Answer:

-34/5

Step-by-step explanation:

5/6=-4/(x+2)

5/6(x+2)=-4

5/6x+10/6=-4

5/6x=-4-10/6

5/6x=-4-5/3

5/6x=-12/3-5/3

5/6x=-17/3

x=(-17/3)/(5/6)

x=(-17/3)(6/5)

x=-34/5

I know this is super easy! My brain just cannot wrap my head around my maths today. Please help soon.

Hello there! the answers to your question are:

a. $15x + $20y = $100; x + y = 6.

b. Yes, he can, since the cost of 4 shirts is $60, and two pants is $40, which adds up to be how much he is spending, or $100.  

Let's start by working to solve part a. We need to set up a system of equations that models the situation given. To do this, let's set up an equation that models how many Sean will buy in total and how much he will spend.

The question says that he wants to spend $100 total, and shirts cost $15 and pants cost $20. We can model this as $15x + $20y = $100.

The question also says he wants to purchase a total of 6 items for his wardrobe, so the number of items he buys has to add up to 6. This can be modeled as x + y = 6.

This gives us our answer for part a. Now let's solve part b. We are being asked if Sean can buy 2 pants and 4 shirts. This fits one of our equations, x + y = 6, since 4 and 2 add up to be 6. We need to see if this fits our other equation, though $15x + $20y = $100. To do this, we can substitute the number of shirts (4) into the x value, and the number of pants (2) into the y value and solve. If the total is more than 100, he can't. If it is less, he can.

$15(4) + $20(2) = 100

60 + $20(2) = 100

60 + 40 = 100

Since our total adds up to $100, he can buy 2 pairs of pants and 4 shirts.

I hope this helps and have a great rest of your day!

A driveway has an area of 96 square feet. The width of the driveway is 8 feet.
Mrrafil [7]

Answer:

12 feet

Step-by-step explanation:

A driveway is rectangular in shape.

Therefore we can calculate the area using the formula;

A = L \times W

From the question;

The area,A=96 feet square

The width, W=8 feet

We substitute this values into the formula to find the length, L.

This implies that

96 =L \times 8

Dividing through by 8.

\implies \frac{96}{8}= \frac{L \times 8}{8}

\implies L = 12

Hence,the length of the driveway is 12 feet.
