Answer:
15/2
Step-by-step explanation:
2/3x-1=4
2/3x=4+1
2/3x=5
x=5/(2/3)
x=(5/1)(3/2)
x=15/2
Answer:
10.5 is the answer
Step-by-step explanation:
4(5y−8−2)=185−15
(4)(5y)+(4)(−8)+(4)(−2)=185+−15(Distribute)
20y+−32+−8=185+−15
(20y)+(−32+−8)=(185+−15)(Combine Like Terms)
20y+−40=170
20y−40=170
20y−40+40=170+40
20y=210
20y/20=210/20
y=21/2
y=10.5
Answer: 28 gallons of paint needed to paint 16 classrooms.

Answer:
93 degrees
Step-by-step explanation:
first, lets add 38+49 to see the sum
38+49=87
since the sum of all three angles in every triangle equals 180, we can subtract this sum from 180 to get the answer
180-87=93
so the missing angle would be 93
