Answer:

I'll tell u later

Step-by-step explanation:

Small number =x

Large number =11 plus x

Now from the question,

x + 11 + x = 57

Therefore 2x plus 11= 57

2x= 57-11=46

X=46÷2=23

Help pleaseeeeeeeeeeee
ollegr [7]

Answer:

Step-by-step explanation:

The temperature at a given altitude is

y = 36 - 3x

The temperature on the surface of the planet is the point (0,t) where t is the temperature for the given height.

y = 36 - 3*0

y = 36

So at the surface of the planet is 36 degrees C.

======================

Effectively it is the slope of the equation which is - 3

So ever km going up will mean a loss of 3 degrees. I think they want you to write -3

A. 3.4
seropon [69]
A is your answer 3.4

Use Pythagorean Theroum

10.2 squared = 9.6 squared + x squared
104= 92.6+x squared
x squared = 11.4
x= 3.37
round x to 3.4

Hope that helps!
