Answer:
5x+6=3
Step-by-step explanation:
"A number" is a variable.
"Sum" is addition.
"Equals 3" is =3.
"and six" relates to "sum".
So when you put these together it would be 5x+6=3
1 km=0.621mi
xkm=106 mi
x=106/0.621=170.66
b is the answer
Answer: 7.012 x 10−8 ==> Option 3
Step-by-step explanation:
(3.012 x 10−8) + (4 x 10−8)=
(3.012+4) x 10−8=
(3.012+4.000) x 10−8=7.012 x 10−8 ==> Option 3
If we call y the height of the plane, we know when the time (x) is 0, the height is 30000. So let's write that in:
y = 30000 + (0)
Then, for every increase of a minute (x increases by 1), the height reduces by 2000. This can be written as:
y = 30000 - 2000x
Using what we know about y = mx+c equations, the slope of the line is -2000, and the y-intercept is (0, 30000).
