Answer:
43°
Step-by-step explanation:
(x + 53)° + (x + 74)° + 73° = 180°
(x + 53 + x + 74)° = 180° - 73°
(2x + 127)° = 107°
2x + 127 = 107
2x = 107 - 127
2x = - 20
x = - 20/2
x = - 10

5 + 5 + 5 = 15
15 + 2 = 17 trophies
(5 x 3) + 2 = x (This is a possible way of writing the expression.)
The answer is got is X=5 :)
Answer:
She rode 17.4 miles in 1 hour
Step-by-step explanation:
A cyclist rode for 3.5 hours and completed a distance of 60.9 miles. If she kept the same average speed for each hour, how far did she ride in 1 hour?
Part A Estimate the quotient. Include an equation to show your work. Explain your thinking.?
The quotient is the average speed and this is calculated as:
Speed = Distance(miles)/Time(hours)
Where speed = quotient
Distance = Dividend
Time = Divisor
Speed = 60.9 miles/3.5 hours
= 17.4 miles/hour
Part B Find the exact distance she rode in 1 hour by completing the division. PLEASE HELP!
If :
3.5 hours = 60.9 miles
1 hour = x miles
Cross Multiply =
3.5x = 60.9 miles
x = 60.9/3.5
x = 17.4 miles
Hence, she rode 17.4 miles in 1 hour

That Parabola's equation is 
Step-by-step explanation:
I can't really explain much, but the top equation is a formula for <em>all </em>equations for a parabola. h and k are the x and y-values of the vertex. a is, well, a.
How did I find the equation of the parabola? Simple. Since the vertex is on the origin, h and k are 0. Also, because it intercepts (2,4) and (1,1), a=1.
