Answer:
5/12
Step-by-step explanation:
The whole book can be represented as 12/12 because 12 divided by 12 equals one whole ( or one). 1/3 * 4/4(one rewritten) = 4/12 We then need to add this to 1/4 * 3/3 (one rewritten again) = 3/12
4/12 + 3/12 == 7/12
7/12 is the amount Julie did read so we subtract this from 12/12 to get the answer:
5/12
A=100°
as 180-140= 40 , 40 x 2 = 80 & 180-80 = 100° = a

i’m not too sure sorry boo xxo
6n−20=−2n+4(1−3n)
Simplify both sides of the equation.
−6n−20=−2n+4(1−3n)
−6n+−20=−2n+(4)(1)+(4)(−3n)(Distribute)
−6n+−20=−2n+4+−12n
−6n−20=(−2n+−12n)+(4)(Combine Like Terms)
−6n−20=−14n+4
−6n−20=−14n+4
Add 14n to both sides.
−6n−20+14n=−14n+4+14n
8n−20=4
Add 20 to both sides.
8n−20+20=4+20
8n=24
Divide both sides by 8.
8n/8 = 24/8
