<u>Answer:</u>

4x.

<u>Step-by-step explanation:</u>

we will <em>begin</em> by solving the problems.

  • 2x - 3 = 1x
  • x + 1 = 1x

<em>after</em> we have done that we will find the <em>perimeter</em>.

remember: The perimeter of a rectangle is the total length of all the sides of the rectangle. Hence, we can find the perimeter by adding all four sides of a rectangle. Perimeter of the given rectangle is a + b + a + b.

  • we know all side are 1x.

<u>so the equation is 1x + 1x + 1x + 1x</u>

  • which would equal to <em><u>4x.</u></em>

Seven times the first (smaller) of two consecutive odd integers is equal to five times the second (larger) integer. Find each in
lbvjy [14]
<h2>Answer:</h2>
  • The smaller consecutive odd integer is: 5
  • and the larger consecutive odd integer is: 7
<h2>Step-by-step explanation:</h2>

Let the smaller odd integer be: a

then the larger odd integer which is consecutive to a will be: a+2

It is given that:

Seven times the first (smaller) of two consecutive odd integers is equal to five times the second (larger) integer.

This means that:

7 times of a is equal to 5 times of (a+2)

i.e.

7a=5(a+2)\\\\i.e.\\\\7a=5\times a+5\times 2

( Since, by using the distributive property of multiplication)

i.e.

7a=5a+10\\\\i.e.\\\\7a-5a=10\\\\i.e.\\\\2a=10\\\\i.e.\\\\a=5

Hence, the smaller number is:  5

and the larger number is: 7

( Since a+2=5+2=7 )

what is the total utility at 4 units and the marginal utility when jack goes from consuming three pop tarts to four pop tarts?
Verizon [17]

The total utility of 4 units is 50 and the marginal utility is 5

Total utility is the sum of satisfaction that is derived from the consumption of units of a good or service.

Total utility can be determined by adding the marginal utility of each unit that is consumed.

Total utility of consuming 4 units =<em> marginal utility</em> of the first unit + <em>marginal utility</em> of the second unit + <em>marginal utility</em> of the third unit + <em>marginal </em>utility of the fourth unit  

20 + 15 + 10 + 5 = 50

Marginal utility is the change in total utility when consumption increases by unit. Marginal utility is 5

Please find attached the table used in answering this question. To learn more about marginal utility, please check: brainly.com/question/14149928?referrer=searchResults

Plz answer if you know it....

Sales tax is charged on the subtotal (amount before tax).

First, find the subtotal by adding up all of the amounts.

4(675) + 2(110) + 5(41) + 6(135) + 230(2.50)

2700 + 220 + 205 + 810 + 575

Total = 4510

Next, we need to find 7% of 4510. That number is the sales tax.

0.07 x 4510 = 315.70

Sales Tax = $315.70

Total Amount (with tax) = $4825.70

Hope this helps!! :)
