(50-(x*50))+(40-(y*40))+20= discounted with 2 coupons
110-(z*110)= the price with the total coupon.
I believe these are the correct answers
Answer:
<h2>The answer is 19.36 miles per hours</h2>
Step-by-step explanation:
this problem is a unit conversion problem
In this problem, we are expected to convert from feet/min to miles per hour
given that the rate is 1760 feet per minute
from tables, we are given that
1 foot per minute is 0.011 miles per hour hence
1760 feet per minutes will give x miles per hour
cross multiplying we have
x= 1760*0.011
x= 19.36 miles per hours
Answer:
Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to
where
m is the slope
b is the y-intercept
<em>Find the slope</em>
The formula to calculate the slope between two points is equal to
take the points
(0,2.5) and (100,97.5)
substitute in the formula
Find the y-intercept b
we have
substitute i the linear equation
solve for b
Note It was not necessary to calculate the value of b because the value is given in the table
Remember that the y-intercept is the value of y when the value of x is equal to zero (the y-intercept is the point (0,2.5))
The linear equation is
