Answer:
y = 4
Step-by-step explanation:
x1 y1 x2 y2
6 4 -6 4
(Y2-Y1) (4)-(4)= 0 ΔY 0
(X2-X1) (-6)-(6)= -12 ΔX -12
slope= 0
B= 4
Y =0X +4
Hi there!
Craig's reason is not reasonable because when you add fractions you have to find equivalent fractions.
The total distance in miles would be 1 1/8 miles.
By using a number line, line up the fractions, so then you could add them both.
Hope this helps :)
Answer:
what are the available options then I can answer
The answer is C. 5.000039x10^6.
In order to change something into scientific notation you have to move the decimal place enough times to get the first number to be between 1 and 9. After that, you must count how many space you moved it and that is your exponent. Moving the decimal space to the left gives you a positive exponent. Moving it to the right gives you a negative exponent.
Answer:
The easiest approach is to realise that one hour is 3 times longer than 20 minutes. The longer the time, the more they will pave.
215 of a mile, in 20 minutes, how much in 60 minutes?#
They will pave 3 times more.
215×31=615 of a mile
615=25 of a mile
You could also use the 'unitary method' where you find out how much they pave in ONE minute (divide by 20) and them multiply by 60 to find how much in one hour.
Look at what happens:
215÷20×60
=215×120×603
=215×3 ← exactly the same maths.
=25
