4x + 5 – x = 10 + 3x + 4 ***please include the work with it

Answers

Answer 1

Answer:

First, you’ll have to collect like terms

4x-x-3x=10+4+5

Next, step is to solve

3x-3x=14+5

0=19

Step-by-step explanation:

I hope the answer to your question is 19, please give me brainliest

Answer 2

Answer:

x =∅ (No solution)

Step-by-step explanation:

First, simplify each side by combining like terms:

3x + 5 = 14 + 3x

So you want to get x to one side and everything else to the other. Subtract (3x) and (5) from each side.

0 = 9

Because 0 does not equal 9, there are no solutions.

Answer:

Elena's running speed is 5 miles/hour

Explanation:

The speed is defined as the covered distance per unit time

In the problem, we have:

The distance covered is the length (circumference) of the circular track which is given as of a mile.

We are also given that she completes each lap (she completes of a mile) in of an hour

To get her speed, we will divide the distance covered by the time taken to cover this distance

This is done as follows:

speed = miles/hour

This means that:

Elena can run 5 miles each hour

There is only one variable in this situation which means you can rule out A and C, B is wrong because it said it wants Y, so D is your answer!

Answer:

The answer would be 'D': y=6.5x

Step-by-step explanation:

Since y would be the total amount, it'd be weird if it was x=6.5y since the part would be more than the total. Plus, for every roll, it sells for $6.50, and when it multiplies by x (the amount sold) you would get y (the total).

1. Using the following dilated coordinates of a triangle choose the appropriate scale factor.
J:(2.4)---J':(4,8)
K:(1,1)----K':(2,2)
L:(4.0)----L':(8,0)

A.5
B.4
C.3
D.2

Answers

Answer:

Step-by-step explanation:

The scale factor is 2. So, the correct option is D.

Important information:

[tex]J(2,4)\to J'(4,8)[/tex][tex]K(1,1)\to K'(2,2)[/tex][tex]L(4,0)\to J'(8,0)[/tex]

We need to find the scale factor.

Scale factor:

If a figure is dilated by factor [tex]k[/tex] with origin as the center of dilation, then

[tex]P(x,y)\to P'(kx,ky)[/tex]

Using this rule, we get

[tex]J(2,4)\to J'(2k,4k)[/tex]

We have [tex]J'(4,8)[/tex]. So,

[tex]J'(2k,4k)=J'(4,8)[/tex]

On comparing both sides, we get [tex]2k=4[/tex] or [tex]4k=8[/tex]. In both cases, the value of scale factor is [tex]k=2[/tex].

Thus, the correct option is D.

Using the information below, work out how much Lila paid for the chainsaw.

Hire Fees
Monday to Friday - $37 a day
Saturday and Sunday - $42 a day

Answers

Answer:

She payed $269 for the chainsaw :)

First, if she used it Monday to Friday, that’s 5 days. 5 x 37 = $185
Secondly, if she used the chainsaw on Saturday and Sunday too, and if 2 x $42 = $84, then she would have paid $84 for the Saturday and Sunday in which she used the chainsaw.

Add up both of cost of the days she used the chainsaw and you get a total of $269
