Answer:
24
Step-by-step explanation:
To figure out what the value of y is, we must isolate the variable. To do this, we need to use the division property of equality which says that when you divide on one side of the equal sign, you must also divide on the other side.
8y/8 = y
12/8 = 1.5
This tells us the value of y, so next we have to apply this into the problem
8(1.5) = 12
12 + 12 = 24
24 is your answer
3.9 = 4
4.2 = 4
5.5 = 6
6.3 = 6
Hopefully this is what you mean :)
Answer:
Step-by-step explanation:
sin (2x+14)=cos(x-5)
or 2x+14+x-5=90
3x=90-9=81
x=81/3=27°
F =

c + 32 Subtract 32 from both sides
F - 32 =

c Mutliply both sides by <span>

to cancel out the fraction
</span>

F - 17

= c Switch the sides to make it easier to read
c =
F - 17 <span>

C and D
5·(2+4) is 30, because u need to add parenthesis first. 2+4 is 6
6·5 is 30.
C is 5·6 and that is 30
D is 5·2 which is 10, then 5·4 which is 20. 10+ 20 is 30.
