Answer:
x = -4
Step-by-step explanation:
Write and solve an equation in which the slope from the definition of slope is on the left side and the given slope, 4/7, is on the right side:
7 - 5 4
m = ---------- = --------
3 - x 7
Simplifying with the aim to find the value of x:
2(7) = 4(3 - x), or 7 = 3 - x. Then x = -4.
Answer:
170 tickets.
Step-by-step explanation:
Write formulas for the question.


Then use substitution.




So number of $3 tickets sold is 230. But they ask for the tickets bought in advance (i.e. the tickets sold for $2). Use substitution again.

19.625cm squared because you have to divide the diameter by 2 to get the radius.
Area of circle = pi times radius times radius
= 3.14 times 2.5 times 2.5
= 19.625cm squared
The best choice is 'C'. If it's 1, 5, and 4, then ideally, in 100 draws, you would expect 10, 50, and 40 ... pretty close to Tyrell's actual experimental results.
