Same as before

total=(2w+75)(2w+35)=4w²+220w+2625

pool=75 times 35=2625

minus pool from total
4w²+220w+2625-2625=4w²+220w

One positive number is 5 times another number. The difference between the two is 1480.
Stella [2.4K]

Hey there!

Let's create a systems of equations with x and y to find our numbers.

x=5y

x-y=1480

Let's plug our x value into the second equation.

5y=y=1480

4y=1480

y=370

Now we multiply this number by five as the first equation says to get our x.

x=1850

Our numbers are 1850 and 370.

I hope this helps!

Answer:

2

Step-by-step explanation:

Linear equation form:  y = mx + b

(where m is the slope and b is the y-intercept)

The rate of change for a line is the slope.

Function 1:  y = 6

⇒ the slope is zero so the rate of change is zero

Function 2:  y = 2x + 7

⇒ the slope is 2 so the rate of change is 2

Therefore, 2 - 0 = 2

So the rate of change of function 2 is 2 more than the rate of change of function 1

Anybody good at this?<br> x - ( 9x -10) + 11 = 12x + 3 ( -2 + 1/3)
kenny6666 [7]
X - (9x -10) + 11 = 12x + 3( -2 + 1/3)
x - 9x + 10 + 11 = 12x - 5  ...........................(1/3-2) = -5/3 => x 3 = -5
-8x + 21 = 12x - 5
26 = 20x
x = 13/10

liraira [26]

Step-by-step explanation:

The key to solving word problems is in translation: turning word into  math

Below is a general approach to most/any word problem

1. Read through the whole question once, without lingering over details, to get some sense of the overall problem

2. identify and label the variables or unknowns in a way that makes it easy to remember what they stand for.

3. translate the problem into one or more equations, sentence by sentence, and be careful of the order in which you translate the terms

4. solve the equation(s)

5. check your work
