<h3>
Answer:</h3>
270 minutes
<h3>
Step-by-step explanation:</h3>
(60 minutes/hour) × (4.5 hours) = 270 minutes
The answer will be: Y = -2/5x - 4
Slope intercept form: y= Mx+b
You find the slope (M) using: rise/run formula
You find (b) by looking at the y-intercept
Answer:
The answer is 
Step-by-step explanation:
when writing scientific notation, there must be one number to the left of the decimal point.
To achieve this in this problem, you need to move the decimal point 3 times to the right.
because you are moving the point to the right, the exponent will be negative.
*rule of thumb: moving the decimal to the left will give you a positive exponent, moving to the right will give you a negative exponent*
therefore you answer should be written as:

150mm is the same as 15cm
15cm:60cm
both divisible by 15
1cm:4cm

Answer:
slope is 9
Step-by-step explanation:
use the formula y=mx+b wherein m is the slope and b is the y-intercept
to solve for m, use formula (y2-y1)/(x2-x1):
=
(you add 5 and 9 together because negative + negative is positive)
126/14 = 9
