Sorry if it’s confusing i tried color coding it
the measure of angle 6 is 71.5 degrees
Remember
(a/b)/(c/d)=(a/b)(d/c)=(ad)/(bc)
convert to improper fractions
8 and 1/2=8+1/2=16/2+1/2=17/2
2 and 1/4=2+1/4=8/4+1/4=9/4
8 and 1/2 divided by 2 and 1/4=
(17/2)/(9/4)=
(17/2)(4/9)=
(17*4)/(2*9)=
68/18=
34/9=
27/9+7/9=
3+7/9=
3 and 7/9
I'm smart but you probably wont like me
Answer:
Let's solve by eliminating x. Since 18 is the lowest common multiple , let's multiply the first equation by 3 and the second by -2.
18x−21y=24
−18x+10y=−2
Add the two equations.
−11y=22
Divide by -11 to isolate y.
y=−2
Substitute y=−2 into either of the 2 equations, I'll just use the second one.
9x+10=1
9x=−9
x=−1
Step-by-step explanation: that is your anwser
Answer=4000ft
There are 3280.84 feet in 1 kilometer
1km=3280.84ft
4000ft >3280.84 ft
therefore, 4000ft is longer than 1 km
4000ft>1km
