds is too little. It is at least half of how much you want it to move.

Range means how different the highest and lowest numbers are. 50-220 is wayyy bigger than 30-150.
Median is the average earnings. On average, the older kids are earning more money than the younger ones.
Answer:
y = x + 3
Step-by-step explanation:
The equation of a line is y=mx + b, where m is the slope and b is the y-intercept.
In this case, the slope of the line is 1, and the y-intercept (the point where the line crosses the vertical axis) is 3. So you just need to plug in the 3 in place of b.
y = mx + b
m = 1
b = 3
y = x + 3
