A truck rental company charges a $25 rental fee when someone rents.a

nirvana33 [79]

Answer:

25 +15x

Step-by-step explanation:

so the fee to rent a truck is 25 but for every hour that you have it, you have to pay $15, so x represents the number of hours you have the truck, so if you have the truck for 3 hours, you would say 25+15(3)= $70

Evaluate 4(2a – b) when a = –1 and b = 5.

grin007 [14]

Hey There!

<h2>Question:-</h2>

$\sf \longmapsto \: 4(2a - b)$

This is a algebraic expression. The values of a and b are given. The values are as follows :-

a = -1

And,

b = +5 .

<h2>Solution:-</h2>

$\sf \longmapsto4(2a - b)$

Note that a is multiplied with 2 that is :-

$\sf \longmapsto4(2 \times a \: - b)$

Now, Insert the values that is a = -1 and b = 5 :-

$\sf \longmapsto4(2 \times - 1 - 5)$

Here,we need to follow BODMAS Rule.

B = Brackets

O = Orders

D = Division

M = Multiplication

A = Addition

S = Subtraction

We need to solve the bracket's calculations first as it is the rule.

So, Firstly Multiply (2 × -1) :-

$\sf \longmapsto4( - 2 - 5)$

Note that, (-) × (-) equals to (+).

So, it will be 5+2,But as 5 is bigger number than 2, 5 contains a minus sign.So the result will be -7.

$\sf \longmapsto4( 5+ 2)$

On Simplification:-

$\sf \longmapsto4( - 7)$

$\sf \longmapsto4 \times (- 7)$

$\sf \longmapsto \: - 28$

______________________________________

Henceforth the solution of the algebraic expression is :-

$\bf \:- 28$

Option B is correct!

I hope this helps!

Answer with solution

adelina 88 [10]

In general, the scalar multiple of k times u, is this:

 $k\vec u = k(ux, uy)=(Kux,Kuy)$

So, here's how we find $3\vec v$

$3\vec v = 3 * (2,4) = (3*2,3*4) 

= (6,12)$

The answer is (6,12).
