Sorry i cant explain just know its extremly hard and i recomend the app photo math its the best!
I think this is the answer
=(3h+61)
Answer:
the equation
45 + 1.50d = 81
the answer
d = 24
step-by-step explanation:
45 per month is the set bill
1.50 changes per gigabyte
81 is the maximum
45 + 1.50x = 81
-45 -45
1.50x = 36
/1.50 /1.50
x = 24
1/5( 5/2 x 4/7 -11/7) + 3/28
Multiply the terms (5/2 x 4/7) in bracket then subtract it from 11/14. Result will be 10/7.
Then multiply 1/5 with 10/7. The result will be 2/7.
2/7 + 3/28 = 11/28

Answer:
I'm going to also give you how to get the answer... not just the answer.. you will need to know this for a test :/ so learn it :P
Step-by-step explanation:
Sin(30)=12
to remember what Sin and Cos at those speacial angles in degrees are.. just use this Sin(degrees)
Sin(0) = 0/2 =0
Sin(30)= /2 = 1/2
Sing(45) = /2 = /2
Sin(60)=/2 = /2
Sin(90)=/2 = 1
Cos is exactly the same but counts backwards from 90°
Cos(90) = 0/2 =0
Cos(60) = /2 = 1/2
Cos(45) = /2 = /2
Cos(30) = /2 = /2
Cos(0) =/2 = 1
note that the numerators just count from 0,1,2,3,4 , see? you can remember sin and cos now :) since you can count to 4 :P
Sin(30) =12
1/2 =12 while that statement makes no sense.... obviously 1/2 isn't equal to 12 but.. what's being said is that the angle of 30° gives you a side that is 12 units long.
so looking at what I wrote above.. which angle in degrees matches Sin when you look at Cos?
Sin(30)= 1/2 and Cos(60) also = 1/2 huh
sooo β = 60 °
got it? :/
