Answer:

Step-by-step explanation:

As we know that in an hour there are 3600 seconds so

1.8 x 3600 = 6480

 6480 / 1609 = 4.02 miles / hr

Algebraic of coefficient of 3
N76 [4]

<span>In an algebraic expression, terms are the elements separated by the plus or minus signs. This example has four terms, <span>3x2</span>, 2y, 7xy, and 5. Terms may consist of variables and coefficients, or constants.</span>

<span>Variables
In algebraic expressions, letters represent variables. These letters are actually numbers in disguise. In this expression, the variables are x and y. We call these letters "variables" because the numbers they represent can vary—that is, we can substitute one or more numbers for the letters in the expression.</span>

<span>Coefficients
Coefficients are the number part of the terms with variables. In <span>3x2 + 2y + 7xy + 5</span>, the coefficient of the first term is 3. The coefficient of the second term is 2, and the coefficient of the third term is 7.</span>

If a term consists of only variables, its coefficient is 1.

<span>Constants
Constants are the terms in the algebraic expression that contain only numbers. That is, they're the terms without variables. We call them constants because their value never changes, since there are no variables in the term that can change its value. In the expression <span>7x2 + 3xy</span> + 8 the constant term is "8."</span>

<span>Real Numbers
In algebra, we work with the set of real numbers, which we can model using a number line.</span>

A circle is centered at the point (-7, -1) and passes through the point (8, 7).
Nookie1986 [14]
Radius is the distance from the centre to any point in the circumference. i.e. radius = \sqrt{ (-7-8)^{2} + (-1-7)^{2} } = \sqrt{ (-15)^{2} + (-8)^{2} } \\ = \sqrt{225+64} = \sqrt{289} =17
radius = 17 units

The density of an object can be calculated by dividing the object's mass by its volume. A rectangular prism has a density of 15g
weeeeeb [17]
Well, first you would divide 5625 by 15 to get the volume of the rectangular prism. So 375. Next, you would divide 375 by 3 which is 125 then by 5 do you get___. That would be your answer. So divide 125 by 5 to get your answer.

There were 436 tickets purchased for a major league baseball game. The general admission tickets cost ​$6.50 and the upper reser
Nataly [62]

Answer:

How many general admission tickets were​ purchased? __<u>136</u>__

How many upper reserved tickets we purchased? _<u>300</u>_

Step-by-step explanation:

Let the number of general tickets = g.

Let the number of reserved tickets = r.

6.5g + 8r = 3284

g + r = 436

     6.5g + 8r = 3284

(+)   -8g + -8r = -3488

--------------------------------

     -1.5g         = -204

g = 136

g + r = 436

136 + r = 436

r = 300

Answer:

How many general admission tickets were​ purchased? __<u>136</u>__

How many upper reserved tickets we purchased? _<u>300</u>_
