This shape can be broke down into 2 rectangles and 2 triangles.

Let’s first find the area of the bigger rectangle:

To find area you just multiply l•w, or length•width.

For the big rectangle, the length is 20, and the width is 5. When these are multiplied you get 100.

So, the area of that first shape is 100. Now we have to find the others, using the same process!

The small rectangle has a length width of 4, but the length is not there.

In order to find the length, you have to use the bigger rectangles length, but subtract the left and right sides (the 5’s).

So it looks like this;
20-5-5 = 10!

The length is 10 and the width is 4. Now just multiply!

10•4 = 40

Now for the last shapes. Typically with a triangle you would divide it by two, but since you already have to triangles, you can combine them to make like a square shape.

So, once again, you do l•w:
5•4=20
(no further steps since you have two triangles already)

Now that we have the area of every individual shape, you just add them all!

100+40+20= 160

Your answer is 160 (but make sure to add in your unit, and when finding area you have to add the little 2)

So it’s 160in.^2

Alex must read at least 500 pages of his book this month. He has already read 260 pages. If he reads 30 pages a day, what is the minimum number of days he needs to read to reach his goal?

So he has to read 500 and he already read 260 500 - 260 = 240. 240 divided by 30 equals 8. So the answer will be 8 days

what is x and y of 2x-4y=10&x+5y=40

Answers

Answer:

[tex]x = 15, y = 5[/tex]

Step-by-step explanation:

We are given that

[tex]2x - 4y = 10\\x + 5y = 40[/tex]

When given these types of equations, we can manipulate them in order to cancel out a variable. Cancelling either the x or y works, choose which one is easier.

In this case, we can multiply the second equation by -2 and easily cancel out the x's

[tex]2x - 4y = 10\\-2x - 10y = -80[/tex]

Now we can add the two equations

[tex]-4y + (-10y) = 10 + (-80)\\-4y - 10y = -70\\-14y = -70\\y = 5[/tex]

We can substitute y into the second equation and solve for x

[tex]x + 5(5) = 40\\x + 25 = 40\\ x = 15[/tex]

Check:

2(15) - 4(5)

30 - 20 = 10

it works

Marshall bought 32 ounces of mixed nuts, which are estimated to be 30% peanuts. Which expression can be used to find the percentage of peanut concentration of the final mix if he adds x ounces of peanuts?

Answers

Answer:

2nd choice

Step-by-step explanation:

to find the inital peanuts, we multiply 32 ounces by 3/10 or 0.3. then we add x which are peanuts as well. that makes 0.3 x 32 + x. this is our total peanuts. to find the percantage, we find the whole mixture which is now 32 + x, divide peanuts by the whole mixture and multiply by 100.

$300

Step-by-step explanation:

So the equation would look like this since you pay a one time fee on $60 that is the y-intercept, and since you pay $40 per month that is you m or slope constant rate of change etc.

The equation looks like this.

y = 40x + 60

Since it wants to know how much after 6 months plug in 6 where the x is.

y = 40(6) + 60

y = 240 + 60

y = 300

$300

Hope this helps!!

Answer:

$420.00

Step-by-step explanation:

Let x = cost after 9 months. Let y = cost of phone.

x = y + (r · t)

y = $60.00

r = monthly rate of $40.00

t = time period of 9 months

x = $60.00 + [($40.00/month)(9 months)]

The months cancel, leaving dollars.

x = $60.00 + [$360.00] = $420.00
