In a triangle all the angles add up to 180 degrees.So we know that
(6x-1)+20+(x+14)= 180
6x+x+14-1+20=180
v v
7x + 13 + 20= 180
v
7x + 33=180
-33 -33
0 147
7x/7 = 147/7
x = 21
x=21
Then you substitute:
(6x-1) (x+14)
(6×21-1) (21+14)
v v
126-1 35
125 degrees / 35 degrees
125+35+20=180
13.41
1 - is the tens place
3 - is the ones place
4 - is the tenths place
0 - is the hundredths place
6 - the thousandths place
There for 6 is grater then 5 rounding up 0 to 1
if the 6 was a 5 it would STILL round up to 1
To change a/x=d/a to <span>a²=cd, you need to take the following steps:
1. Pass the "a" to the left side and the "c" to the right side:
(a)(a)/c=d
(a)(a)=cd
2. Finally, multiply "a" by "a":
a</span>²=cd (By definition, when you have to multiply exponents with the same base, you should add the exponents. As you can see, both bases "a" have exponents 1, so, when you multiply them, you have to rewrite the base and then add these exponents: a^1+1=a²).<span>

Answer:
30 mph
Step-by-step explanation:
train stopped after 520 miles
780 miles to go
stopped at 20 hours
stopped for 4 hours
34 hours used up...
26 hours left
780 miles to go
780 miles/26 hrs = 30 m/hr
Slope: (y2-y1)/(x2-x1) = m
Find the slope, m, then pick a point, plug in the x, y, and m, and solve for b in the equation:
y = mx + b
That is your y-intercept.
Take out your x and y, plug in m and b, and that is your generic form for your line, t.
