A perimeter increased by four is twenty eight.
(As an equation)

Answers

Answer 1

Answer:

P+4=28, meaning that the original perimeter was 24

Step-by-step explanation:

Let's call the perimeter P.

Converting the words into an equation, you get:

P+4=28

Now, you can subtract 4 from both sides:

P+4-4=28-4

P=24

Answer:

1.5 miles less

Step-by-step explanation:

Step 1:  Find equation for Alexanda

We can see from Fabian's equation that there is a linear relationship between miles (y) and gallons (x).Fabian's equation is in the slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept. Although we're not given the equation for Alexandra, we can find it using the slope formula, which is

\(m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\).

If we allow (8, 345.6) to be our x1 and y1 and (12, 518.4) to be our x2 and y2, our slope is

\(m=\frac{(518.4-345.6)}{(12-8)}\\ m=\frac{172.8}{4}\\ m=43.2\)

Now, we must find the y-intercept by plugging in 43.2 for m, 8 for x, and 345.6 for y into the general slope-intercept form and solving for b:

\(345.6=43.2(8)+b\\345.6=346.6+b\\0=b\)

Thus, the equation for Alexandra is y = 43.2x

Step 2: Plug in 1 for x for both Fabian and Alexandra's equations and subtract

Since x is is gallons, we plug in 1 for x for each equation and subtract Fabian's miles from Alexandra's miles to find how many miles less can Fabian drive one 1 gallon of gas than Alexandra:

Fabian:  y = 41.7(1) = 41.7

Alexandra:  y = 43.2(1) = 43.2

Difference of Alexandra and Fabian's miles:  43.2 - 41.7 = 1.5

Answers

Answer:

560

Step-by-step explanation:

140 ÷ 5 = 28

28 x 20 = 560

please mark me as brainliest and correct me if im wrong

You could either use the propotional method or unitary method, but I am going to be using the porpotional method since it is more quick.

Step 1

So first we would convert  the numbers givin into a fraction by putting 5 over 140 and 20 over x which is the question mark.

Step 2

Then we would cross multiply, so multiply numbers that are diagonal to each other .140 would multiply with 20 and 5 would multiply with x.

Step 3

After we multiply (we do not multiply 5 with anything so it is just 5)we would have the equation , x times 5=2800. Since  we need to isolate x we would take 5 and put it under 2800 so it would be 2800 divided by 5.

Step 4

After we divide 2800 by 5 we would have 560 which equals to x , making it the ounces needed to feed 20 animals at the shelter .

Summarise

To briefly explain this the way to find the answer would be 20x40 divided by 5.

PLEASE HELP!!! Lee can type 1 1/3 pages every 15 minutes. How many hours does it take him to type 10

Answers

Answer:

First, we know that:

1 1/3 = 4/3

10 2/3 = 32/3

15 minutes = 0.25 hours

Let's imagine that x (hours) is the time it takes Lee to type 32/3 pages.

From the information, we can tell that:

Lee can type:

4/3 pages in 0.25 hours

32/4 pages in x hours

So x should be:

x = (32/4 . 0.25)/4/3 = 2 (hours)

So it takes Lee 2 hours ro type 10 2/3 pages
