100,000 30,000 7,000
the first one i believe
A)
145 - 5d
5d = 145, set equal
29 days to lay all the track
b)
5*19 = 95
145-95 = 50
After 19 days, they have 50 miles to go.
What is the question? i could help you if i knew the question
Hey there!!
Let us take the first number as ' x '
According to the question
The second number exceeds the first number by 15
hence, the second number = x+15
The sum of both the numbers = 69
which means
x + x + 15 = 69
2x+15 = 69
Subtracting by 15 on both sides
2x + 15 - 15 = 69 - 15
2x = 54
dividing by 2 on both sides
x = 27
first number = 27
second number = 27 + 15
= 42
Hope my answer helps!
Answer: A
The y-intercept is 43, which means that at 0 hours it was 43 degrees. The slope is -2 so it means that the temperature is decreasing at a rate of 2 degrees per hour.
