F = 1.8C + 32 *Replace C with 20
F = 1.8(20) + 32
F = 36 + 32
F = 68
F = 1.8C + 32 *Replace C with 25
F = 1.8(25) + 32
F = 45 + 32
F = 77
Room Temp. in Farenheit ranges from 68 to 77
<span>Call the first odd number x.
That means the next odd number would be x+2.
For example, if the first odd number is 9 then the next one would be 11, which is why it is plus 2. Okay?
So then, x+x+2=128
2x+2=128
2x=126
x=63
x+2=65
Thus, the two consecutive odd numbers are 63 and 65.
Hope I helped :)</span>
Answer:
42.3°
Step-by-step explanation:
Use SOH-CAH-TOA (O=opposite, A=adjacent, H=hypotenuse) we see that they give us the angle missing, x, but we first need to identify what method to use. They give us the opposite side from the angle, and they also give us the adjacent side from the angle, so TOA=tan.
now plug it in, since there is no angle then we plug it in as 
in the calculator, (be sure to be in degree mode)
x= 42.3°
(does that make sense)
Answer:
C. 7x+10
Step-by-step explanation:
First, distribute the 2
2(x+5) +5x
2*x+2*5 +5x
2x+10+5x
Combine like terms
2x+5x+10
7x+10
So, C is the correct answer
