Answer:
x=3
Step-by-step explanation:
We are taking 2 times the sum ( addition) of 18 and x
2 ( 18+x) = 42
Divide each side by 2
2 /2 ( 18+x) = 42/2
18+x = 21
Subtract 18 from each side
18+x-18 = 21-18
x = 3
Answer:
49
Step-by-step explanation:
x + 100 + 31 = 180
x + 100 + 31 - 100 - 31 = 180 -100 -31
x = 49
Since 35 and 48 have no common factor greater than ' 1 ',
there's no number by which the numerator and denominator
can both be divided. That means the fraction is already in
lowest terms (simplest form).
Answer:
14 1/3
Step-by-step explanation:
The y - intercept is where the line cuts the y- axis... or vertical axis. this is her height when the observer first sees her
pick 2 points on the line and find the slope
say (0, 4500) and (1, 3000)
slope = change in altitude/change in time
= (3000 - 45000)/(1 - 0)
the x intercept is where the line cuts the x-axis.. horizontal axis
it shows the time it took the skydiver to travel from 4500 feet to the ground.
Hope it helps
