In this item, we are given that the number of miles that John runs every day vary. Therefore, it is just rightful that we use three different variables for the number of miles he ran for three days. For the purpose of representation in this item, we let the variables be x, y, and z. The total miles he ran is equal to the sum of the three variables. Let T be the total and that would be equal to,
<em> T = x + y + z</em>
Answer:
v = 4
Step-by-step explanation:
<em>u + at = v</em>
a (-2) multiplied by t (3) = -6
-6 + u (10) = 4
Answer:
y=20x+14, where:
y is the total amount you would pay for using the sailboat
x is the number of hours the sailboat is used
Step-by-step explanation:
An equation in slope-intercept form is set up as y=mx+b. From the information provided, the equation would indicate that the cost of renting the boat would be equal to the price per hour for the number of hours plus the cost of lifejackets and the equation in slope-intercept form that can be used is:
y=20x+14, where:
y is the total amount you would pay for using the sailboat
x is the number of hours the sailboat is used
Answer:
396
Step-by-step explanation:
Difference of two squares is breaking down numbers into pieces and using the distributive property to solve. The pieces should be in the form (a-b)(c+d).
Write 22 as (20 + 2) and 18 as (20-2).
(20+2)(20-2) = 400 + 40 - 40 - 4 = 400 - 4 = 396
19-15 = C Number of students over the course of a year!
19-15 gives us a total of 4 students over the course of the year!
So the value of C is 4 students
